Coupling Effect between Gear Backlash of Friction Plate and Axial Separation Gap in Multi-Friction Pairs

Abstract:

Multi-plate friction pairs are important components in the gearbox of tracked vehicle. When the multi-friction pairs are in separation state, the uniform separation gaps of friction pairs are key factors affecting their operating performance. Most current research focuses on investigation of the failure modes of friction plate, such as, wear. However, the literatures on the vibration excitations from the inner and outer hub which affect the uniform separation gaps of the friction pairs are rare. This paper developed a rigid-flexible coupling dynamic model with different gear backlashes. The vibration characteristics of manipulate components and the separation gap of the friction pairs are studied. The results show that the model can be utilized to investigate the effects of the gear backlashes for manipulation components on the separation gaps of multi-friction pairs and it can be used to study the failure modes of friction plate in brakes. The developed model is expected to be the foundation for further optimization of the gear backlash.
