摘要:阐述了滚动体接触区载荷分布与应力变化趋势对轴承寿命及可靠性影响的重要性,分析了滚动轴承接触力计算与试验研究进展。为了给轴承滚子优化设计提供依据,设计了一种以数字散斑相关方法(DSCM)为依据的测量系统,包括滚子定位装置、加载装置和数据采集、处理系统。对某滚子试样进行接触力检测,得到了不同载荷条件下滚子应变分布,为轴承接触力分布检测提供了新方法。

Abstract:Load and stress distribution of rolling element on contact area is important influence on life and reliability of bear and the calculation and test research progress of contact force are analyzed systematically, a new method of rolling bearing contact force detection is provided. In order to provide the basis for the optimal design of bearing roller, a measurement system based on digital speckle method was designed, including roller positioning device, loading device and data acquisition and processing system. The strain distribution under different load conditions is obtained by the contact force test of a roller sample, and a new method is provided for bearing contact force distribution detection.
Key words:rolling element;bear;DSCM
