Control of raceway acoustic methods are: the selection of bearing low noise bearings which waviness small, carefully select the use conditions. Rolling road sound often affects the entire mechanical noise, reduce the raceway can reduce the noise of the whole machine.
Impact sound and its control method of rolling large models of ball bearings or cylindrical roller bearings under purely radial load and low speed operation, due to the centrifugal force of the rolling small, in the non load rolling will impact the holder or rolling road noise. But with the increase of rotational speed, the noise will disappear. On the rolling control method for impact sound: appropriate reduction of radial clearance, the use of reasonable structure and materials with cage bearings compliance.

A creak and control method of imported bearings creak metal friction sound cylindrical roller bearings are likely to occur in all cases of harsh, mostly in the larger models grease lubricated bearings, the grease base oil on the performance degradation in more easily, almost does not occur under oil lubrication. In addition, more vulnerable in the winter, when under purely radial load, prone to big occasions in a radial clearance, and with different model sizes, easy to occur within a specific speed range, both continuous and intermittent. The outer ring raceway special processing methods can prevent creak appears, when necessary, can choose this kind of bearing, or appropriate reduction of radial clearance of bearings, using high performance greases and improve the rigidity of bearing matching parts.
1, the bearing inner ring depends on the shaft and interference to achieve axial fixation, and has the advantages of simple structure, small size, suitable for supporting structure is fixed at both ends.
And stop washer lock, safe and reliable, suitable for high speed, heavy load situations.
4, imports of shaft bearing inner ring and shaft end ring to achieve axial fixation. Shaft end ring fixed by screws at the shaft end.
Shaft end ring fixed by screws at the shaft end. Fixed screw locking device. Suitable for shaft ends should not be cutting threads or space constrained occasions. Suitable for shaft ends should not be cutting threads or space constrained occasions.
5, rely on the radial size of holes in an adapter sleeve is compressed and the clamp on the shaft, to realize axial fixed bearing inner ring.
6, retreat clamping sleeve and the locking set with the same. But the withdrawal sleeve with a special nuts, imports the bearing convenient, suitable for larger radial load, double row spherical bearing axial load smaller on an optical axis fixed.
