Description

Flange type double-row angular contact bearing

Technical Field

The utility model relates to a bearing technical field specifically is a flange formula double row angular contact bearing.

Background

Angular contact ball bearings can simultaneously withstand both radial and axial loads. Can work at higher rotating speed. The larger the contact angle, the higher the axial load capacity. High precision and high speed bearings typically take a 15 degree contact angle. Under axial force, the contact angle increases. The single-row angular contact ball bearing can only bear axial load in one direction, and when bearing radial load, additional axial force is caused. And can only limit axial displacement of the shaft or housing in one direction. If the bearings are installed in pairs in a duplex way, the outer rings of the pair of bearings are opposite, namely the wide end faces face the wide end faces, and the narrow end faces face the narrow end faces. This avoids the need to introduce additional axial forces and limits the shaft or housing to within axial play in both directions. Most of the prior art have the defect of complex installation, and the clearance needs to be adapted in the later period.
