The disassembly, assembly and maintenance of worm gear reducers has always been a headache for protection personnel. In many cases, the worm gear reducer is damaged or has problems due to the failure of protection in time, and the project cannot be carried out normally. Therefore, it is still advocated that the repair personnel should be protected in time and must Protection is in place. Many people don't know where to start when inspecting worm gear reducers. We will solve your question today and make you a good technician for protecting worm gear reducers.

1. Ensure the quality of the device. Some special tools can be purchased or suppressed. When disassembling and installing the reducer components, try to avoid hitting with other tools such as hammers; when replacing gears, worm gears, and worms, try to use original parts and pair replacements; when installing output shafts, pay attention Public service cooperation; use anti-sticking agent or red lead oil to protect the hollow shaft to avoid wear, rust, or dirt on the joint area, and it is difficult to disassemble during repair

2. Establish lubrication protection guidelines. The reducer can be protected according to the "five fixed" principle of lubrication work, so that every reducer has a responsible person to check it regularly, and it is found that the temperature rise is significant, exceeding 40 ℃ or the oil temperature exceeding 80 ℃, the quality of the oil decreases or When more copper powder is found in the oil and abnormal noise is generated, the operation should be stopped immediately, and the fault should be repaired in time, and the lubricant should be replaced. When adding oil, pay attention to the amount of oil to ensure that the reducer is properly lubricated.

3. Selection of lubricants and additives. Worm gear reducers generally choose 220# gear oil. For reducers with heavy loads, frequent start-ups, and poor operating environments, some lubricant additives can be used to make the gear oil still adhere to the gear surface when the reducer is stopped. Protective film to avoid heavy load, low speed, high torque and direct contact between metals when starting. The extender contains seal ring regulator and anti-leakage agent to make the seal ring soft and elastic, effectively reducing lubricating oil leakage

4. Selection of the position of the reducer device. The reducer factory believes that vertical devices should not be used as far as possible when the location permits. In the case of a vertical device, the increase in lubricating oil is much more than that of a horizontal device, which is likely to cause heat generation and oil leakage of the reducer.

5. Clean up the external oil stains of the worm gear reducer, check the oil level of the lubricating oil, and record the release of the lubricating oil.

6. Remove the cover screws, open the cover, check the worm gear and record (position and direction).

7. After taking out the worm wheel and shaft, disassemble the worm shaft in the same way, and check the worm shaft and shaft.

8. Check the oil quality status (there is no oil, iron, impurities, deterioration, etc. for spare fault inquiries).

9. Remove the screws of the end cover of the worm gear shaft, take out the end cover, and make a record or symbol (the number of gaskets, etc.).

10. Before collapse, check the axial clearance of the worm gear and make a record.

11. Crash (in front of the cone, as a symbol) take out the box positioning pin. The deep hole positioning pin is taken out with a pin remover, and the through hole positioning pin is punched out from the small end.

12. Clean the box, worm gear and all parts.
