Reasons and measures for oil leakage of gantry crane reducer

 There are three common reasons for oil leakage of gantry crane reducer:

       1. Due to the unreasonable design of the Crane factory: In the design process, lack of design such as no vent or too small vent will cause the internal and external pressure of the reducer to be imbalanced and leak failures, resulting in leakage of the reducer's lubricant. It is also possible that the connection surface of the reducer is not tightly sealed during long-term use, which may cause leakage.

       2. The limited technological level results in insufficient precision such as the contact surface of the box body, which causes poor sealing performance and oil leakage.

       3. Due to improper maintenance by the gantry crane operator or maintenance personnel in the daily use process, the inner side is blocked in many places and the inner pressure is higher than the external pressure. At the same time, too much oil and the fasteners are not tightened, etc., will cause two tanks. The joint surface between the bodies is not tight, causing oil leakage.

       In order to avoid oil leakage in the reducer, the manufacturer should enhance the process level and optimize the design plan: a ventilation device can be added to the oil filler hole cover to ensure the internal and external pressure is balanced and smooth. At the same time, the process precision between the joint surfaces of the two boxes should be enhanced in the design process, so as to avoid the occurrence of oil leakage failures due to loose contact surfaces. At the same time, in the daily use process, the gantry crane reducer must be maintained and maintained, and the ventilation holes, oil volume, box body, fasteners, etc. must be regularly checked whether they are in a regular state.
