Transmission gears are important components of automotive engines for changing the speed ratio of the engine crankshaft and the driveshaft. In the working process of the gear of the gearbox, power is transmitted through the contact of the tooth surfaces, and the two tooth surfaces roll and slide in the meshing contact process, so that larger pressure stress and friction force exist. However, during the meshing contact of the tooth surfaces of two meshing gears, especially in the high-speed heavy-duty gear transmission of a gearbox, the temperature of the meshing area is high due to the large friction force between the meshing tooth surfaces and the high relative speed. Generally, lubricating oil is coated on the gear, so that an oil film is formed between tooth surfaces, and abrasion is reduced. However, the friction between the tooth surfaces of the gears causes the temperature to be too high, the lubricating oil is easy to deteriorate, the gears cannot be lubricated, and the abrasion between the tooth surfaces is more serious. In addition, when a plurality of automobile gears are mounted on the same shaft, particularly when two gears are attached together, heat is generated between the gears due to the coaxial rotation of the gears, and therefore, the lubricating oil for lubricating the gears is deteriorated if the heat is not dissipated. There is a need to find a new solution to solve the above problems.
