Nine key bearing failure problem analysis

Bearing failure is often the case in the process of operation, so you don't have a cow. Malfunctioned, judgment and processing is the key. Today we will explain the reason of common faults of FAG bearings.
1, the bearing temperature is too high: in institutions, installation of bearing parts allowed to have a certain temperature, when the hand touch body shell, should not feel hot as normal, conversely indicates that bearing temperature is too high.
The cause of the high bearing temperature are: lubricating oil quality does not conform to the requirements or metamorphism, lubricating oil viscosity is too high; The assemble tight (inadequate clearance); Bearing assembly too tight; Bearing race in internal rotation shaft or housing; Too much load; Bearing cage or rolling body fracture, etc.
2, bearing noise: the functioning of the rolling bearing in the work to allow a slight noise, if you have any abnormal noise or excessive noise or sound, suggests that the bearing failure Type Of SKF Bearing.
Cause noise of rolling bearings: complex, 1) is bearing inner and outer surface wear. Due to this kind of wear and tear, damage the bearing and shell, bearing and shaft cooperate relationship, lead to axis deviation from the correct position, when axis at high speed movement produces sound. When the bearing fatigue, its surface metal flake, also can produce sound make bearing radial clearance increases. 2) bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. 3) bearing wear loose after kuang, maintains a looseness damage, also can produce sound bearing damage. Rolling bearings to remove check, according to the damage of bearing bearing failure and damage reasons.
