轴承滚子不平衡量测试方法

摘要

针对轴承滚子质量小、不平衡量小、驱动难度大的特点，提出了采用激光在共振区测量滚子不平衡量的方法，很好地解决了依据不平衡量分检滚子的问题。建立了摆架的动力学模型，对摆架动力学特性进行了分析。并设计了测试系统，对该方案的可行性进行了验证。%Aiming at the characteristics of tiny mass,small unbalance and driving difficulty of bearing rollers,the laser detecting method for unbalance of rollers is introduced in the resonating region.The problem is well solved about sorting of roller according to unbalance.The dynamic model of frame structure is built,and dynamic characteristic of the frame structure is analyzed.The detecting system is designed,and the feasibility of the scheme is verified.
