In order to reduce parts wear and power loss caused by internal friction, lubricating oil should be injected into the case and the working surface of each gear pair, shaft and bearing should be lubricated by splash lubrication. Therefore, one side of the shell is provided with an oil filler and the bottom is provided with an oil drain plug. The height of the oil surface is controlled by the position of the oil filler. Radial oil holes are drilled in the first and third gear of the first and second shafts, and radial oil grooves are cut in the end face of the hub of the middle gear and the middle shaft transmission gear for lubrication of needle roller bearings in the position. In order to prevent the 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. There is a return oil groove in the inner hole of the bearing cover to prevent oil leakage. To prevent the oil from flowing out of the second shaft. An oil seal assembly is fitted in the rear bearing cover of the transmission. Seal gaskets shall be installed on the joint surface of each bearing cover, back cover, top cover, front and rear shell, etc., and sealant shall be applied to prevent oil leakage. In order to prevent oil leakage caused by oil temperature and pressure increase when the transmission is working, there is a ventilation plug on the transmission mechanism seat and the transmission rear bearing cover.
