Gear transmission device is an important component widely used in mechanical equipment. Today, with the rapid development of industrial production, the volume of industrial gear device is smaller and smaller, the power is larger and larger, and the operating conditions are more and more harsh. Therefore, gear lubrication has become one of the key technologies of gear transmission. The advanced industrial countries in the world attach great importance to the research and application of tribology, fully realize the importance of gear lubrication, and make a lot of scientific exploration in gear lubrication design, which greatly enriches the development of gear tribology. The specific application of gear friction in industry includes gear friction, wear and lubrication.
The relevant industry associations of the Chinese government also attach great importance to the research, promotion and application of gear tribology technology. They have successively established the China tribology society, the Development Coordination Committee of new oil products for machinery and their evaluation instruments and equipment, the gear tribology group of the gear professional committee, the gear lubrication information network, Sinopec lubricating oil science and technology information station, etc. Many colleges and universities have also opened doctoral, master’s and undergraduate courses in tribology. Many research institutions and universities also receive research projects and financial support from governments, enterprises and companies to carry out research work.
