1. Ensure assembly quality. Some special tools can be purchased or self-made. When disassembling and installing reducer components, try to avoid knocking with hammers and other tools; When replacing gears, worm gears and worms, try to select original accessories and replace them in pairs; When assembling the output shaft, pay attention to the tolerance fit; Use anti sticking agent or red lead oil to protect the hollow shaft from wear, rust or scale on the mating area, which is difficult to disassemble during maintenance.

2. Establish lubrication maintenance system. The reducer can be maintained according to the "five determinations" principle of lubrication work, so that each reducer is regularly inspected by the person in charge. If the temperature rise is obvious, exceeding 40 ℃ or the oil temperature exceeds 80 ℃, the quality of the oil decreases, or more copper powder and abnormal noise are found in the oil, it shall be stopped immediately, repaired in time, eliminated and replaced with lubricating oil. When refueling, pay attention to the oil quantity to ensure that the reducer is properly lubricated.

3. Selection of lubricating oil and additives. Generally, the worm gear reducer adopts 220# gear oil. For the reducer with heavy load, frequent startup and poor service environment, some lubricating oil additives can be selected to make the gear oil still adhere to the gear surface when the reducer stops running and form a protective film to prevent direct contact between heavy load, low speed, high torque and metal during startup. The additive contains sealing ring regulator and anti leakage agent to keep the sealing ring soft and elastic and effectively reduce lubricating oil leakage.
