bulldozers are the main earth-moving construction machinery. Due to the harsh operating environment, the incidence of failures is also high. Once a failure occurs, it will be shut down for maintenance. This will not only affect the progress of the construction project, but also increase the operating cost of the bulldozer itself. The following is the response to the failure of the bulldozer gearbox Methods and how to prevent track wear and improve its service life!

Gearbox gear failure

Gear failure is also a common type of bulldozer failure, which is mainly caused by damage to the seal ring of a certain row of gearbox pistons. At the same time, damage to the end face of a certain row of planetary wheels may also cause the gearbox to fail to shift normally. Replace it with a new seal ring or end gasket, and after replacement, gear shifting can be completed normally.

Bulldozer track wear prevention

Since the bulldozer is mainly driven by the chain during operation, if the tension of the chain is not suitable during actual operation, it will directly affect the pressure and sliding conditions existing between the various components of the bulldozer during operation. If the wear condition is more serious, it is very likely that adverse events such as chain derailment will seriously affect the normal operation of the bulldozer. Therefore, in the prevention of crawler wear, the tension of the crawler during operation should be reduced as much as possible, and the pressure of each component in the walking mechanism should be reduced, so that the bulldozer crawler can operate normally.

And if the bulldozer has sharp friction and severe wear during operation, it should be taken seriously, especially after the chains and axles after being shy, due to the unevenness of the welding repair on the surface, it will cause the parts. The contact area is reduced, which in turn increases the strength of wear. If it is not handled in time, it may cause the welded layer of the link and the supporting wheel to fall off, which affects the welding effect and reduces the safe operating life of the bulldozer.

In this situation, the operator should prepare the bulldozer chain and check if necessary to add lubricating oil. This can effectively reduce the friction of the chain. At the same time, if the chain is running, if there is a loud noise, the construction should be stopped. , Do a thorough inspection, especially after welding, to ensure that the bulldozer crawler wear condition is reasonable, and reduce the incidence of bulldozer failure.
