How to Improve Vibration and Noise Reduction Technology

When the inner and outer channel ripple is greater than 0.7μm, the vibration value of the bearing increases with the increase of ripple degree. A serious knock on the channel can increase the vibration by more than 4dB and even lead to abnormal sounds. Whether it is steel ball or ferrule, the waviness is produced by grinding.

Methodology for Diagnosing Ball Bearing Wear

The geometry of a ball bearing (inner and outer race diameters, ball diameter, and nuer of balls) determines a small sidebands and/or elevated random noise. Bearing wear or damage can occur and progress in an infinite variety of ways. Thus it is reasonable that the vibration Process of Elimination Whenever a bearing problem seems

An Overview of Bearing Vibration Analysis

As the bearing rotates, individual ball loads, hence elastic deflections at the rolling element raceway contacts, change to produce relative movement between the inner and outer rings. The movement takes the form of a locus which under radial load is two dimensional and contained in a radial plane whilst under misalignment it is three dimensional.
