Common fault maintenance of Bridge Crane

Due to the influence of vibration, wear, pressure, temperature and other factors, the static sealing parts of the joint surface often leak oil. The traditional treatment method is to dismantle the reducer, replace the sealing gasket or apply sealant, but it is time-consuming and difficult to ensure the sealing effect, and leakage will occur again in operation.

The driving wheel and the reducer of the bridge crane operate frequently, and the repeated reverse emergency stop and stop will increase the torque and vibration of each shaft of the reducer, which is easy to cause leakage. After the occurrence of such problems, the traditional methods are mainly repair welding or machining after brush plating, but both of them have some disadvantages: the thermal stress generated by repair welding at high temperature can not be completely eliminated, and it is easy to bend or fracture; while the brush plating is limited by the coating thickness, and it is easy to peel off, and the above two methods are metal repair, which can not change the "hard to hard" coordination relationship Under the combined action, it will still cause re wear.
