Solutions to common problems of helical gear reducer

Author : Site EditorPublish Time :

1. Guarantee assembly quality
You can buy or make some special tools. When disassembling and installing the parts of the reducer, try to avoid hitting with other tools such as hammers; when replacing gears, worm gears, and worms, try to use original parts and replace them in pairs. Pay attention to tolerance coordination; use anti-sticking agent or red lead oil to protect the hollow shaft to prevent abrasion, rust, or dirt on the mating area, which is difficult to disassemble during maintenance.

2. Selection of lubricants and additives
Helical gear-worm gear reducers generally choose 220# gear oil. For reducers with heavy loads, frequent starts, and poor use environments, you can choose some lubricant additives to make the gear oil still adhere to the gear surface when the reducer stops running . Form a protective film. Prevent heavy load, low speed, high torque and direct contact between metals when starting. The additives contain seal ring regulator and anti-leakage agent. The seal ring is used to maintain softness and elasticity and effectively reduce lubricating oil leakage.

3. Selection of the installation location of the reducer
Where the location permits, try not to use vertical installation. For vertical installation, the amount of lubricant needs to be added much more than for horizontal installation. It is easy to cause heat and oil leakage of the reducer.

4. Establish a lubrication maintenance system
The reducer can be maintained according to the "five fixed" principle of lubrication work, so that every reducer has the person responsible for regular inspections, and it is found that the temperature rise is obvious, if the temperature exceeds 40°C or the oil temperature exceeds 80°C, the quality of the oil decreases or the oil If more copper powder and abnormal production noise are found, stop using it immediately, overhaul it in time, eliminate the fault, and replace the lubricant. When refueling, pay attention to the amount of oil to ensure that the accelerator is properly lubricated.

5. Methods of maintenance in the new period
For the wear and leakage of the reducer, the traditional solution is repair welding or machining and repairing after brush plating, but both have certain drawbacks: the thermal stress of repair welding at high temperature cannot be completely eliminated, and it is easy to cause material damage and cause parts to play. The brush plating is limited by the thickness of the coating, it is easy to peel off, and the above two methods use metal to repair the metal, which cannot change the "hard to hard" coordination relationship. Under the combined action of various forces, it will still cause Worn again. Contemporary Western countries mostly use polymer composite repair methods for the above problems.
