Bearing heat treatment material
1. Bearing steel needs chamfering during rough machining before heat treatment, which plays a very important role in the release of stress, redistribution of internal structure, less crack and reduction of deformation during material heat treatment. 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 guiding and positioning role during assembly.
The function of chamfering of general parts is deburring and beautiful.
However, the chamfering of the bearing is conducive to the installation and guidance of the bearing. Some arc chamfering (or called arc transition) can also reduce the stress concentration and strengthen the strength of shaft parts!
The large chamfer of bearing has nothing to do with deburring, which is mainly the assembly function. In fact, it is not only the bearing, so the parts to be assembled need to adopt this Law: the inner circle is Bearing rounded off, the large circle is rounded off, the small inner chamfer usually adopts fillet, and the outer chamfer adopts chamfer, that is, straight chamfer. Generally, the chamfer is larger than the fillet because the chamfer and the right angle should be matched. Only when the fillet is small enough can space be made at the matching place, otherwise it is easy to interfere.
