Prevent INA cylindrical roller bearing configuration malfunction need attention

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. Installed in institutions, there is the part of the cylindrical roller bearing 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) ; INA 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 request according to the corresponding precision of cylindrical roller bearing. 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) , INA bearings, such as under the condition of high speed running, and working temperature is higher, 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 INA bearing inner and outer surface wear. Due to this kind of wear and tear, damage the bearings, cylindrical roller bearings with shell and the 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. In addition, the bearing lubrication, form dry
