[0002] Rolling bearings are a common type of bearings used in our lives. They are composed of four parts: inner ring, outer ring, rolling element and cage. There are many types of rolling bearings, such as deep groove ball bearings, needle roller bearings, angular contact bearings, self-aligning ball bearings, self-aligning roller bearings, thrust ball bearings, thrust self-aligning roller bearings, cylindrical roller bearings, tapered roller bearings, seated outer spherical ball bearings, etc. When these bearings are working, if the clearance is too small, the temperature of the rolling bearing will rise and it will not work properly, and the rolling element will get stuck; if the clearance is too large, the equipment will vibrate violently and the rolling bearing will make a lot of noise.

[0003] At present, most bearing clearance detection devices measure the inner and outer rings of the bearing through a dial indicator and obtain the point difference. Then, the size of the bearing clearance is determined based on the point difference. For example, a bearing clearance detection device disclosed in Chinese patent announcement No. CN220829161U, however, has a small application range because the base on the bearing clearance detection device can only position the bearing with a specified inner diameter.

[0012] Compared with the prior art, the beneficial effects of the utility model are:
