Description

Technical Field

[0001] The present application relates to the field of angular contact bearings, and in particular to a clearance calibration device for angular contact bearings. Background Art

[0002] Angular contact ball bearings mainly bear large unidirectional axial loads. The larger the contact angle, the greater the load bearing capacity. The cage material includes steel plate, brass or engineering plastics, and the molding method includes stamping or turning, which is selected according to the bearing form or use conditions. Others include combined angular contact ball bearings, double-row angular contact ball bearings and four-point contact ball bearings. Angular contact ball bearings can bear radial loads and axial loads at the same time. They can work at higher speeds. The larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. Single-row angular contact ball bearings can only bear axial loads in one direction. When bearing radial loads, additional axial forces will be caused. And the axial displacement of the shaft or housing in one direction can only be limited. If they are installed in pairs, the outer rings of a pair of bearings are opposite, that is, the wide end faces the wide end face, and the narrow end faces the narrow end face. This can avoid causing additional axial forces, and the shaft or housing can be limited to the axial clearance range in both directions.
