Description

Dustproof bearing structure

Technical Field

The utility model relates to the field of bearing processing, in particular to a dustproof bearing structure.

Background

The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision. The structure of bearing mainly includes bearing inner race, bearing inner race and steel ball, and the bearing can correspond different structures of design according to the functional requirement of difference to dustproof bearing structure is for example, and present bearing structure mainly reaches dustproof effect through the sealing ring between bearing inner race and the bearing outer race, can discover during the in-service use, and the sealing ring has not high and the insecure problem of installation of intensity, and the leakproofness and the dustproof effect of bearing are all not good.

Disclosure of Invention

The utility model aims to solve the defects in the prior art and provides a dustproof bearing structure.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
