Common Problems And Solutions Of Gear Reducers、

- Dec 16, 2020-

1. Ensure assembly quality

Some special tools can be purchased or made by yourself. When disassembling and installing reducer parts, 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 to tolerance matching; anti-sticking agent or red lead oil should be used to protect the hollow shaft to prevent wear, rust, or dirt on the mating area, which is difficult to disassemble during maintenance.


2. the selection of lubricants and additives

Helical gear-worm gear reducers generally use 220# gear oil. For reducers with heavy loads, frequent starts, and poor use environments, some lubricant additives can be used to make the gear oil still adhere to the gear surface when the reducer stops running , To form 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 elastic and effectively reduce lubricating oil leakage.


3. the selection of the installation location of the reducer

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


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 will decline or if more copper powder and abnormal noise are found in the system, stop using it immediately, check and repair in time, troubleshoot, and replace the lubricant. When refueling, pay attention to the amount of oil to ensure that the reducer is properly lubricated.
