Abstract:

The paper deals with the problem of timing belt pitch significance for the dynamics of a timing belt transmission gear motion. Specific pitches of timing belts have been used for many years. They were previously reserved for belts made of rubber, while another group of pitches was intended for belts made of polyurethane. This division ceased to apply recently, and in addition there are belts with pitches which have not been used before, such as HTD9M or AT15. The paper presents the parameter that makes the pulley diameter and the pitch dependent on the number of teeth involved in meshing (coupling) with a pulley. It is an equivalent of the coverage factor occurring in cylindrical timing gears. Earlier studies on that parameter did not take into account the teeth unevenly spaced over the width of the belt. New pitches of belts may occur in "mass production" applications and they are applied more and more often. Thus it is important to bear in mind the consequences of changing the pitch of the timing belt in transmission gear structures.

Abstract:

Six kinds of torque-splitting and speed-converging metal V-belt IVPST were raised; their global speed ratio and torque ratio of metal V-belt CVT output to metal V-belt IVPST output were derived. Two different torque-splitting and speed-converging metal V-belt IVPSTs were sum up: series and parallel metal V-belt IVPSTs. In series metal V-belt IVPST, speed ratio changing rate and torque ratio were related to gear ratio of planetary gear train and fixed gear transmission, but in parallel metal V-belt IVPST, that were only related to gear ratio of planetary gear train.

Abstract:

As a new type of gear transmission, the gear transmission with meshed medium belt has advantages of reducing vibration noise and friction damage on the gear surface. During the process of the gear transmission with meshed medium belt, the friction and wear is mainly occurred on the medium belt, so the service life of the medium belt has a direct effect on the performance and efficiency of the transmission system. The friction and wear mechanism of the medium belt is researched and effective ways to prolong the service life of the medium belt are given in this paper.

Abstract:

This paper presents the problem of phenomena occurring at the contact of a timing belt and a pulley. Depending on a belt size range these phenomena differ significantly. There is no indication as to what solutions are optimal for drive belts. The analysis of the coupling process and performance tests have shown that the drive belt should have a cord of very good mechanical properties and its raceway side should be made from the material of a low friction coefficient against the pulley material. A flat belt in power transmission and conveying systems cooperates with several elements consisting of timing pulleys, tensioners or guiding rails. In gear with timing belts they depend strongly on characteristics of the process as well as the type of friction. In recent constructions, producers of timing belts are very much concerned about achieving as much slippery surface as possible. The work describes the problem of friction on different surfaces as well as its influence on gear lifetime. Research results confirm that on many surfaces bigger coefficient of friction is expected.

Abstract:

Solid models of the involute gear, the gear with meshed medium belt and the medium belt were built with the PROE software. Then the steady-sate temperature field of the solid model was analyzed with ANSYS software. The result showed that the body temperature distribution on the tooth face was not effected by the medium belt. Different duty parameters were selected to analyze the highest temperature of the medium belt. So theory basis for choose of the medium belt and the duty parameters was provided.

Abstract:

Three configurations of occupant restraint systems were evaluated for use in military vehicles. Restraint configurations consisted of a 23 (lap and two shoulder belts), 3+2 (standard 3-point lap/shoulder belt plus secondary shoulder belt) and 5-point (two shoulder, two lap, and one crotch belt). All systems had a single point release feature. Human factors evaluation entailed assessing ingress/egress, functional operation (control reach) and accommodation (fit). Testing included with and without full gear. Eleven soldiers with military vehicle driving experience participated in the evaluation. Results for egress testing showed that the 5-point was slightly faster than the 3+2 and the 23. Results for the ingress testing showed that ingress time was directly related to the number of connections with the 3+2, 23 and the 5-point reflecting fastest to slowest times. Wearing full gear significantly increased ingress time but had minimal effects on egress times. No major accommodation issues were noted.

Abstract:

Reinforcement of the tooth belts is the element responsible for the transmission of the torque. Its structure is related to the dynamics of the belt and such important parameters as the stiffness of running stability on pulleys and above all, the pitch stability. The axis of symmetry of the reinforcement in the vertical direction of the belt is the reference point of the belt geometry as well as the neutral axis of stresses caused by bending. On the arc of the contact between belt and pulley, over the reinforcement, the belt is stretched, and below it is compressed. In the tooth belts, there are various solutions of the carrier layer, in terms of the materials used, but also types of fibers, quantity of the fibers, etc. The paper presents the results of analysis of the carrier layer of the most popular tooth belts with T10 and AT10 trapezoidal teeth. The paper shows possible direction of choice of the construction materials of the carrier layer and their importance for the dynamics of the gear with the tooth belt.

Abstract:

AbstractThe presented paper provides the alternative options for determining the condition of belt gear based on the testing and monitoring. In order to carry out experimental measurements, a newly developed device for testing, monitoring and diagnostics of belt drives was designed, as well as the possibility of determination of limit states by extreme loads. The designed measuring stand allows to determine the point of destruction of the belt for an extreme load. The main objective of the experimental measurement was to determine the slip of the wedge-shaped belt. The slip was evaluated by the coefficient of belt creeping and the specific belt slip by means of the measuring stand. The measurements on the proposed device can be made when the input speed from the electric motor and the transmitted torque of the belt gear are constant while the tensioning force of the belt drive is changing or the measurements can be made when the tensioning force and input speed of the belt drive are constant and the torsional moment changes. The monitoring of specified parameters for determining the belt gear slip is made by means of sensors located at predetermined locations from which data is processed by a PC. In the paper, the analytical calculation is processed, from which the values are compared with the values measured on the proposed device.

Compared with straight bevel gears, spiral bevel gears have been more widely used in industry due to their better transmission performance and lower noise. Spiral bevel gears are generally produced by cutting methods, such as face-milling and face-hobbing methods. However, the cutting methods need to use special cutting tools and implement on dedicated cutting machines. For the production of small or moderate amount of gear manufacturers that isn’t meet the cost. Considering cost and flexible manufacturing of bevel gears in small and medium batch size, five-axis machine center is another good option compared with the dedicated bevel gear cutting machine. Company Heller in cooperation with company Gleason offered a new solution for bevel gear cutting on its five-axis machine tool. Here, a bell-type milling cutter with indexable inserts replaces the special face-milling cutterhead. However, it did not disclose the details of such application due to commercial considerations. The main goal of this paper is to establish a mathematical model of spiral bevel gear using a bell-type milling cutter on a five-axis machine center. First, a mathematical model of spiral bevel gear with the Gleason SGDH cutting method is established as a standard gear, and a virtual machine is proposed to provide movements between the cutter and the work gear. The generating gear purely rolls with the work gear that will obtain the tooth surface. This model contains three modules: a cutter, an imaginary generating gear, and the relative motion between an imaginary generating gear and work gear. And then, conversion from the virtual machine enables derivation of the nonlinear coordinates of the CNC five-axis machine. Finally, flank topographic errors are evaluated by compared with the theoretical tooth surface, and the five-axis tool paths is confirmed using VERICUT NC simulation software.

The company Gleason and Heller released a new cutting method for spiral bevel gear and hypoid gears in 2013. This cutting method adopts a bell-type milling cutter on a general-purpose five-axis CNC machines. And it is flexible and suitable to manufacture large-size gears in small-scale production. General-purpose five-axis CNC machines are cheaper and easier to be obtained compared to the dedicated bevel gear cutting machines. However, the mathematical model of this method is not revealed under commercial considerations. This research aims to establish a mathematical model of bell-type cutting method based on the target tooth surface. The tooth surface is first approximated using NURBS surface fitting method. And the mathematical model of bell-type cutter is established. The five-axis coordinates of head-table type and table-table type five-axis machines are then derived through inverse kinematics. In addition, fitted tooth surface are subdivided to reduce cusp during milling process, and let the surface of workpeice meet the roughness requirement. We develop a spiral bevel gear manufacturing software base on the bell-type cutting method. NC codes for Siemens 840D controller can be automatically generated according to the derived five-axis coordinates. After NC data and tool path are checked using VERICUT NC simulation software, a cutting experiment for producing the ring gear on the table-table type five-axis machine is done. The measurement result verifies the correctness of the proposed mathematical models.

Abstract:

The aircraft landing gear and its associated systems represent a compelling design challenge: simultaneously a system, a structure, and a machine, it supports the aircraft on the ground, absorbs landing and braking energy, permits maneuvering, and retracts to minimize aircraft drag. Yet, as it is not required during flight, it also represents dead weight and significant effort must be made to minimize its total mass. The Design of Aircraft Landing Gear, written by R. Kyle Schmidt, PE (B.A.Sc. - Mechanical Engineering, M.Sc. - Safety and Aircraft Accident Investigation, Chairman of the SAE A-5 Committee on Aircraft Landing Gear), is designed to guide the reader through the key principles of landing system design and to provide additional references when available. Many problems which must be confronted have already been addressed by others in the past, but the information is not known or shared, leading to the observation that there are few new problems, but many new people. The Design of Aircraft Landing Gear is intended to share much of the existing information and provide avenues for further exploration. The design of an aircraft and its associated systems, including the landing system, involves iterative loops as the impact of each modification to a system or component is evaluated against the whole. It is rare to find that the lightest possible landing gear represents the best solution for the aircraft: the lightest landing gear may require attachment structures which don't exist and which would require significant weight and compromise on the part of the airframe structure design. With those requirements and compromises in mind,The Design of Aircraft Landing Gear starts with the study of airfield compatibility, aircraft stability on the ground, the correct choice of tires, followed by discussion of brakes, wheels, and brake control systems. Various landing gear architectures are investigated together with the details of shock absorber designs. Retraction, kinematics, and mechanisms are studied as well as possible actuation approaches. Detailed information on the various hydraulic and electric services commonly found on aircraft, and system elements such as dressings, lighting, and steering are also reviewed. Detail design points, the process of analysis, and a review of the relevant requirements and regulations round out the book content. The Design of Aircraft Landing Gear is a landmark work in the industry, and a must-read for any engineer interested in updating specific skills and students preparing for an exciting career.

Abstract:

Introduction to Equestrian Sports offers parents and riders who are new to the scene detailed descriptions of what is involved in each of the four main disciplines: hacking/showing, dressage, showjumping and eventing. It is equally beneficial for those wanting to change from one type of competition to another. Each discipline description includes how it originated, its current status, types of classes, levels of competition, what rules apply, who runs the competitions and how they are judged. 'Ground rules' are explained, based on the author's considerable experience, to help take the mystery out of competitions, such as how to find out what competitions are taking place and how to enter, which classes are being judged, what to wear, what to do when you arrive, where best to park, where you can and cannot warm up, checking your gear and reporting to the judge. Other topics include how to prepare for a competition, from one month before to the night before the event, and the equipment required to compete, from choosing a horse to what rugs will be needed. Finally, illustrations of arenas, website links and examples of competition programs are provided to help beginner riders further understand their chosen sport. Introduction to Equestrian Sports is not another 'how to ride' book, but a practical, hands-on guide to make equestrian competitions enjoyable for all riders.

Abstract:

From the standpoint of the development of possibilities of application in theory and practice, the works of Prof. B. A. Perepelitsa from Kharkov Polytechnic Institute and his disciples to develop an applied methodology of multiparameter mappings in relation to the profiling and functioning of complex curvilinear objects and transmission mechanisms in mechanical engineering, mainly with examples of gears, are presented. The work substantiates the relevance of the study of gears with a complex non-involute profile of the side surfaces of the teeth, which in some applications have advantages over involute gears and are devoid of some of their drawbacks associated with quality indicators. A technique for obtaining mating surfaces of the teeth of non-invasive gears as envelopes of the specified surfaces of the teeth of tools is described. A scheme for forming pairs of non-involute gears, from which a gearing can be composed, is proposed. At the same time, diamond-abrasive tools are considered as shaping the working gear profile in its cutting according to the copying scheme and finishing according to the rolling honing scheme. In the first case, the profile of a special shaped tool on a high-strength metal bond is supported by a master electrode according to the scheme of the anodic connection of the tool into the electric circuit of dressing, similar to diamond spark grinding. In the second case, the use of gear wheels-hones on elastic ligaments is shown. It is shown that to obtain the mating surfaces of the teeth of two non-involute gears, two tool rails can be used with the profiles of the side surfaces of the teeth opposite to each other. As a nonlinear profile of the tooth lateral surface of the tool rail, some part of one of the simulated flat kinematic curves is considered. A description of the program developed in accordance with the described method is given, which allows you to calculate the geometric characteristics of the shaped profiles of the gear pair wheels, visualize the shaping process, and also determine the quality indicators of the gearing. Thus, the prerequisites were created for choosing from the resulting geometric modeling of the curve field of such tooth profiles of the tools, which would provide the most rational combination of the tooth profiles of the gears processed by them and the required quality parameters of the gear teeth. The results of the study of the pressure ratio between the teeth of a gear and the overlap ratio of gears when choosing the shape of the tooth profiles are presented. A series of numerical experiments for gearing, formed by pairs of tool rails with different profiles of the side surfaces of the teeth straight, convex and concave, as well as convex-concave were performed. It is shown that non-involute gearing can have large reduced radii of curvature (and consequently smaller pressure coefficients) at the points of tangency of the profiles compared to involute gearing with a slight increase or decrease in the gearing overlap ratio. The most preferable is the variant of the rails with convex and concave tooth profiles, which provides the best values of both quality indicators of the engagement.

Abstract:

A new tensioner mechanism is designed for a belt driven transmission system with variable gear ratios. The preliminary design of such transmission system includes a morphing driver pulley, a driven pulley with constant radius, and a tensioner. With the aim of changing the gear ratio, the radius of the morphing pulley (driver) varies gradually through a stepwise shifting procedure. Hence, the geometry of the belt and pulley system, including the tensioner pulley position, changes noticeably while the shifts occur. A regular tensioner, commonly used in the belt and pulley systems, includes a linear spring, which is attached to an idler pulley. This type of tensioner is designed and installed in the transmission systems with respect to the geometry and loading condition in order to guarantee a certain value of static pretension in the belt. The longitudinal vibration of the belt and pulley system is also controlled by setting proper value of tensioner spring stiffness and other dynamic parameters. The regular tensioner is commonly modeled as a linear spring. These tensioners are mainly used for the belt and pulley systems with constant gear ratios. In the case of variable drive system, while the radius of the driver pulley changes, a large displacement in the tensioner pulley position is expected. This large displacement results in large variation into the belt static tension, and might cause unpredicted fatigue failure in the belt or pulleys. Lower values of static tension can cause belt dynamics instability in a belt driven system. [Wickert 1990] A new tensioner is proposed for the morphing pulley transmission system in order to control the static tension and the belt longitudinal vibrations for different gear ratios. The tensioner includes a linear spring that is connected to the tensioner pulley via a convertor mechanism. The convertor system consists of a traveling pin and guide rail mechanism. The traveling pin is connected to the tensioner pulley while the rail is attached to the linear spring. Using this mechanism, the tensioner system behaves like a variable spring element. By defining a proper curve, it is possible to maintain the static tension within the desired range and control the longitudinal vibration of the belt and pulley system. The design parameters of the tensioner system are investigated through a linear optimization process in order to minimize the longitudinal vibration of the belt as well as the pretension.

Abstract:

Gear train is the most applied in the heavy duty engine timing system on the benefit of reliability, durability, timing accuracy, maintenance, and high torque transmission. But the gear train is vulnerable to rattle and whine noise due to many serial gear connections, which lead to more possibility for gear backlash impact and gear transmission errors compared with chain and toothed meshed belt timing systems. Furthermore, normal heavy duty diesel vehicles like truck and bus are well vibration isolated from engine at gear noise frequency range. Therefore, noise source control is inevitable in the developing process in heavy duty diesel vehicles. The objective of this paper is to reduce timing gear whine noise in the engine developing process for heavy duty vehicles. Main focus is modification of gear tooth shape in the proto engine developing process considering vehicle driving modes. To investigate engine timing gear whine noise, transmission error analysis was executed in accordance with proto type gears and optimal gear tooth modification was induced by transmission error analysis, engine bench, and vehicle test.

Abstract:

This study experimentally measured the efficiency of new generation bicycle hub gears. Since efficiency of bicycle drivetrains can be very close to 100% and vary by small amounts between gears bias errors and measurement accuracy must be identified and controlled. For this study an ergometer frame was altered to support research test equipment. A 1 HP motor and gearbox were used to drive the crankshaft. The hubs were attached directly to the steel flywheel using shortened bicycle spokes, eliminating extra chains or drive components. This setup minimizes measurement uncertainty in the drivetrain. Force-transducers were used to measure the motor and flywheel torque, and two magnetic reed switches were used to measure the speed of the motor and flywheel. Efficiency for each individual gear in each hub was calculated for 14 different power speed combinations. The efficiency of each gear was plotted against flywheel Torque, and an exponential model was fit to the data. This model accounts for known variations in efficiency with power and speed, and provides insight into the torque-speed-efficiency relationship. Four internally-geared hubs were measured and compared with a single speed direct drive train and a belt drive. The internal planetary gear hubs measured were the Shimano Alfine 11, Rohloff 500/14 Speedhub, SRAM Dual-Drive, and the Sturmey Archer X-RK8(W). In addition a single-speed direct chain drive, a single-speed belt drive, and a 7-speed derailleur system were measured. The efficiency of the Shimano Alfine ranged from 90.4% to 96.6%. The efficiency of the Rohloff speed hub ranged from 95.8% to 99.5%. The efficiency of the Sturmey Archer hub ranged from 84.6% to 99.8%. The efficiency of the single speed chain drive was found to be 99.71% and the belt drive 98.0%. The efficiency of the 7-speed derailleur ranged from 97.7% to 99.4%. These values found for efficiency are comparable to other studies.

Abstract:

This paper unveils a new principle for automatic transmission, which may greatly simplify the current automatic transmissions and improve their efficiency. Unlike traditional automatic transmission based on torque converter/planetary gears, automatic transmission systems based on V-belt variable speed drive, or traditional transmission with electrical control, this new approach does not rely on the gear ratio or radii of the driving and driven wheel to change the speed ratio. The speed change in the new approach is achieved by an elastic belt on two fixed-diameter pulleys. The belt elongates in proportion to the load applied, and the driving pulley of fixed diameter has to rotate more to accommodate the increased length of the belt due to the load increase, consequently reduces the speed of driven pulley. This self-sensing, self-adjusting, and fully automatic drive system is pure mechanical without the need of electrical or hydraulic control. Based on this novel kinematic principle, the simplest automatic transmission in the world may be designed, manufactured, and used.

Abstract:

A Continuously Variable Transmission (CVT) provides a continuum of gear ratios between desired limits. CVT is a promising automotive technology and a sundry of models has been researched to realize the potential benefits of a CVT. CVT, being a highly nonlinear system, has a definite operating regime where it is able to maximize the torque transmission. The numerical model presented in this paper is difficult to solve because of its sensitivity with respect to the initial operating conditions such as initial belt tension, axial forces, and driven preload. The present research focuses on using Genetic Algorithms (GA) to identify these operating conditions and to understand the various dynamic interactions in a metal pushing V-belt CVT. This paper uses continuous Coulomb friction approximation theory to model friction between the belt and the pulleys. The computational scheme, the mathematical models, and the results corresponding to different loading scenarios are discussed.

Abstract:

From 1877, the continuously variable transmission (CVT) showed up and became popular in the transmission market, and it is expected to be the main stream of transmission in the future. This paper attempts to verify a new principle of CVT which is achieved by elastic deformation of an elastic belt. Unlike traditional transmission, this new approach does not rely on the gear ratio or the radius of the driving and driven wheel to change the speed ratio. The speed change is achieved by an elastic belt on two fixed-diameter pulleys. The belt elongates in proportion to the load applied, and the driving pulley has to rotate more to accommodate the increased length of the belt due to the load increase, consequently reduces the speed of driven pulley. This self-sensing, self-adjusting, and fully automatic drive system is pure mechanical without the need of electrical or hydraulic control, and greatly simplifies the current transmission system. This paper will introduce the new principle of automatic transmission and discuss the experimental results of the speed changes, and therefore prove the feasibility of the new principle of automatic transmission.

Abstract:

Abstract This study investigates the varying-order analysis based on mechanism, and realizes it in dynamic signal processing of rotary machinery. Firstly, the synthetic signatures consisting of fixed-order, varying-order components and resonance-related ones as well are designed to validate the developed computation schemes. Secondly, this work takes an electrical scooter as a test bench, which some experiments have been conducted on. The noise and vibration signatures are measured and processed to characterize different spectral components and identify their sources. Some of the annoying ones belong to fixed order (e.g., gear whine noise), varying order (e.g., CVT-belt noise) and structure resonance (e.g., the structure-borne noise originated from the CVT housing). Therefore, the concerned noise/vibration can subsequently be coped with via machine component modification.

Abstract:

Abstract This paper discusses methods to retrieve design(s) from a design library in order to achieve a better initial starting point for the iterative model of the design process. The motivation for doing this is to reduce the extensive analysis time required for many iterative design problems. Starting a design at a favorable initial point should help reduce the number of iterations. Four initial design methods have been investigated varying from a simple non-library method to methods that use designs from a library. To evaluate the effectiveness of these methods, the initial design methods were tested on four example problems. They are, a cantilever beam, a gear-pair, a v-belt and an extruder-die. It was found that the number of iterations reduced approximately as 1/n, where n is the number of stored values in the design library.

Abstract:

Despite great progress recently made on applications of in-wheel motors in electric vehicles, almost all production or near-production electric vehicles still utilize mechanical speed reduction systems for transferring torque from the traction motor to wheels for the purposes of torque augmentation and speed reduction. These systems in general fall into three categories, i.e. fixed ratio, stepped variable ratio, or continuously variable ratio. In China, most electric cars retrofitted from internal combustion engine propelled vehicle models use gear reduction systems of a fixed speed ratio, in order to minimize the time to market. Typically a conversion is made to the original 5-speed manual transmission by taking out a few unused gear sets. With the rapid growth in electric vehicle industry, some gearboxes of fixed speed have been engineered and they typically have a layshaft configuration. Most of them still do not come with a “park” gear due to a lack of understanding on customer’s needs. As an exception, a transmission of fixed speed ratio dedicated for electric vehicle applications has been developed at the Electric Vehicle R&D Center, Chinese Academy of Sciences (UCAS). Among electric vehicles announced by domestic vehicle manufacturers in China, some employ 5-speed manual transmissions (MTs) or automatic transmission (ATs) that typically found in traditional vehicles. From the driving convenience, transmission efficiency, or cost standpoints, these transmissions are, in general, not appropriate for applications in electric vehicles. The “misusage” of these transmissions has often something to do with their availability rather than suitability. A great deal of effort has been put into the research and development of automated mechanical transmissions (AMTs) in China to date. Significant progress has been made to the reduction of shift time, improvement of shift quality, and optimization of the mechanical components. Continuously variable transmission (CVT) is considered to be an important trend in drivetrain technology. However, the pulley-belt types of CVT commonly seen in traditional vehicles are not proper for electric vehicle applications. An EVT dedicated for electric vehicles is under development at UCAS, in which the power from an electric motor of dual-rotors is coupled by means of a planetary gear set, allowing continuous variable of the output speed. In summary, the electric vehicle drivetrain technology in China is undergoing rapid advances, which will impact the development of electric vehicle industry at home and abroad.
