Metal noise

Reason 1: abnormal load, countermeasures: modified with research, bearing clearance, adjustment and load, correction shell shoulder position.
Reason 2: poor installation, countermeasure: the processing precision of the shaft, housing, improve the installation accuracy, installation method.
3 reasons: lack of lubricant or not suitable, countermeasures: add lubricant, select the appropriate lubricant.
Reason 4: the rotating parts in contact, countermeasures: modify curve sealing contact part.
Regular noise
Reason 1: the foreign bodies caused by rolling surface indentation, rust or scars, countermeasure: the replacement of bearings, wash the parts, improve sealing device, the use of clean lubricant.
Reasons: (2 Steel Carburized) surface deformation, countermeasure: the replacement of bearings, pay attention to the use of.
Reason 3: the raceway surface peeling, countermeasures: replacement of bearings.
Irregular noise
Reason 1: the clearance is too large, countermeasures: research cooperation and bearing clearance, modify the pre load.
Reason 2: foreign intrusion, countermeasures: a study of replacement of bearings, wash the parts, improve sealing device, the use of clean lubricant.
Reason 3: spherical injury, peeling, countermeasures: replacement of bearings.
