Abstract:

A low noise duplex bush chains with split rollers was developed through changing roller structure to reduce noise of bush roller chains. The split rollers could absorb more impact energy, mitigate meshing impact and reduce chain drive noise. The noise generated by different types of duplex bush roller chains was carried out to test in same speed, low noise characteristics of duplex sleeve chains with split rollers was verified. By analysis of testing data, noise level of duplex sleeve chains with split rollers compared with that of the other duplex bush roller chains was reduced by the average 3 ~ 8dB, and low 10 ~ 13dB than that of 16A simplex sleeve roller chains. The chains made chain drive significantly improve in the working environment, with steady transmission, strong bearing, low noise, and a significant noise reduction was achieved.

Abstract:

In order to mitigate the impact and the polygon effect of the chain and the sprocket during the meshing process and achieve the purpose of noise reduction, a Hlow noiseH nanostructured metal mesh-polyurethane composite material split roller chain was designed by means of changing structure and material of chain roller. Noise testing and frequency spectrum analysis were conducted, for the new roller chain and the other three kinds of the same specification chains with different structural rollers, on the closed force flow noise test bench researched and developed independently. The results show that the new roller chain can absorb some of the impact energy, and reduce vibration and noise of chain drive. The noise level generated by the new roller chain is significantly lower than the other tested roller chains, especially in high frequency and high speed. The difference in noise level is actually 3-11dB in driving sprocket speed of 1000r/min, and a significant noise reduction is achieved. The results also verify low noise characteristics of the new roller chain and rationality of design method.

Abstract:

A refined numerical analysis of the dynamic behavior of roller chain drives is performed considering the roller assembly as a three-layer structure with mechanical clearance between each two of the mechanical components. Instead of using analytical method, explicit finite element technique is utilized for modeling and simulating the dynamic behavior of chain drives. The complete standard geometry of sprockets and all components of chain links are used in the developed model with minor geometry simplification. A primary goal is to achieve a more complete understanding of the dynamic behavior of chain drives especially in the transient vibration response of the engaging rollers, which is crucial for noise emission calculation. The simulated velocity response of the engaging rollers and roller-sprocket contact forces achieved using the full model are compared with what found by the simple model which has been adopted in analytical study of chain roller dynamics.

Abstract:

A main reason that leads to the complex dynamic behaviors of roller chain is the impact during engagement. In this paper, a contact analysis methodology is proposed to study the complex dynamic behaviors of roller chain efficiently. Considering the actual tooth profile, a detection algorithm of roller-sprocket contact was presented. Multi-body dynamics was used to analyze the contact kinematics relationships for purpose of simulating the impact between roller and sprocket precisely. Based on Hertz contact theory, a non-linear contact model of roller-sprocket is developed. Introducing the model to the numerical simulation of a roller chain system, the results validate the effectiveness of the model.

Abstract:

This paper describes an improved chain link tension model for a simple two-sprocket roller chain drive. The model includes modified versions of previous models of the tension in the chain links, together with a new model for low-slack span tensions. The model allows the tension of a link to be calculated at any point in the chain drive more quickly and for a wider range of tight and slack span tensions than before. A new chain efficiency model is formulated, based on the losses due to sliding friction. Coupled with the chain link tension model, this can be used to predict the transmission efficiency of a chain. Experimental work undertaken on 0.5 in pitch industrial roller chains and bicycle chains has demonstrated that the chain efficiency model is accurate for moderate and high torque transmissions. At low torque, losses due to impact, adhesion and/or vibration become more significant and impair the accuracy of the model, particularly for heavier, industrial roller chains. The chain efficiency model enables certain design trade-offs to be carried out, such as the selection of the size of the overall system to achieve the right balance of transmission efficiency and weight.

Abstract:

Purpose This study aims to introduce a novel technique which helped in quantifying the wear performance of a roller chain which was lubricated by using the palm oil-based hexagonal boron nitride (hBN) nanoparticles (nano-biolubricant). Design/methodology/approach The efficiency of the nano-biolubricant was evaluated by using a custom-made roller chain tribometer, at different resistance torque values at a constant speed and running time. Prior to the test, 2 different lubrication conditions were applied. The mass loss and elongation behaviour of a roller chain was selected as a degradation metric for monitoring the amount of the chain wear. The predominant wear mechanism of a roller chain was identified by surface morphological analysis. Findings Regardless of the lubrication conditions, the wear performance of the roller chain was significantly increased, at increasing resistance torque values. Higher wear was noted when the roller chain was lubricated using a nano-biolubricant, however, the wear curve showed a promising high chain life. The predominant wear mechanism involved is abrasive wear. Originality/value Although an increase in the elongation during running is based on the wear between the pins and roller, none of the earlier studies quantified the wear performance of a roller chain under differing lubrication conditions. Hence, for bridging the gap, this study described a new method for measuring the wear performance of the roller chain which was lubricated using the palm oil-based hBN nanoparticles or a nano-biolubricant.

Abstract:

Roller conveyor chains are common used to transport goods in production lines or assemblylines, such as pallets, cars or steel coils. They are sometimes used in severe environments, soiled withwater, foreign particles, chemicals or other contaminants. Normal use will result in wear of the componentsof the chain which can lead to unexpected failure and costly production downtime. Today, few literature onthe wear of conveyor chain is available and there are almost no reliable test-rigs to generate and measurechain wear in a reproducible manner. In this research the different components of conveyor chains and theloading conditions are described. Additionally, the applications and (dis)advantages of chains with polymerrollers are discussed. The chain wear mechanisms found in literature are listed. Abrasive and adhesivewear between pin, bushing, roller and track are discussed. From the contact mechanics of the chain andpressure-velocity limit of the roller materials, the design constraints for the laboratory test-rig were derived.The capabilities and working principles of the developed test-rig are explained in this paper.

Abstract:

The sleeve of roller chain periodically squeezes the pin during the process of chain transmission. The lubrication oil located in the gap of the sleeve and pin will be pushed out and cannot be restored automatically. The absence of sufficient lubricating oil can cause friction, wear, and even the roller chain failure between the pin and the sleeve. This article presents a novel method and a new type of chain structure to lubricant roller chain with ferrofluids, which is capable of prolonging the service life of roller chain. The results show that ferrofluids can be remained in the clearance between the sleeve and the pin shaft under the effect of external magnetic field. The ferrofluids that were squeezed out of the clearance can be restored automatically, which ensure the reliability of chain transmission. And the external magnetic field effectively prevents the chain lubrication leakage due to the edge effect of the magnetic field.

On a roller chain drive, if the incoming engaging roller moves tangent to the pitch circle at the moment of engagement, no roller-sprocket impact should occur. Based on such a notion, an engagement guiding mechanism is proposed to make this possible. The algorithm of kinematic design of the mechanism is presented.

Abstract:

In this paper, new sprocket tooth profile is developed to reduce polygonal action and meshing impact under high speed. The new conjugated profile is derived by modifying involute profile to guarantee that the moving distance of chain is equal to the arc length of pitch circle that sprocket rotates at the same time and the centre line of chain at tight side is tangent to the pitch circle always. An asymmetrical modification method for the sprocket tooth profile is also proposed. The multi-body dynamic model of timing mechanism in engine with the intake and exhaust sprockets is developed. The fluctuation and meshing impact of chain are analyzed under different rotating speeds. The results show that new developed sprocket profile can efficiently reduce meshing impact and friction of chain. The stability of chain transmission under high speed can be improved.

Goal . Develop the design of the drive plate chain and methods for determining the optimal parameters of the chain transmission. Methods. Analysis of the designs of standard drive bushing and roller chains, as well as the drive plate chain with internal engagement. Determination of ways to increase the durability of these chains and chain gears from the condition of ensuring the wear resistance of their hinges and increasing their technical and economic indicators. Results . The analysis of designs of standard drive bushing-roller chains and drive plate chains with internal gearing is performed. A promising design of the drive plate chain has been developed. The optimization of transmission parameters, both with standard chains, and with the chain proposed by the authors, providing an increase in their durability and efficiency. In this regard, a method has been developed for determining the greatest elongation of standard chain links, as well as the chain developed by the authors, from the condition of wear resistance of their hinges. A method for determining the optimal transmission ratio of these chain gears has also been developed. It is established that the gear ratio of the transmission with the drive plate chain developed by the authors is determined primarily by the accuracy of manufacturing its hinges. With sufficiently precise manufacturing of chain hinge parts, the gear ratio can be significantly increased, up to u=10 and higher. This will allow you to use gears equipped with this chain in drives with a large gear ratio.

Abstract:

In the present study, a novel approach to estimating the efficiency of roller chain power transmission systems is proposed based on sliding friction losses and damping force. The dynamics model is taken into account between chain links with lateral offset owing to the derailleur system. Frictional losses were calculated according to Coulomb’s law of friction, and the damping force was dependent on the damping coefficient. The effects of rotational speed, load, derailleur system, and damping coefficient on transmission efficiency were analyzed. The test stand of the roller chain power transmission system was set up to verify the estimated efficiency, and the results showed a good correlation, demonstrating the validity of the chain power transmission efficiency estimation.

Full text

Abstract:

The magnitudes of the impacts in chain drives are a function of the sprocket speed, chain link pitch, the number of links in the chain span, and the mass distribution within each link. The impulsive force may be viewed as equivalent to the effective mass of the chain span being concentrated at the roller and applied to the sprocket at the impact velocity. This effective mass is derived in this paper from first principles using Lagrange’s impact equations. Contrary to accepted rules, it was found that the effective mass decreases with increase in chain length. Moreover the impulsive force on the links of the chain span decreases exponentially with the distance from the impacted roller. Motion characteristics of the chain immediately after impact are also discussed.

Abstract:

The purpose of the study is to evaluate the geometric parameters of the plates of roller chains used in the supply of gas distribution mechanisms of motor vehicles. The method used is an analytical representation of the dependencies of the plate shape. The relevance of the proposed approach is justified by the great complexity of pre-design studies for choosing the type of drive chain of various mechanisms. Main results-dependences are proposed for determining the area of plates both with the "eight" type shape of the inner link of a standard roller (bushing) chain, and plates with straight side faces, and it is reasonable to choose the design of the drive chain for the specified operating loading conditions. Dependencies have a scientific novelty and practical significance when used in the production activities of employees of technological departments and design services of machine-building and auto repair enterprises.

Abstract:

A kinematic analysis has been developed for the motion of roller chain drives, which is exact for relatively slow-speed chain drives with negligible wear. The results shed new light on chordal or polygonal action, and the associated impact velocity and motion fluctuation of the chain drive. The results have also revealed the existence of a remarkable degree of sensitivity of chain performance with respect to center distance including discontinuities in the motion derivatives. This in turn provides a new opportunity for the optimization of chain drives by optimizing center distance both in the design stage, as well as during installation and maintenance.

Abstract:

In this paper, formula for calculating the reliability of single-chain drive system and formula for calculating the reliability and efficiency of drive system of multi-roller ironing machine are presented based on reliability design theory and the theory of mechanical efficiency calculation. The results illustrate that the reliability and efficiency of existing drive system are lower. Therefore, improvement measures are proposed: use high-quality bush roller chain that shall be regularly maintained and changed; the chain drive shall be replaced with gear drive.

Abstract:

A detailed numerical simulation analysis on the dynamic response of intermittent roller chain drive has been carried out in this study. Instead of using analytical method, three dimension solid modeling software and multi-rigid body dynamic analysis software are utilized for modeling and simulating the dynamic behavior of chain drive. The longitudinal vibration response of the chain links is concentrated on, which aims to reveal the dynamic characteristics of the intermittent chain drive under varying motion laws such as the modified sinusoid (MS), the modified constant velocity (MCV) and the unsymmetrical modified trapezoid (UMT). The simulation results can enable designers to require information on the analysis and design of mechanisms with the intermittent roller chain drives.

Abstract:

This paper deals with the roller chain commonly used for transmission of mechanical power on many kinds of industrial machinery, including conveyors, cars, motorcycles, bicycles, and so forth. It consists of a series of four components called a pin, a bush, a plate, and a roller, which are driven by a sprocket. To clarify the fatigue damage, in this paper, the finite element method (FEM) is applied to those components under three different types of states, that is, the press-fitting state, the static tensile state, and the sprocket-engaging state. By comparing those states, the stress amplitude and the average stress of each component are calculated and plotted on the fatigue limit diagram. The effect of the plastic zone on the fatigue strength is also discussed. The results show that the fatigue crack initiation may start around the middle inner surface of the bush. As am example, the FEM results show that the fatigue crack of the inner plate may start from a certain point at the hole edge. The results agree with the actual fractured position in roller chains used in industry.

Abstract:

In order to apply silent chain on conveyor, double-pitch time-sharing meshing silent chain is proposed, and by comparing with traditional silent chain with same pitch, the self-weight 20%~30% of this chain is reduced. According to meshing theory, parameters are designed for double-pitch time-sharing meshing silent chain to make each tooth profile of chain plate involving in meshing and time-sharing load bearing and to change the meshing state of traditional silent chain in the meshing process. Noise comparison test is conducted to verify its excellent performance, when rotate speed is 350r/min, the noise of double-pitch time-sharing mesh silent chain is 4.6dB lower than traditional double-pitch roller chain. Meanwhile, 250h abrasion test is conducted, the abrasion elongation of chain is 0.23% after test, which is significantly lower than traditional double-pitch roller transport chain. The rationality of new chain design is proved by test result, which provides theoretical basis for applying silent chain on conveyor.

Abstract:

Purpose The purpose of this paper is to study the influence of surface precision on the lubrication state of the roller chain under adequate and rare oil supply conditions, respectively. Design/methodology/approach The straightness error and roughness error of the pin generatrices were measured and the influence of surface precision on the lubrication behavior under steady state and reciprocating motion was studied through optical interference experiments. Findings The lubrication state is strongly influenced by the surface precision of the roller surface both under adequate oil supply and rare oil supply conditions. Originality/value In industrial applications, the machining errors of parts cannot be completely eliminated. Studying the influence of the surface precision on the lubrication behavior of pin–bush pairs can provide the experimental basis for the optimal design of the bush roller chains.

Abstract:

Experimental observation has shown that the most significant noise source in roller chain drives is from the impacts between the chain and the sprocket during their meshing process. Despite its importance, studies have not been made to thoroughly analyze the chain/sprocket impact dynamics and their interaction with the vibrating, axially moving chain structure. This paper presents a novel analysis which integrates the local meshing phenomena with the global system. An axially moving chain interacting with local impacts has been modelled and the momentum balance method is employed to derive the impulse function. A study is carried out to quantify the intensity of subsequent impacts. It is found that the impact intensity is significantly affected by the vibration characteristics and response of the moving chain, and vice versa. The classical quasi-static approach will create errors in predicting the impulse magnitude and system response. Meshing frequencies that will cause maximum and minimum impulses are analytically predicted. This fundamental investigation provides new insight into roller chain dynamics, which is an essential step toward the design of quiet chain drives.

Abstract:

Possible concept solutions of chain drives are analysed in this paper in order to point out the benefits of chain drive application and, in particular, the possibility of application of multi-level chain drive. The paper also analyses the possibility of replacing the gear drives with chain drives, which, in the case of short-term drive and using the same direction of rotation, enables a slightly simpler drive solution. The paper doesn’t consider difference between the roller and gear chains application because these two types of chains can be used very successfully. Also, the possibility of using timing belt drive is not considered, but it can be also used very successfully in this type of drive, but only as a transmission of motion.

Abstract:

This paper proposes a new kind of detection method based on CCD to measure geometry sizes and roundness error of chain board of roller chain. Image is collected, and is input into computer, then is processed by a series of steps such as grey level transformation, image smoothness, lower filtration, and threshold value selection, etc. The measurement of the geometric parameters and the roundness error relies on the image contour. Roundness error is evaluated by Minimum Region Law. The diameter of the holes and the distance between the axes of two holes are calculated and measured by self-developed program. Roundness error of chain board is less than 8μm, and the distance error between the axes of two holes is 9μm. The diameters of the holes are 4.467mm and 4.461mm respectively. The reasons of measurement error are also analyzed. Theory analyses and experiment show that it is feasible to measure the geometric sizes and roundness error of roller chain by this method, which is both efficient and practicable.
