Chamfering is a term in mechanical engineering. In order to remove the burrs on the parts due to machining, and also to facilitate the assembly of the parts, chamfers are generally made at the ends of the parts. In fact, chamfering can be seen everywhere in our lives, such as on the frame of mobile phones, on tempered doors, on vases and so on.

Generally, the function of chamfering is to remove burrs and make them beautiful. However, for the chamfering specified in the drawing, it is generally a requirement of the installation process, such as the installation guide of the bearing, and some arc chamfers (or arc transitions) can also reduce stress concentration and strengthen shafts. The effect of the strength of the part. In addition, assembly can be facilitated, generally before the end of processing.

On agricultural machinery parts, especially the end faces of round fittings and round holes are often processed into chamfers of about 45°. These chamfers have various functions, and must be carefully checked and fully utilized during maintenance operations, otherwise it will bring many difficulties to agricultural machinery maintenance and even cause unexpected failures. For example, before the forming process of small parts such as bolts, chamfering is also performed, so that the material can easily enter the forming die.

What is the function of bearing chamfer

1. Bearing steel must be chamfered during rough machining before heat treatment, so that when the material is heat treated, the stress is released, the internal structure is redistributed, cracks are not easy to appear, and deformation is reduced. It has a very important role. Chamfering can solve the problem of stress concentration.

2. Chamfer and deburr, so that the product is not sharp and will not cut the user.

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

Usually, the outer chamfer of the outer ring and the inner chamfer of the inner ring are rounded. In addition to effectively avoiding contact stress, the most important thing is to facilitate installation. Rounded corners 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 correctly installed in place.
