Reasons and Countermeasures for Oil Leakage of Bridge Crane Reducer

During the use of bridge cranes, there may be oil leakage from the reducer. A reducer with severe oil leakage not only loses a lot of lubricating oil, but also has a negative impact on the cleanliness and hygiene of the crane itself and the surrounding environment, and can also affect the progress of work. What is the cause of oil leakage in the reducer? How should we prevent and deal with the gearbox that has already leaked oil? Let's summarize briefly.

3 Reasons for Reducer Oil Leakage:

• Unreasonable design, such as the lack of ventilation holes or the ventilation holes being too small, which makes it impossible for the internal pressure and external pressure of the reducer to balance, resulting in the leakage of lubricating oil; Due to the fact that the oil tank of the reducer of the trolley traveling mechanism is composed of upper and lower boxes, the connection surface between the two boxes is not tightly sealed and prone to oil leakage due to long-term operation.

• The manufacturing design does not meet the requirements, and the accuracy of the box joint surface is insufficient, resulting in poor sealing and oil leakage.

• Improper use and maintenance can cause multiple blockages, resulting in high internal pressure, excessive oil volume, and high oil level; The connecting bolts are loose, causing the joint surface between the two boxes to be loose.

Countermeasures:

• In order to prevent oil leakage in the reducer, the design should be improved by adding ventilation devices on the observation hole cover and refueling hole cover of the reducer to ensure balanced pressure inside and outside the box and smooth airflow;

• Improve the machining accuracy of the joint surface and each mating surface of the two boxes to prevent box deformation;

• In addition, it is necessary to do a good job of maintenance, regularly check and clear the vent holes of the reducer, maintain the appropriate amount of oil, inspect and repair the split surface of the box body, and replace it if it is severely deformed; Clean the oil return groove and tighten the bolts.
