How to install low-noise bearings?

Low-noise bearing installation and adjustment can also follow the group method of long-life bearings, making more consistent with the size of interference, bearing clearance is also more consistent, and hope with the possible interference to take a smaller value, to ensure small deformation of roller bearings to rolling noise caused by the smaller.

Relationship between the clearance of large noise, the ideal state is when the bearing is in operation the maximum temperature condition, the value of exactly zero clearance. Clearance is too large to determine the method are: stationary for axial displacement of the shaft, the greater the magnitude of back and forth, issued in operation large Zhongzhuo noise.

If you hate running to issue shrill whistling, then too much bearing preload, bearing a larger pre-interference, it should be slightly relaxed pretension level. If the clearance is too large, can make a little two axial bearing rings relative deviation: not only reduces the clearance, but also increases the axial rigidity, can reduce the bearing noise.

Rolling into the load area will not slip around or be ran this way, will increase the noise can also cause wear and tear, and small and large axial stiffness of clearance to eliminate this phenomenon. However, clearance is not too small, so as to avoid overheating and shortened life expectancy.

Sometimes due to host a large operating temperature range, or size of the hole axis and the seat very discrete, not once it is set to be a more appropriate clearance, in this case, the outer ring of the bearing pre-elastic constant pressure compact method.
