[0002] The transmission reduction gear is a gear assembly used for deceleration in the transmission. In the automobile transmission, the reduction gear is usually composed of one or more pairs of gears, which are used to reduce the speed of the engine output and increase the torque. The reduction gear is generally made of high-strength metal materials to ensure its durability and ability to withstand high torque. They usually adopt the meshing principle of gears to transmit power through the meshing between gears. The transmission reduction gear is a gear assembly used to reduce the engine speed and increase the torque in the transmission. It plays an important role in the power transmission system of the automobile.

[0003] When the differential main reduction gear in the transmission rotates, the resistance of the lubricating oil in the transmission directly affects the transmission efficiency of the transmission. A large amount of heat will be generated during the use of the transmission. Usually, the bottom of the reduction gear will be located below the lubricating oil level inside the transmission, which is used to dissipate heat and protect the reduction gear set. However, due to the large resistance generated by the lubricating oil during the operation of the reduction gear, serious kinetic energy loss will occur. Therefore, it is urgent to solve the above problems. Utility Model Content
