Problems solved by technology

[0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. However, the existing bearings have the following problems during use Defect: During use, due to the friction between the outer ring and the inner ring, a certain amount of heat will be generated. If the heat is not dissipated in time, the service life of the bearing will be reduced. Moreover, when the bearing is connected to the valve body, if If the connection is not tight, there will be slippage, which will affect the normal operation of the butterfly valve. During use, the strength of the bearing is low. Under long-term rotation, the friction layer of the bearing will fall off, which will affect the normal use of the bearing. Moreover, After the bearing has been used for a period of time, the bearing needs to be lubricated. Otherwise, the friction force inside the bearing will increase due to long-term wear, which will reduce the service life of the bearing. During the use of traditional bearings, The anti-impact fatigue performance of the bearing, the ability of the bearing to withstand vibration and impact load are all low, and it cannot meet the harsh working conditions of high frequency and long life without lubrication. Therefore, people urgently need a new type of high-performance wear-resistant bearing and its production process to solve the above problems
