【摘要】 为提高角接触球轴承接触角的测量精度,研制了一台能够稳定加载、动力传动链短,精度高且拥有自校准功能的轴承接触角测量仪,并介绍了测量仪的结构组成和基于PLC的测控系统。重复性试验及不同加载工况下的试验结果表明,该球轴承接触角测量仪运行稳定可靠,满足接触角不大于0.5°的设计精度要求。更多还原

【Abstract】 In order to improve measuring accuracy of contact angle of angular contact ball bearings, a measuring instrument for contact angle of the bearings with stable loading, short power transmission chain, high accuracy and self-calibration function is developed. The structural composition and measurement and control system based on PLC of measuring instrument are introduced. The repeatability test and test results under different loading conditions show that the instrument runs stably and reliably, and the design accuracy of contact angle is not higher than 0.5 degrees.更多还原
