摘要
自润滑关节轴承轴向与径向均可以加载和摆动,衬垫接触面上的摩擦应力是复杂多变的,且在不同的工况下的摩擦力矩的变化较大,摩擦力矩一方面会使轴承发热和磨损;另一方面又确保了轴承在运动过程中的稳定。本文通过有限元分析软件Workbench建立模型模拟关节轴承的实际工况,提出使用Workbench计算关节轴承摩擦力矩的方法,目的是为了能够更好地保护关节轴承,提升关节轴承的效率和质量。
The self-lubricating spherical plain bearing can be loaded and swayed in both axial and radial directions.The friction stress on the contact surface of the bearing is complex and changeable,and the friction torque changes greatly under different working conditions.On the one hand,the friction torque will make the bearing heat and wear,on the other hand,it ensures the stability of the bearing movement process.In this paper,the finite element analysis software Workbench is used to establish a model to simulate the actual working conditions of the spherical plain bearing,and a method to calculate the friction torque of the spherical plain bearing by using Workbench is proposed.The purpose is to better protect the spherical plain bearing and improve the efficiency and quality of the spherical plain bearing.
