轴承零件的摩擦力矩实测比较困难,为探究滚滑轴承摩擦力矩的变化规律及结构参数对其的影响,指导该新型轴承的结构设计,利用Abaqus软件对滚滑轴承进行了仿真分析。结果表明,滚滑轴承摩擦力矩呈现由小到大、再到小、最后进入稳定的变化规律;启动时,滚滑轴承摩擦力矩随径向游隙增大而增大、随滚子与滑块间的间隙增大而减小,滑块与内圈间的摩擦力矩随滑块内弧半径增大而增大,滑块与外圈间的摩擦力矩随滑块外弧半径增大而减小; 进入稳定运动后,滚滑轴承摩擦力矩随径向游隙及滚子与滑块间的间隙增大而减小,滑块与内圈间的摩擦力矩随滑块内弧半径增大而增大,滑块与外圈间的摩擦力矩随滑块外弧半径增大而减小。
It is difficult to measure the friction torque of bearing parts in practice. In order to study the variation law of the friction torque of rolling-sliding bearings and the influence of the structure parameters on it, the simulation analysis of rolling-sliding bearings is carried out by using Abaqus software to guide the structural design of the new bearing. The results show that the friction torque of the rolling-sliding bearing is from small to big, then to small, finally to stable. And the starting friction torque of the rolling-sliding bearing increases with the increase of the radial clearance and decreases with the increase of the clearance between the roller and the slider, the starting friction torque between the slider and the inner ring increases with the increase of the inner arc radius of the slider, the starting friction torque between the slider and the outer ring decreases with the increase of the outer arc radius of the slider. And after stable motion, the friction torque of the rolling-sliding bearing decreases with the increase of the radial clearance and the clearance between the roller and the slider, and the friction torque between the slider and the inner ring increases with the increase of the inner arc radius of the slider, and the friction torque between the slider and the outer ring decreases with the increase of the outer arc radius of the slider.
