1. To ensure assembly quality, you can purchase or make some special tools. When disassembling and installing reducer components, try to avoid hitting them with hammers or other tools. When replacing gears, worm gears, and worm shafts, try to use original parts and replace them in pairs. When assembling the output shaft, pay attention to tolerance matching. Use anti-sticking agent or red lead oil to protect the hollow shaft and prevent wear, rust, or scale buildup on the mating surface, which would make disassembly difficult during maintenance.
2. Selection of Lubricating Oil and Additives: Helical gear-worm gear reducers generally use 220# gear oil. For reducers subjected to heavy loads, frequent starts, and harsh operating environments, some lubricating oil additives can be used. These additives ensure that the gear oil remains adhered to the gear surface when the reducer stops, forming a protective film to prevent direct metal-to-metal contact under heavy loads, low speeds, high torque, and during startup. The additives contain seal conditioners and anti-leakage agents, keeping the seals soft and elastic, effectively reducing lubricating oil leakage.
3. When selecting the installation location for the speed reducer, avoid vertical installation if possible. Vertical installation requires significantly more lubricating oil than horizontal installation, which can easily cause the speed reducer to overheat and leak oil.
4. Establish a lubrication maintenance system. Maintenance of the reducer should be carried out according to the "five fixed points" principle of lubrication work. Each reducer should have a responsible person for regular inspection. If a significant temperature rise is found, exceeding 40℃, or the oil temperature exceeds 80℃, or if the oil quality deteriorates, or if a large amount of copper powder is found in the oil, or if abnormal noise is generated, use should be stopped immediately, and timely repairs should be carried out to eliminate the fault and replace the lubricating oil. When adding oil, pay attention to the oil level to ensure...Speed ReducerGet proper lubrication.
5. New maintenance methods for gearbox wear and leakage: Traditional solutions for wear and leakage problems are welding or electroplating followed by machining. However, both have certain drawbacks: the thermal stress generated by high temperature during welding cannot be completely eliminated, which can easily cause material damage and lead to bending or breakage of parts; while electroplating is limited by the coating thickness and is prone to peeling. Moreover, both of these methods use metal to repair metal, which cannot change the "hard-to-hard" fit. Under the combined action of various forces, wear will still occur again.
