Helical gear reducer troubleshooting method

The helical gear reducer is a novel reduction transmission device.Adopting the advanced design concept of optimization and modular combination system, it has the characteristics of small size, light weight, large transmission torque, stable starting, and fine transmission ratio classification.So what should I do if the helical gear reducer fails?The following editor summarizes a few troubleshooting methods for you:


Guarantee assembly quality

Some special tools can be purchased or made by yourself. When disassembling and installing the reducer parts, try to avoid knocking with other tools such as hammers; when replacing gears, worm gears and worms, try to use original accessories and replace them in pairs; when assembling the output shaft, pay attention to Tolerance fit; use anti-sticking agent or red dan oil to protect the hollow shaft to prevent wear and rust or scale on the mating area, which is difficult to disassemble during maintenance.

Lubricant selection

Helical gear-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 is stopped. , 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 and elastic and effectively reduce lubricating oil leakage.

Installation location selection

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

Lubrication maintenance

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 ℃ or the oil temperature exceeds 80 ℃, the quality of the oil decreases or the oil If there is too much copper powder and abnormal noise, stop using it immediately, check and repair it in time, remove the fault, and replace the lubricating oil.When refueling, pay attention to the amount of oil to ensure that the reducer is properly lubricated.
