The oil leakage of the reducer is a common problem. The cause of the oil leakage may be caused by the quality of the box, the quality of the lubricating oil, the quality of the oil seal, the air pressure inside and outside the box, and also if the lubricating oil is filled too much. overflow. In the event of oil leakage in the reducer, measures should be taken according to the actual situation. Below we will introduce a simple treatment method.
If the oil leakage is caused by the poor quality of the castings of the worm gear reducer, you can clean up the oil leakage of the castings with a detergent such as gasoline, and then inject 20% hydrochloric acid, take out the hydrochloric acid and clean it after a day, relying on chemical reaction to generate chlorine Ferrous iron blocks trachoma or crevices.
Oil leakage caused by poor oil return of the reducer. The oil returned by the reducer is not smooth. The oil splashed on the inner wall of the box cannot return to the oil pool as soon as possible, which may cause the oil to gradually leak along the shaft. The method I could not take is to install an oil seal on the head of the reducer, and at the same time use an oil sling ring to block the oil leakage and make it flow back to the oil pool. It is also possible to design an annular oil return groove on the parting surface of the machine base to allow the oil to flow back into the box and part of it to the bearing for lubrication. The gearbox cleaning and maintenance machine uses the original oil supply and discharge system of the gearbox and the filtered old oil to realize the functions of cleaning the gearbox, quickly filtering waste oil, and filling new oil. The operation process does not change the hardware facilities or The addition of cleaning agent ensures the safe operation of the gearbox and prolongs its service life. If this is one of the indispensable steps to reduce the use failure of the reducer, it is also ignored by many companies.
The internal pressure of the reducer is greater than the external atmospheric pressure is the main cause of oil leakage. The greater the pressure difference, the more serious the leakage. Therefore, reasonable pressure equalization measures can be taken. For example, if the vent cap and vent plug are designed on the tank cover, if the aperture of the vent cap and the vent plug is too small, it will increase the internal and external pressure difference and cause oil leakage. Therefore, the main check when selecting is to open the upper cover of the breather cap. After the reducer runs at high speed for a few minutes, touch the breather hole by hand.
