Once the oil leakage occurs in the gear reduction motor, it will not only lead to serious loss of lubricating oil, but also the equipment may be seriously short of oil without your knowledge, causing the equipment to be scrapped in advance. What are the reasons for the oil leakage? If you want to Yes, then follow our steps to get to know:

1. Too much fuel

During the continuous operation of the gear reduction motor, the oil pool will be stirred, and the lubricating oil is easy to splash. Once there is too much lubricating oil in the house, the oil will gather in the shaft seal, and oil leakage will naturally occur.

2. The pressure difference between the inside and outside of the geared motor is too large

When the equipment is running, it will be heated by the ambient temperature and the friction of the moving pair, which will cause the temperature of the entire gear reduction motor to rise. If the vent hole is blocked at this time, the internal temperature will rise and it will be in contact with the external environment. The pressure difference becomes larger, and the lubricating oil leaks out under the influence of such factors.

3. Unreasonable structural design

The hole cover plate of the gear reduction motor is too thin, and the hole cover plate is prone to deformation after being fixed with bolts, so that the lubricating oil will flow out from the uneven joint surface. During production, some parts have not been annealed or aged, and the internal stress has not been eliminated, which will also cause deformation of the hole cover and cause oil leakage.

4. Improper maintenance process

When checking and repairing the geared motor, if the dirt and sundries on the joint surface are not cleaned up, the sealant inside is not selected correctly, the direction of seal installation is wrong or the seal is aging, etc., can cause oil leakage.

What kind of oil should be added to the motor reducer?

Refueling the motor reducer is a very normal job. The machine will be slow during use. At this time, it is necessary to add suitable oil to the machine’s rollers. Once the oil is not correct, it will cause the machine to heat up, and even the machine will be scrapped. Serious problem, know that different types of reducers need to add different lubricating oil.

Generally speaking, lithium-based grease is added to small reducers; worm oil is added to worm gear reducers; for vertical reducers, oil is usually added from the upper end, and if a large reducer needs to add an oil pump to ensure that the machine can Full contact lubricant.

When adding lubricating oil, how to add oil and how much? It is also a question asked by many people. Usually, the reducer will have a refueling port, and the refueling position line will be marked on the refueling position. In order to facilitate the addition of lubricating oil, you must Pay attention to unscrew the vent hole. In addition, as for where to refuel, it is usually enough to fill up the oil cup or the oil window.

However, the frequency of refueling should not be too frequent. It depends on the operation of the machine. In addition, after the machine has been running for a while, pay attention to whether the oil is dirty. If there are impurities, it is recommended to replace the new oil. Machine life is beneficial.
