In operation, the source of the track noise is due to the natural vibration of the ferrule after the load is applied. The elastic contact between the ferrule and the rolling element constitutes a nonlinear vibration system. When the lubrication or processing accuracy is not high when it will stimulate the elastic characteristics of the inherent vibration, transmitted to the air becomes noise.
First, deep groove ball bearings by external excitation caused by the inherent vibration of deep groove ball bearings, deep groove ball bearings that inner ring, outer ring, rolling body and the cage of the inherent vibration.
The second is due to contact with each other moving parts of the collision caused by forced vibration, including the rolling body is not an ideal sphere, the internal and external channel contact point movement trajectory is not an ideal circle (roundness, waviness), rolling surface is not the ideal smooth surface Roughness) as well as the rolling element and the cage in the movement of the collision and impurities in the lubricant caused by forced vibration, vibration and sound are closely related.
