Why Rubber Bushing needs chamfering process?

Chamfering is a term in mechanical engineering. In order to remove the burrs caused by machining on the parts and to facilitate the assembly of the parts, chamfers are generally made at the ends of the parts. 

What is the function of chamfering?

1. The bearing steel must be chamfered during rough machining before heat treatment, so that during the heat treatment of the material, the stress is released, the internal structure is redistributed, cracks are not easy to appear, and deformation is reduced. Chamfering can solve the problem of stress concentration.

2. Chamfering and deburring make the product not sharp and will not cut the user.

3. It plays a role of guiding and positioning during assembly.

Generally, the outer chamfer of the outer tube and the inner chamfer of the inner tube of the bushings are rounded corners. In addition to effectively avoiding contact stress, the most important thing is to facilitate installation. The rounded corners can ensure a good transitional fit.

Especially in the bearing process, the matching shaft and the positioning surface of the shaft hole, that is, the shaft shoulder and the bearing seat shoulder part, the chamfer size of this part directly affects whether the bearing can be installed correctly.
