After the worm gear reducer is used for a long time, oil leakage, mechanical aging and other phenomena will occur, so it needs to be maintained and maintained during use. So how to maintain it? This article introduces the assembly quality, lubrication maintenance, and selection of lubricants and additives of the worm gear reducer, and explains the maintenance methods of the worm gear reducer. To ensure the assembly quality of the worm gear reducer, you can purchase or make your own special tools.
When disassembling and installing reducer parts, try to avoid hitting them with hammers and other tools; when replacing gears and worm gears, try to use original parts 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 to prevent wear and rust or scale on the mating area, making it difficult to disassemble during maintenance.
Establish a lubrication maintenance system to maintain the reducer according to the "five certain" principles of lubrication work, so that each reducer has a responsible person to check it regularly. If it is found that the temperature rise is obvious, exceeding 40°C or the oil temperature exceeds 80°C, the oil When the quality of the oil decreases or a large amount of copper powder is found in the oil or abnormal noise is produced, stop using it immediately, conduct timely maintenance, eliminate faults, and replace the lubricating oil. When refueling, pay attention to the amount of oil to ensure that the reducer is properly lubricated. Selection of lubricating oil and additives:
Worm gear reducers generally use 220# gear oil. For reducers with heavy loads, frequent starts, and poor use environments, some lubricating oil additives can be used to keep the gear oil still attached when the reducer stops running. A protective film is formed on the gear surface to prevent direct metal-to-metal contact during heavy loads, low speeds, high torques and startup. The additive contains sealing ring regulator and anti-leakage agent to keep the sealing ring soft and elastic, effectively reducing lubricating oil leakage.
