Precautions for installation and maintenance of worm gear reducer

1. The selection of the installation location of the reducer. Where the location permits, try not to use vertical installation. In vertical installation, the amount of lubricating oil added is much more than that in horizontal installation, which may cause heat generation and oil leakage of the reducer.

2. Ensure assembly quality. Some special tools can be purchased or made by yourself. When disassembling and installing the reducer components, try to avoid hitting with other tools such as hammers; when replacing gears and worm gears, try to use original parts and replace them in pairs; when assembling the output shaft, pay attention Tolerance matching; anti-sticking agent or red lead oil should be used to protect the hollow shaft to prevent abrasion, rust, or dirt on the mating area, which is difficult to disassemble during maintenance.

3. Establish a lubrication maintenance system. The reducer can be maintained according to the "five fixed" principle of lubrication work, so that every reducer has a person responsible for regular inspections, and it is found that the temperature rise is obvious, if the temperature exceeds 40 ℃ or the oil temperature exceeds 80 ℃, the quality of the oil decreases or the oil If you find too much copper powder and produce abnormal noise, you should stop using it immediately, check and repair it in time, eliminate the fault, and replace the lubricating oil. When refueling, pay attention to the amount of oil to ensure that the reducer is properly lubricated.

4. Selection of lubricating oil and additives. Worm gear reducers generally choose 220# gear oil. For reducers with heavy loads, frequent starts, and poor use environments, some lubricating oil additives can be used to make the gear oil still adhere to the gear surface when the reducer stops running, forming a protective film , To prevent heavy load, low speed, high torque and direct contact between metals when starting. The additives contain seal ring regulator and anti-leakage agent to keep the seal ring soft and elastic and effectively reduce lubricating oil leakage.
