 How to solve the oil leakage of the reducer

After using the reducer for a long time, a comprehensive inspection should be carried out so that we can find some hidden dangers in time. In order to make the equipment run efficiently, we generally refuel in time. But we should also solve the oil spill in time.

   1. Carry out the maintenance process carefully. When overhauling, you must carefully implement the process regulations. The oil seal must not be installed reversely, the outer edge must not be deformed, the spring must not fall off, the joint surface must be cleaned, the sealant must be evenly applied, and the amount of oil must not exceed the scale of the oil scale.

   2. Improve the vent cap and inspection hole cover. The internal pressure of the reducer is greater than the outside atmospheric pressure is one of the main reasons for oil leakage. If the pressure inside and outside the machine is balanced, the oil leakage can be prevented. The inspection hole cover must be opened every time the oil is added. Once opened, the possibility of oil leakage will increase once, and leakage will occur in the original place. For this reason, an oil cup type vent cap was made, and the original thin inspection hole cover was changed to 6mm thick, and the oil cup type vent cap was welded to the cover. The diameter of the vent is 6mm, which is convenient for ventilation. The pressure is equalized, and the oil is added from the oil cup when refueling, without opening and checking the hole cover of the reducer, reducing the chance of oil leakage.

   Three, wipe. The static sealing points can generally be leak-proof through treatment. However, due to the aging of the seals, poor quality, improper assembly, and high shaft surface roughness, the dynamic sealing points still have small leakages. The working environment is poor, and coal dust sticks to the shaft, making it appear oily. Therefore, it is necessary to wipe off the oil on the shaft after the equipment stops running.

   Fourth, maintain a smooth flow. To prevent the excess lubricating oil thrown on the bearing by the reducer gear from accumulating at the shaft seal, the excess lubricating oil needs to flow back to the oil pool in a certain direction. An oil return groove inclined toward the inside of the machine is opened in the center of the lower shell of the bearing seat, and a gap is also opened at the straight opening of the end cover.

   5. New sealing materials are used. For static sealing point leakage, a new type of polymer repair material can be used for sticky plugging, so as to achieve the purpose of eliminating oil leakage.

   Six. Improve the shaft seal structure.

  The oil leakage of the reducer is mainly related to some accessories. Especially check the fuel tank at this time. Note that the oil does not need to be very full, otherwise the possibility of oil leakage may increase. The other is to check the tightness of the equipment.
