About the Suggestions to reduce the spherical roller bearing vibration

Some Suggestions about reducing spherical roller bearing vibration 1, two holes and one hole grinding process and channel superfinishing process, should guarantee in line at the bottom of the benchmark. 2, both inside and outside two channel filter arc chamfering, increased the technology to reduce the channel in the process of grinding arc cutting force, reduce the possibility of a fashion spherical convex block assembly, thereby reducing the likelihood of inner ring bump slot. 3, both inside and outside the assembly to change existing ring plane positioning base is same side assembly, assembly when the plane positioning is the most reasonable direction. Because each deep groove ball bearings in use has certain axial pre-tightening force, so using the vibration of the vibration meter value and the rotating precision of finished products testing shall be applicable to certain axial load. But due to the existence of radial clearance deep groove ball bearings, inner ring and outer ring has axial displacement, and the bearing Angle contact ball bearing with the same pressure contact Angle. Considering the existing assembly method finished bearing reference face away from the fact that these reasons from processing positioning reference. Therefore, internal and external ring reference face is the same assembly, so to make the processing standard of positioning, measurement standard and the use of the reference line.
