Hydraulic oil, engine oil, gear oil and other oil products shall be replaced during maintenance of excavator. In daily maintenance, many people pay more attention to replacing hydraulic oil and lubricating oil. Every maintenance will also pay special attention, so more people will ignore the replacement of gear oil. During daily use, the gear oil may leak out without being noticed, and it is easy to damage the bearing and gear after lacking the gear oil. Serious will cause damage to the transmission. This article will summarize the causes of oil leakage of the traveling motor for reference only.
Since the traveling motor reducer is always exposed to the outside, it is easy to damage the floating oil seal in some harsh construction environments. This will cause oil leakage. Many excavators are used to demolish buildings or build new buildings. There are a lot of waste iron wires and steel bars on such construction sites. It is easy to get involved in the floating oil seal. After opening the floating throttle, it is easy to leak gear oil. Moreover, there are many sundries on the construction site. It is very likely that the iron wire is involved in the reducer or the oil leakage has not been found. Therefore, if it is found in time, replace the floating oil seal and replenish the gear oil. If there is a lack of gear oil, the gear oil in the reducer will be damaged between gears and between gears and bearings due to lack of lubrication.
