大型深沟球轴承径向游隙的测量

Measurement on radial clearance of large deep groove ball bearing

大型深沟球轴承外形尺寸大、质量重,其径向游隙在现有仪器上无法得到准确的测量。根据该类轴承的特点与国家标准,对现有测量仪器进行了改进,设计了加载装置,使轴承按照规定的加载量进行加载,保证了径向游隙的准确测值。此种测试方法使用方便、测量效率高。

With the features of large size and great weight, the radial clearance of large deep groove ball bearing couldn’t be measured accurately with current instrument. According to the features of this bearing and national standard, the current instrument was improved. The design of a loading device made bearing be loaded under stipulated loading amount, so that accurate measurement of radial clearance was guaranteed. This measuring method was convenient in use and efifcient.
