摘要

基于滚动轴承动力学理论,建立了弹性支承下三瓣波滚道圆柱滚子轴承动力学微分方程组,采用预估-校正变步长积分算法对其进行求解,研究了弹性支承件的结构参数和轴承工况参数对三瓣波滚道圆柱滚子轴承径向振动的影响。结果表明:弹性支承件的沟槽数、梁厚及过渡角对该轴承径向振动的影响较为显著,而沟槽间隙对其径向振动的影响较小;在一定的载荷和转速范围内,弹性支承件可有效降低轴承的径向振动,选用沟槽数较少的弹性支承件可实现在较大转速和载荷范围内降低该轴承振动的目的;在定冲击载荷范围内,弹性支承能有效降低轴承振动。

Abstract

Based on dynamics analysis of rolling bearing,the dynamics differential equations for cylindrical roller bearing with trilobe raceway and elastic support are established. By using the predict-correct integer algorithm with variable step,the dynamics equation is solved,and the influence of structural parameters of elastic support and working conditions on the vibration characteristics of the bearing is investigated. The results show,that the inter-groove number,thickness circular beam and transition angle of elastic support have significantly effect on the vibration of bearings,but gap of groove has little effect on it. In a certain range of load and rotation speed,elastic ring can effectively decrease the vibration of bearing,elastic support with lesser inter-grooves can enlarge its impact-absorb range of load and speed,the elastic support also can reduce the bearing vibration caused by the impact load.
