If the workers meet a problems covering the speed reducer leakage of bridge crane ,it not only affects the normal operation of the equipment, but also is the key to the safe operation of the bridge crane.There is a detailed introduction of speed reducer leakage problems for everyone by professional crane manufacturers .
First, its design is unreasonable. If it don’t has the air hole or just has a smal air hole, the internal pressure of reducer can not be balanced with external pressure,which result in the oil leakage. Because the tank is composed of the upper and lower boxes ,the sealing surface of the two boxes are not tight and easy to leak due to the long running time.
Second, the manufacturing design can not meet the requirements.The sealing surface of box is not enough, which causes the sealing being lost and the oil seepage.
Third, improper maintenance causes many blockages,which result in excessive internal pressure, excessive oil volume and excessive oil level.And the connection bolts are loose and the combination of the two boxes is not strict.
