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. 1) , shaft and hole of the roundness, and retaining shoulder perpendicularity to according to the corresponding precision of bearing requirements. 2) , as well as the calculation of the rotating ring with quantity, also to accurate calculation of the fixed ring with right quantity. The rotating ring burning interference quantity within may also should be made smaller. As long as to ensure that work under the temperature of thermal expansion effect, and under the maximum speed of centrifugal force effect, not cause peristalsis or sliding on the surface of the tight fit. Fixed ring according to the size of the working load and bearing size, choose the smallest clearance fit or interference fit, too loose or too tight is unfavorable to keeping the original precise shape. 3) , bearings, such as under the condition of high speed operation and high working temperature, should pay special attention to the matching of the rotating ring is too loose, to prevent the eccentric vibration, and the matching of the fixed ring is a gap, in order to prevent the ferrule deformation and vibration under load. 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. Cause noise of rolling bearings is more complex, one is the 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. A: the service life of the bearing Bearing the next: there are some defects, if the bearing cannot reoccupy
