Abnormal phenomenon of bearing

Metal noise

Reason 1: abnormal load, countermeasures: modified with research, linear ball 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 sealingcontact 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 sealingdevice, 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 andbearing 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.

Abnormal temperature rise

Reason 1: excessive lubricant, countermeasures: reducing lubricant grease, proper use, select the hard.

2 reasons: lack of lubricant or not suitable, countermeasures: add lubricant, select the appropriate lubricant.

Reason 3: abnormal load, countermeasures: modify the coordination, clearance of double direction thrust ball bearing‍ pre load, adjust, modify the shoulder position of the shell.

Reason 4: poor installation, countermeasures: improve machining precision, and shell axis installation accuracy, installation method.

Reason 5: surface creep, seal friction is too large, countermeasures: replacement of bearings, study, modify the shaft and housing, changes the sealing form.

Vibration (axial runout)

Reasons: (1 Steel Carburized) surface deformation, countermeasures: Note bearing replacement operation.

Reason 2: peel, countermeasures: replacement of bearings.

Reason 3: poor installation, countermeasures: axis, shell shoulder pad angle, sideangle.

Reason 4: foreign intrusion, countermeasures: replacement of bearings, cleaningparts, improved sealing device.

Lubricant leakage is overmuch, discoloration

Cause: excessive lubricant, foreign intrusion, wear powder foreign body,countermeasures: proper use of lubricant, change the selection of lubricant, the replacement of bearings, cleaning shell.‍
