Analysis And Test Of Oil Leakage Of Gear Reducer

- Dec 22, 2020-

In the case of the lubricated reducer running, the sealing condition of this gear reducer can be obtained by looking for oil leakage. The most important factor affecting the quality of gear reducer is determined by the gear set and gear material.

How to solve the oil leakage and heat generation of the worm reducer?

The oil leakage and heat generation of the worm reducer are caused by four reasons: the surface quality of the meshing friction surface, the quality and amount of lubricant added, the combination of materials, the assembly quality and the use environment.

Generally speaking, worm gear reducers use non-ferrous metal worm gears and harder steel worms to improve work efficiency. However, worm gears and worms are driven by sliding friction. In this process, it is inevitable that a large amount of heat is generated, and the higher temperature causes differences in the thermal expansion of various parts and seals in the worm reducer, resulting in gaps between the mating surfaces, and the oil becomes thinner due to the increase in temperature, which is likely to cause leakage.

We adopt a targeted solution strategy based on the main reason for this problem. The first is to use better material worm reducer parts, especially worm gears, worms, and oil seals. This is the main source of heat generation. These accessories are not compared. Good quality assurance, no matter how many methods are used to treat the symptoms but not the root cause, the root causes of oil leakage and fever cannot be solved.

Secondly, there is no need to say more about the quality and amount of lubricating oil. Good-quality lubricating oil is the driving force for the high efficiency of the worm reducer. Of course, it does not mean that the lubricating oil has to be filled up every time. Every worm reducer has an appropriate amount of lubricant to add, and it must not exceed that standard.

Finally, there is the problem of the use environment of the worm reducer. A good working environment is easier for the maintenance of the machine, but if the working environment is harsh, it is better to choose a reducer that can withstand use and wear.
