摘要
在角接触球轴承动力学分析基础上,结合轴承保持架的柔体性,采用修正的Craig-Bam-pton子结构模态综合法建立高速角接触球轴承保持架柔体动力学方程。利用ADAMS系统开发了角接触球轴承刚柔多体动力学分析程序,对高速角接触球轴承保持架动态性能进行了分析;并采用Gupta的角接触球轴承动力学分析结果加以验证。分析结果表明:角接触球轴承引导间隙与兜孔间隙之比、径向载荷与轴向载荷之比过大或过小都不利于保持架转动的平稳性;相对刚体保持架而言,柔体保持架转动更为平稳。
A dynamic analysis method for the flexible cage dynamic formula of high-speed angular contact ball bearing was described.The flexible cage dynamic formula of high-speed angular contact ball bearing computational formulation was established using a modified Craig-Bampton component mode synthesis method based on angular contact ball bearing dynamics analysis.The dynamic characteristics of cage of high-speed angular contact ball bearing was analyzed using rigid-flexible multi-body dynamic analysis program ADAMS,and was verified by the computation example of Gupta.The results show that the rotary smoothness of cage will be broken if the ratio of pocket clearance to guided clearance and the ratio of radial load to axial load become too large or too small.The flexible cage runs more smoothly compared to the rigid cage.
