What symptom does car generator bearing break?
The symptoms of broken automobile generator bearing: 1. The fracture of automobile generator bearing is a kind of metal friction sound or continuous brushing sound, or it may be hissing sound. 2. Bearing is an important part of modern machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient in the process of motion, to ensure its rotation accuracy.

1. Obvious rolling and vibration sound, indicating that the bearing clearance is too large;

2, the voice is hoarse, the tone is heavy, because the lubricant has impurities;

3. Irregular banging sound indicates that individual ball is broken or protruded;

4, whistle scream and clamping rolling sound, indicating that the bearing is seriously short of oil.

Bearing failure mainly shows two phenomena: overheating and abnormal sound.

1. During the operation of superheated motor, if the bearing temperature exceeds 95°C, it indicates that the bearing has overheated fault. The general reasons are as follows: 1. The inner ring of the bearing is too loose (through the inner circle) or too tight with the journal, and the outer ring of the bearing is too loose (through the circle) or too tight with the end cover bearing hole. In addition, due to the eccentric inner circle of the bearing cap or improper assembly, it will also increase the friction loss of the bearing; 3 The quality of the grease is not good or the amount added is too much.

2. Bearings with sound abnormity should have symmetrical sound and normal loudness in operation. The common abnormal sound and the reasons are as follows: 1 obvious rolling and vibration sound, indicating that the bearing clearance is too large; 2 voice hoarse, heavy tone, because the lubricant has impurities; 3. Irregular percussion sound, indicating individual ball rupture or out; 4 Whistling screams and clamping rolling sound, indicating that the bearing is seriously short of oil. Rolling bearing failure, usually according to the cause of the corresponding measures can be eliminated. For example, adjust the installation position and replace the grease. The quality is not good or if the bearing clearance is too large or it has been damaged, it can not be repaired generally, and can only be replaced with a new qualified product of the same type.
