Recently, we received feedback from customers that due to the untimely maintenance of the machine, the reducer of the overhead crane had oil leakage. After receiving this feedback, we immediately kept in touch with the customer and inquired about the purchase time, type of bridge crane and usage frequency of the customer. After consulting the relevant engineers, we provided the customer with a series of after-sales services, and the customer was very satisfied with our service.

Overhead cranes are widely used in modern industry and play an irreplaceable role in the healthy development of enterprises. However, while overhead cranes bring high efficiency, convenience and speed in the production process of enterprises, due to the unsafe factors of machinery, frequent accidents will bring huge economic losses to enterprises. How to ensure the safe operation of overhead cranes is our top priority.

During the use of bridge cranes, the problem of oil leakage from the reducer is relatively common. The reducer with serious oil leakage will not only lose a lot of lubricating oil, but also have a bad impact on the cleaning and hygiene of the crane itself and the surrounding environment, and also affect the progress of the work. What is the reason for the oil leakage of the reducer? How should we prevent and how to deal with the reducer that has leaked oil to briefly summarize.

There are three main reasons for oil leakage of the reducer: First, due to unreasonable design, such as no ventilation holes or too small ventilation holes, the internal pressure of the reducer cannot be balanced with the external pressure, resulting in the leakage of lubricating oil; due to the deceleration of the trolley operating mechanism The oil pool of the device is composed of upper and lower boxes. Because of long-term operation, the connection surface of the two boxes is not tightly sealed and easy to leak oil. The second is that the manufacturing design fails to meet the requirements, and the accuracy of the joint surface of the box is not enough, which leads to the lack of tight sealing and oil leakage. Third, improper use and maintenance caused multiple blockages, resulting in too high internal pressure, too much oil, and too high oil level; loose connecting bolts made the joint surface of the two boxes not tight.

In order to prevent oil leakage of the reducer, the design should be improved, and a ventilation device should be installed on the observation hole cover and the oil filling hole cover of the reducer to ensure that the pressure inside and outside the box is balanced and air flow smoothly; Prevent the deformation of the box; in addition, do maintenance work, check and unclog the vent holes of the reducer frequently, the oil amount is appropriate, overhaul and repair the split surface of the box, and replace it if the deformation is serious; clean the oil return tank and fasten the bolts.
