Abstract:

In the marine gear system, the vibration of gears is transmitted to the ship foundation through shafts, bearings, housing, and isolators, and then the underwater noise is generated. Analyzing the vibration transfer properties and identifying the critical path can provide guidance to the low-noise design of the gear system. In this paper, a coupled gear-housing-foundation dynamic model is proposed for a flexible supported gear system, in which the flexibility of each subsystem and the coupling relationship between them are taken into account.

Abstract:

This study is focused on some features of geometry and kinematics of gear hobbing operation. The principal goal is to determine minimal hob idle distance required for complete generation of the gear teeth. This task is of importance in two aspects: to cut hobbing time and to reduce axial size of a hobbed cluster gear, gear with shoulder etc. The necessity of cutting hobbing time is evident. Reduction of axial size of a hobbed gear cluster leads to reduction of size and weight of the gear cluster itself and of the gear train housing, and therefore its necessity is also evident.

The developed asymmetric gear transmissions for UAV modernization make it possible to increase payload capacity and integrate more powerful engines.

Abstract:

The dynamics of spiral bevel gears have gained increasing importance due to concerns relating to noise and durability. This is because the mesh force acting on the gear teeth is amplified under dynamic conditions, potentially reducing the fatigue life of the gears. Furthermore, a sizable dynamic force can be transmitted to the housing, inducing structure-born gear whine. The elasticity of the bearings can influence the dynamics of spiral bevel gears. In this article, the finite element formulation of a spiral bevel geared rotor dynamic system is applied to investigate the influence of bearing

AbstractThe optimization of load sharing between planets is one of the most important goals in planetary gearbox design. Unevenly distributed load will cause locally higher flank pressures and therefore, less durability of gears and bearings. Furthermore, unevenly distributed or fluctuating loads can cause excitations in the gear mesh and structural vibrations. The load sharing in planetary gear stages depends on the individual stiffness conditions in each mesh position. The stiffness is not only influenced by the gear geometry but also by the surrounding structural elements like shafts, housi

Abstract:

When gear oil pump works, oil chamber is filled with high pressure oil, gear moves between housing and sealing devices and must maintain a certain gap between them, so that leakage is inevitable. In this paper, from structure and working principle of gear pump, the main factors influencing its leakage are spindle end gap, face clearance, radial clearance and the gap of the tooth contact surface. Taking effective measures to control the gear oil pump clearance and improve the working efficiency.

Abstract:

The marine gearbox is usually installed on a vibration isolation system in order to reduce oscillation transmitted to the ship foundation. However, researches on vibration transmission in the gear-housing system and isolation system are currently independent. With the increasing requirement of lower vibration, a coupled model needs to be built to control the vibration propagation from a view of the whole system. Considering the mesh transmission error excitation of a gear pair, a flexible gear-housing-foundation coupled impedance model is constructed in this paper, and the vibratory power flow

Today, for almost all products, the appearance is very important. Thus, for example, the appearance of universal gear reducers was not given so much attention, but today there are many very interesting solutions of shape, colour and graphic design. It should have in mind that universal gear reducers have much complex construction comparing them with special gear reducers. In the same time, they have to provide different positions and way of mounting and different speeds with different powers (torques) at the output shaft. Particularly, it should be noticed, that within all universal gear reduc

Abstract:

Gears with eccentric cycloidal engagement have large gear ratios, small overall dimensions, low noise and vibration levels. A relatively low efficiency factor limits their use in transmissions mechanisms, where involute gearing with gear ratios up to 10 and high efficiency (over 0.98) are in demand. The power losses of the eccentric cycloidal engagement are caused by friction in the jointly working kinematic pairs, which are formed by the gear with at least half of the pins, and the latter form the pairs with axles or sockets in the housing. It is possible to reduce the power loss by reducing

Tooth modification is critical when designing high-performance gear transmission systems. However, it is difficult to accurately calculate the system deformation and tooth modification amount using the traditional empirical formula. Although the finite element method provides accurate results, it is time consuming and its direct application to tooth modification for multistage geared systems is difficult. This study proposes a novel methodology to define tooth modification in both width and profile directions, which can be used for multistage spur gears. First, a housing-transmission coupled d

The calculation results obtained show that the most representative three points of the peak of SPL (sound pressure level) are 500Hz, 1200Hz and 1950Hz; total SPL is 108.99dB; the main sources of the noise of the diesel engine are oi

The gear transmission system of a high-speed train is the key component, which delivers the traction torque from the motor to the wheelset. It couples with the vehicle system via the suspension system, gear meshing and the wheel–rail interface. The dynamic performance of the transmission system directly affects the operational reliability or even the running safety of high-speed trains. In this study, the effects of wheel polygonalisation and wheel flat on the dynamic responses of the transmission system are investigated through simulations of a novel vehicle dynamics model.
