What is bearing chamfer, the role of bearing chamfer

Chamfering is a term in mechanical engineering. In order to remove burrs caused by machining on parts and facilitate parts assembly, chamfering is generally made at the end of parts. Chamfering can be seen everywhere on our life, mobile phone frame, toughened door, vase and so on.

The general purpose of chamfering is to remove burrs and make them beautiful. But for the chamfer specifically pointed out in the drawings, it is generally the requirements of the installation process, such as the installation guide of bearings, and some arc chamfer (or arc transition) can also play a role in reducing stress concentration and strengthening the strength of shaft parts. In addition, assembly can be made easy, generally before the end of the processing.

In agricultural machinery parts, especially round accessories and round hole end face is often processed into about 45° chamfer. These chamfer has many functions, in the maintenance operation must be carefully checked, and make full use of, otherwise it will bring many difficulties to the maintenance of agricultural machinery, and even cause unexpected failure. Such as bolts and other small parts before the molding process, will also be chamfered, in order to facilitate the material into the molding die.

What is the function of bearing chamfer

1. Bearing steel must be chamfered when roughing before heat treatment, so that during heat treatment of materials, stress release, internal organizational structure redistribution, crack is not easy to appear, and deformation reduction are very important. Chamfering can solve the problem of stress concentration.

2, chamfering deburring, so that the product is not sharp, will not cut the user

3. It plays a guiding and positioning role when assembling.

Usually, the outer chamfer of the bearing ring and the inner chamfer of the inner ring are rounded. In addition to effectively avoiding contact stress, the most important thing is convenient installation. Rounded corners ensure good transitional loading.

Especially in the bearing process, the matching shaft and shaft hole positioning surface, 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.
