Abstract

The invention discloses a high-performance abrasion-resistant bearing and a manufacturing technology thereof. The high-performance abrasion-resistant bearing is made of the following raw materials of,by weight, 100 parts of chromium steel, 5 parts of magnesium powder, 6 parts of aluminum powder, 8 parts of copper powder, 5 parts of fiber glass filaments, 15 parts of epoxy resin, 8 parts of polytetrafluoroethylene, 3 parts of carbon fiber filaments, 3 parts of graphite, 0.75 part of silicon-barium-calcium, 1.5 parts of metal toughening agent and 0.75 part of curing agent. The high-performanceabrasion-resistant bearing is scientific and reasonable in structure, and safe and convenient to use; in the process of manufacturing the high-performance abrasion-resistant bearings, the epoxy resinand the fiber glass filaments are added into the raw materials, thus the bearing has extremely high strength, the tensile strength of the friction surface of the bearing is greatly improved, and the impact fatigue resistance property and the ability of the bearing to bear vibration and impact loads are greatly improved; and the fiber glass filaments and the high-strength polytetrafluoroethylene which are added into the bearing raw materials are composited with the epoxy resin so that the self-lubricating function of the bearing surface can be maintained for a long time, and the shortcomings ofthermoplastic materials are completely overcome.

Description

technical field [0001] The invention relates to the technical field of bearing production, in particular to a high-performance wear-resistant bearing and a production process thereof. Background technique [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 ...

[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
