In order to reduce component wear and power loss caused by internal friction, lubricating oil must be injected into the housing and splash lubrication should be used to lubricate the working surfaces of various gear pairs, shafts, bearings, and other components. Therefore, there is a fuel filling port on one side of the shell and a drain plug at the bottom, and the oil level is controlled by the position of the fuel filling port. Radial oil holes are drilled on the first and third gears of the first and second shafts, and radial oil grooves are opened on the hub end faces of the reverse intermediate gear and the intermediate shaft constant meshing transmission gear to lubricate the needle roller bearings in their respective areas. To prevent lubricating oil from flowing into the clutch through the gap between the first shaft and the bearing cover and affecting its friction performance, an oil seal assembly is installed inside the bearing cover. There is an oil return groove in the inner hole of the bearing cover to prevent oil leakage. To prevent lubricating oil from flowing out from the rear end of the second shaft. An oil seal assembly is installed inside the rear bearing cover of the transmission. Install sealing gaskets at the joint surfaces of each bearing cover, rear cover, upper cover, front and rear shells, and apply sealant to prevent oil leakage. To prevent lubricating oil leakage caused by increased oil temperature and pressure during transmission operation, ventilation plugs are installed on the transmission mechanism seat and the rear bearing cover of the transmission.
