How to minimize the noise of tapered roller bearings?

Bearing is essential for mechanical operation, but bearing also has its own shortcomings that can not be overcome. Bearing is one of the sound sources of mechanical noise. So how do we minimize the noise of tapered roller bearings?
Discussing the mechanism of bearing noise and studying the comprehensive control in the production process are the key to improve bearing quality and realize technological innovation. Compared with other types of products, the structure, performance and noise generation mechanism of tapered roller bearings are very special.
The bearing will inevitably produce vibration during operation. On the one hand, vibration is caused by external factors. It can be seen that the key to solve the problem of bearing noise is to solve the vibration of bearing.
Firstly, the dimensional accuracy, shape position accuracy and surface quality of each bearing part shall meet the technical conditions of corresponding accuracy level; Find out the main noise sources and focus on solving them in the processing process.
When the bearing rotates, the cage is free floating. In order to reduce the string momentum of cage, the length of window hole shall be produced according to the deviation size. At the same time, in order to reduce the friction sound between cage and roller, it is necessary to carry out surface string light and phosphating treatment. In addition, when retracting the cage, tighten it as much as possible without affecting the rotation flexibility of the bearing.
During the processing, inspection, assembly, storage and transportation of bearing parts and finished products, the operating procedures shall be strictly observed to avoid adverse consequences such as bumping, deformation and corrosion. At the same time, the finished products after assembly must be fully cleaned to completely remove dust and adhesion to ensure cleanliness.
