What is the bearing chamfer, bearing chamfer

What is the bearing chamfer? As shown, chamfering is mechanical engineering terms, in order to remove the parts because of the machining burrs, also in order to facilitate part assembly, generally make chamfer at the end of the parts. We live on the chamfer everywhere, mobile phone shell, steel doors, vases, etc. General chamfering is used to remove burrs, make it beautiful. But for drawings chamfer, points out that in general the requirement is the installation process, such as bearing installation guide, there are some circular chamfering ( Or called arc transition) Also can rise to reduce stress concentration, to strengthen the role of the strength of the shaft parts. In addition, you can make it easy to assemble, generally before the end of the process. On the agricultural machinery parts, especially the circular parts and round hole of the end face often processing of about 45 ° chamfer. The chamfering has various functions, during the maintenance operations must be carefully check, and fully take advantage of, otherwise it will bring many difficulties to agricultural machinery maintenance, even cause unexpected failure. Before such as bolts and other small parts molding process, also will undertake chamfering, in order to convenient material into the forming die. What role does the bearing chamfer 1, bearing steel during heat treatment before rough machining, there must be a chamfer, so for the material of heat treatment, stress release, redistribute, internal organization structure is not easy to appear crack, reduce the deformation is a very important role. Chamfering can solve the problem of stress concentration. 2, chamfering, deburring, make the product is not sharp, not cut the user guide positioning at the time of the 3, the assembly. Usually bearing outer ring of the outer and inner ring chamfer within chamfering are rounded, in addition to effective avoid contact stress of the main is convenient for installation. Rounded corners can guarantee good transitional loading. Especially in the process of the bearing, match the positioning surface of the shaft and the shaft hole, namely shoulder and bearing block shoulder part, this part of the chamfer size can directly affect the bearing installed correctly. From above we can see that the bearing load between shaft and axle box, its chamfer all than bearing housing and shaft shoulder of chamfering, bearing chamfer must be bigger than the arc to ensure the bearing joint axial positioning surface. As shown in the above when bearing chamfer is less than the bearing housing and shaft shoulder chamfering, unable to assembly in place, easy to cause the bearing chamfer stress concentration, the assembly tilt, cooperate with other parts can't match and a series of problems.
