Bearing noise
New running bearings is slight operation noise, the noise is to press decibels.bearing corp The causes of the rolling bearing noise is complex
The main reason
One is bea ring inner and outer uneven surface. Produce bearing noise.
Due to improper installation the force bearing noise produced uneven.
Thirdly because ball diameter not divide evenly, and caused friction inside and outside circle bearing noise.
Bearing noise essence as follows:
1, the rolling bearing way voice and control method is rolling say when running bearings, the roller on the way in rolling rolling sends out one kind of gliding continuous voice,spherical roller bearing is rolling bearings can happen all the basic characteristic of sound. The general is rolling bearing sound is way voice and other sound.
2, the rolling bearings rolling sound and control method is run over with rolling cylindrical roller bearing in all cases it could have happened to harsh metal friction sound, occurs mostly in the larger type bearing grease lubrication, and in the perfor mance degradation of oil complexes are more likely to happen, in oil lubrication almost does not occur.
3 and the impact of the roller sound and control method of the larger type ball bearings or cylindrical roller bearing in pure radial load when a low speed, because of the roller centrifugal force is small, the load in the rolling body will impact maintains a or groove and making noise.ball roller bearing
