Abstract

In the service process of self-lubricating joint bearings, the wear of the liner leads to the gap between the inner and outer rings of the self-lubricating joint bearings. The existence of the clearance of the self-lubricating remote pair accelerates the collision between the inner and outer rings and further wear of the liner, which has a great impact on the dynamic characteristics of the self-lubricating joint bearings. In addition, the wear of the liner will also lead to the deterioration of the nonlinear characteristics of each component and reduce the stability of self-lubricating joint bearings. In order to study the effects of the wear of the self-lubricating liner on the dynamic response of the self-lubricating joint bearing, this study established the kinematic subvector model of self-lubricating joint bearing with clearance. Firstly, it modeled the collision force at the gap between the inner and outer rings by modifying the Lankarani-Nikravesh (L-N) normal contact force model and improving the Coulomb friction force model. Then, based on Newton’s second law, it established the rigid-flexible coupling dynamic equation with gap. Finally, it analyzed the dynamic characteristics of the drive system of the self-lubricating knuckle bearing with clearance under different wear amount and friction factor. And it also analyzed the nonlinear characteristics of the self-lubricating knuckle bearing by using phase diagram and Poincare mapping diagram. The results show that the dynamic behavior of the inner and outer rings of the self-lubricating joint bearing exhibits nonlinear characteristics with the increase of the wear amount of the fabric liner. When the wear amount is certain, the stability of the system is improved with the increase of the friction factor of the liner, and the occurrence of chaos is suppressed.

Key words： self-lubricating joint bearing; liner wear; rigid-flexible coupling dynamics; dynamic characteristic
