摘要
在滚动轴承动力学基础上,建立了较大负加速条件下的圆柱滚子轴承停止阶段动力学分析模型。分析了工况参数和结构参数对圆柱滚子轴承停止阶段打滑特性的影响,并对稳态阶段的打滑特性进行了试验验证。试验结果表明:轴承在停止阶段,保持架转速随内圈转速的变化有一定时间的延后,造成保持架由正打滑变为负打滑,且其负打滑程度随着时间的变化呈现出先增大后减小的趋势。随着轴承角加速度、径向游隙和引导间隙的增大,保持架负打滑程度增大。随着径向载荷和润滑油供油温度的增大,保持架负打滑程度减小。
Based on the dynamic of rolling bearing,the dynamic analysis model of cylindrical roller bearings at stop stage under large negative acceleration was established. The influence of working conditions and structural parameters on cage slip ratio of cylindrical roller bearing was investigated at stop stage,and the test for the cage slip ratio at stable stage was carried out. The results show that there is a time delay when the rotation speed of cage changes along with the inner ring rotation speed at stop stage. The slip ratio of cage changes from positive to negative and the slip increases at first and then decreases along with time. The cage negative slip ratio increases with the increasing of angle acceleration of inner ring,radial clearance and guide clearance. There is a declining tendency of cage negative slip ratio when the radial load and supply oil temperature increase.
