Problems for bearings process reference, primarily to the bearings can achieve maximum life. But these are in the process still has some shortcomings in the operation of the process. In order to prevent these defects cause great harm to the bearings. After long-term experiments and summary.
Bearing Can cancel this part of it, do not process this procedure might avoid a lot of problems. This idea is wrong. Any aspect of a step bearing in the production process are not can be omitted.
1, the installation and adjustment of the low-noise bearing grouping method to follow the long-life bearings, making more consistent with the interference size, bearing clearance is also more consistent, and you want to fit interference to the extent possible to take a smaller value in order to ensure the deformation of the bearing raceway, thereby rolling the body caused by noise becomes small.
Clearance noise, the ideal state is The clearance values exactly zero bearing the highest temperature in operation status. Judgment clearance is too large: the stationary state of the bearing axial displacement, reciprocating larger amplitude to issued a large Zhongzhuo noise running.
The running issue annoying shrill howling, the bearing preload too, bearing larger preloaded, should be slightly relaxed pretension degree of. If the clearance is too large, so that the two bearing rings axially slightly relative deviation: reduced clearance, but also increases the axial rigidity bearing noise can be reduced.
Rolling element will slip into the no-load zone or around a rocky ledge, so not only will increase the noise can also cause wear small clearance and axial stiffness to eliminate this phenomenon. But clearance can not be too small, in order to avoid overheating and shortened life expectancy.
5, sometimes due to the very large operating temperature range of the host, or the shaft and bearing bore size discrete, can not time the set to get the appropriate clearance on the outer ring of the bearing, in this case, the adoption of a flexible constant pressure preload method.
