Crossed Roller Bearing Inspection noise type and identification of causes

Crossed Roller Bearings abnormal sound occurred during the operation, a wide range of formation mechanism is more complex, factors that are multifaceted, and various abnormal sound often added together, it is difficult to distinguish, mainly due to the following categories:
1. The bearing inner and outer raceway presence bump hurt, scratched or periodic vibration pulse serious defect.
2. Scroll surface bump hurt of rolling bearing, aperiodic oscillation pulse scratches and other defects caused.Periodic or aperiodic oscillation pulse
3. Since residual magnetism adsorption iron powder present on the raceways or rolling elements caused.
4. impurities or dust into the bearing raceway pulse caused by aperiodic vibration. Must be done in space when high cleanliness of cross roller bearing assembly.
5. aperiodic oscillation pulse violent collision between the rolling element and spacer blocks caused.
6. poor performance lubricants, rolling vibration pulse generated when the lubricant sliding friction between the rolling element and spacer blocks and the rolling elements running. Crossed roller bearings senior grease, in order to ensure the use of sophisticated demand environment.
