Although the cage slip of cylindrical roller bearings has been measured and studied experimentally, it is difficult to use current experimental measurement to detect the cage slip of the bearing in actual service or engineering environment. The problem is attributed to the limit on the space for current test instruments that can be installed arbitrarily in laboratory, but not in actual environment. A novel measurement based on strain detection is presented. This measurement can be used to obtain the cage slip of the bearing in service or large bench test. The technique is demonstrated and validated in principle by an experimental system. The system is developed to obtain the strain signal of the outer ring in loaded zone as well as the speed signal of the cage and the inner ring at the same time. Under given test load–speed conditions, the cage slip based on strain detection was compared with the cage slip based on speed detection. Experimental results showed that cage slip ratio curves based on strain responses agreed very well with those based on speed signals. In this way, it is revealed that frequency characteristics of strain signals can be used to obtain internal cage slip of cylindrical roller bearings.

圆柱滚子轴承保持架滑移测量实验系统的研制

虽然已经对圆柱滚子轴承的保持架滑移进行了实验测量和研究，但在实际使用或工程环境中，很难用目前的实验测量来检测轴承的保持架滑移。问题归结于当前测试仪器的空间限制，可以在实验室中任意安装，而不能在实际环境中安装。提出了一种基于应变检测的新型测量方法。该测量可用于获得轴承在使用中或大型台架试验中的保持架滑移。该技术在原理上通过实验系统进行演示和验证。该系统的开发是为了同时获取外圈载荷区的应变信号以及保持架和内圈的速度信号。在给定的试验负载-速度条件下，将基于应变检测的保持架滑动与基于速度检测的保持架滑动进行了比较。实验结果表明，基于应变响应的笼子滑移率曲线与基于速度信号的曲线非常吻合。这样，揭示了应变信号的频率特性可用于获得圆柱滚子轴承的内部保持架滑移。
