How to avoid crawler type bulldozer gnaw track phenomenon

The walking mechanism of crawler bulldozer is mainly composed of idler, carrier roller ,track roller, sprocket, track link ,crawler tensing device, walking frame and so on. Its main function is to support the body mass, reduce the impact and vibration caused by uneven road surface on bulldozer, and transform the power output of engine into traction force.In the process of bulldozer's use, sometimes there will be abnormal wear of the guiding wheel, the supporting sprocket, the supporting wheel and the crawler, that is, the phenomenon of gnawing the track, which not only affects the working efficiency of bulldozer, but also reduces the service life of these parts.
The problem of track gnawing by crawler bulldozer is a difficult problem affecting product quality, which has not been solved thoroughly for a long time.To this end, we have been through many on-site tracking detection, analysis and research, and may cause the problem of "gnawing track" for investigation.We think that the reason of track gnawing of crawler bulldozer mainly lies in the out-of-tolerance of welding and machining of frame and assembly of "four rollers "(idler, carrier roller , track roller and sprocket).The following specific analysis, and proposed solutions.The frame is the core component of the walking device of crawler bulldozer, and the "four rollers" and the tightening buffer device are both.
When the crawler bulldozer turns in place on the muddy ground, the failure of dropping or gnawing the track often happens, which affects the normal use of the machinery, causes the early wear and tear of the parts of the walking system and shortens the life.Through force analysis and repair practice, we think that reasonable adjustment can solve this problem more smoothly.Produce drop rail, the main reason that gnaw rail is, walk system. The frame and the crawler walking device should be checked regularly to avoid the deformation of the frame caused by improper use and other reasons, and reduce the track gnawing and abnormal wear phenomenon of the crawler.
