Bearings are essential for mechanical operation, but bearings also have their own insurmountable shortcomings. Bearings are one of the 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 improving bearing quality and realizing technological innovation. Compared with other types of products, the structure, performance and noise generation mechanism of tapered roller bearings are very special. Bearings inevitably vibrate during operation. Vibrations are on the one hand caused by external factors. It can be seen that the key to solving the problem of bearing noise is to solve the vibration of the bearing. First of all, the dimensional accuracy, shape position accuracy, and surface quality of each part of the bearing should meet the technical conditions of the corresponding accuracy level; find out the main source of noise, and focus on solving it during the processing. When the bearing rotates, the cage is in a free-floating state. In order to reduce the amount of string movement of the cage, the length of the window hole should be produced according to the deviation size. At the same time, in order to reduce the friction sound between the cage and the rollers, surface cross-lighting and phosphating treatment must be carried out. In addition, when shrinking the cage, it should be tightened 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, operating procedures should be strictly followed to avoid adverse consequences such as bumps, deformation, and corrosion. At the same time, the finished product after assembly must be fully cleaned to completely remove dust and adherents to ensure cleanliness.
