Overhead Crane reducer leakage reason

Sep 01, 2017
First, the unreasonable design, such as the design of no ventilation hole or ventilation hole is too small, the overhead crane reducer internal pressure and external pressure can not be balanced, resulting in lubricating oil leakage; because the overhead crane operating mechanism reducer oil tank is composed of upper and lower oil boxes, after long running, the two boxes connection surface may does not seal well to leak oil.
Second, the Overhead Crane manufacturing and design can not meet the requirements, the oil box connection surface precision is not enough, resulting in oil leakage.
Third, the improper overhead crane operation and maintenance, will cause multiple clogging, resulting in too high internal pressure, too much oil, too high oil level; connecting bolts loose, lead to the combination of two boxes is not tight.
