摘要
针对动力传动机构四点接触球轴承的振动开展研究,建立了考虑润滑的四点接触球轴承振动分析模型,并以QJ214四点接触球轴承为例,对不同结构参数及工况参数下轴承的振动特性进行了理论分析。结果表明:四点接触球轴承径向游隙和滚动体数量越小,轴承振动越小;内、外圈沟曲率半径系数对轴承振动的影响较大,合理选择内、外圈沟曲率半径系数可以有效降低轴承振动;润滑剂可以缓和振动冲击,减小轴承的振动;对四点接触球轴承施加合理的轴向载荷可以降低轴承的振动。
The vibration of a four-point contact ball bearing for power transmission mechanism was studied. A vibration analysis model of the four-point contact ball bearing considering lubrication was established. Taking a QJ214 four-point contact ball bearing as an example, the vibration characteristics of the bearing under different structural parameters and working conditions were analyzed theoretically. Results show that the smaller the radial clearance and the number of rolling elements of the four-point contact ball bearing, the smaller the bearing vibration;the curvature radius coefficient of the inner and outer ring grooves has greater influence on bearing vibration, and a reasonable choice of the inner and outer ring groove curvature radius coefficient can effectively reduce bearing vibration;lubricant can alleviate vibration impact and reduce the vibration of the bearing;applying a reasonable axial load to the four-point contact ball bearing can reduce the vibration of the bearing.
