AXIAL CLEARANCE MEASURING GAGE FOR ANGULAR CONTACT BALL BEARING

WIPO Patent Application WO/2021/258433

A1

An axial clearance measuring gage for an angular contact ball bearing, the measuring gage comprising a base, a fixing device and a measuring device. The base is provided with at least one group of grooves, with one of the grooves being provided with an anti-rotation boss (14). The fixing device comprises a bearing seat (21), a series shaft (26), an outer ring pressing plate (28), an inner ring pressing plate (25) and a pressing plate locking device (26). The measuring device comprises a dial indicator (33), a supporting rod (31), a clamping rod (32), an adjusting device (34) and a locking device (35), with the measuring device being coupled to the bearing seat (21) of the fixing device by means of the supporting rod (31). The measuring gage is simple to operate, and can integrally measure an integral clearance value of a paired angular contact bearing, thereby saving on the measurement time, improving the working efficiency, dispensing with complex conversion, and being accurate in terms of the measuring result.
