1. Wound sound and its control method
Rolling bearings of rolling surface, indentation, or if there is a crack corrosion, will appear like rivet rivet regularity of vibration and noise, the cycle time may be fixed but most, the corresponding relationship between rotating speed into the corresponding scars on the channel will continue to appear, scars on the ball, and the noise with the installation and lubrication standard and have corresponding changes. The control measures of this kind of noise are as follows: the bearing can not be knocked during installation, and the bearing and shaft can be installed and then installed into the bearing housing to avoid bearing installation skew; Avoid bearing corrosion during inventory and avoid impact vibration during transportation; Apply grease with high viscosity.
2.Dust sound and its control method
The control measures of dust sound include: improving the cleaning method of bearings, strictly cleaning bearings, shafts, seat holes and their matching parts before installation; Clear the impurities in the lubricant, improve the seal of the bearing, prevent the application of impure material or embedded plastic cage.
