In order to reduce the wear and power loss of parts caused by internal friction, lubricating oil must be injected into the shell and the working surfaces of gear pairs, shafts, bearings and other parts shall be lubricated by splash lubrication. Therefore, there is an oil filler on one side of the shell, an oil drain plug at the bottom, and the oil level height is controlled by the position of the oil filler. Radial oil holes are drilled on the constant meshing gear of the first shaft and the third gear of the second shaft, and radial oil grooves are opened on the hub end face of the reverse intermediate gear and the intermediate shaft constant meshing transmission gear to lubricate the needle roller bearing at the position. In order to prevent lubricating oil from flowing into the clutch from the gap between the first shaft and the bearing cover and affecting its friction performance, an oil seal assembly is installed in the bearing cover, and 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 in 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 housings, and apply sealant to prevent oil leakage. In order to prevent the leakage of lubricating oil due to the increase of oil temperature and pressure during the operation of the transmission, a vent plug is installed on the transmission mechanism seat and the rear bearing cover of the transmission.
