摘要

基于滚动轴承动力学理论，建立了弹性支承下高速圆柱滚子轴承动力学微分方程组，采用预估-校正Gear stiff (GSTIFF)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、梁厚及过渡角对轴承径向振动的影响较为显著，而沟槽间隙对圆柱滚子轴承径向振动的影响较小，合理的选择弹性支承件的结构参数可有效的降低高速圆柱滚子轴承的径向振动；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圆柱轴承振动的目的。

Abstract

Based on dynamic analysis of rolling bearing, dynamic differential equations for high-speed cylindrical roller bearing with elastic support were established. Predict-correct Gear stiff(GSTIFF) integer algorithm with variable step was applied to solve the dynamic equations, and the influence of structural parameters of elastic ring support and working conditions on the vibration characteristics of cylindrical roller bearing was investigated. The results show: 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. Choosing parameters of elastic support reasonably can reduce the radial vibration of rolling bearing effectively. In a certain range of load and revolving speed, elastic ring can effectively decrease the vibration of bearing and elastic support with lesser inter-grooves can enlarge its impact-absorb range of load and speed.
