Low noise bearing installation and adjustment
Most favorable price : sales@hellerbearings.com
Grouping method of installation and adjustment of low noise bearing could follow a long-life bearing, so that the interference fit with the same size, the clearance of the bearings are consistent, and hope that the interference to the extent possible for smaller values, to ensure deformation small bearing raceway and rolling body, the noise caused by the variable small.
Big clearance of noise, the ideal situation is when the highest temperature in the state of bearing operation, exactly zero clearance values. Judgment of excessive clearance method: static state of the shaft axial displacement, the reciprocating greatly, make a large and low noise in operation.
If running a hate the shrill whistle, the bearing preload is too large, bearings have high preload, should be slightly relaxed level of pretension. If the clearance is too large, can make two along the axial bearing rings relative deviation: reduces both clearance, and increase the axial rigidity, can reduce the bearing noise.
The rolling body into the no load zone will slip or from moving around, this would increase the noise will cause wear, small clearance and high axial stiffness can eliminate this phenomenon. But the clearance cannot be too small, so as not to cause overheating and shortened life expectancy.
Sometimes a lot because the operating temperature range of the host, or shaft and hole size very discrete, not a set would be a more appropriate clearance, in this case, the outer ring of the bearing can be made of elastic preload method.
