摘要: Manufacturing errors result in dynamic loads on gear teeth that must be accounted for in design. Such loads can be estimated from a mass/spring model that considers the operating speed, tooth stiffness, and rotating mass of the meshing gears. 被引量: 8 年份: 1984 收藏...
2.8.2 DYNAMIC TOOTH LOADS The dynamic forces on the teeth are produced by the transmitted force, and also by the velocity changes due to inaccuracies of the tooth profiles, spacing, misalignments in mounting, and tooth deflection under load. The dynamic load Fd proposed by Buckingham is Fd=0...
In this paper, the influence of the variable stiffness of mating gear teeth on dynamic loads occurring between teeth in a single-gear transmission is investigated using a discrete-continuous model consisting of two torsionally deformable ponderable shafts and four rigid bodies. The stiffness is descri...
The backlash may induce the tooth separation and impact, which gives rise to large dynamic loads and vibration problems. Fig. 11 illustrates the dimensionless backlash function in Eq. (28) and three possible impact cases [28]: (1) No impact. The tooth pair meshes normally without separation....

le errors are added to the dynamic model previously developed by the authors, with the aim of analysing the consequences on the dynamic behaviour under several torque loads. As a consequence of the supports ?exibility, the amplitude of the transmitted torque modi?es the distance between centres ...

In speed ranges where resonance takes place, relatively large amplitudes of vibration occur, potentially leading to the contact loss with high dynamic contact loads. In traditional gear dynamic analysis, lumped parameter models are widely used. They assume a gear pair is composed of two rigid disks...
