If the tension is excessive, the spring tension of the guide wheel acts on the track pin and pin sleeve, the outer circle of the pin and the inner circle of the pin sleeve are always subjected to high extrusion stress, and the pin and pin sleeve are abraded prematurely during operation. At the same time, the spring tension of the guide wheel acts on the guide axle and sleeve, resulting in large surface contact stress, which causes the guide wheel The axle sleeve is easy to be grinded into a half circle, the track pitch is easy to be elongated, and the mechanical transmission efficiency is reduced, which wastes the power transmitted by the engine to the driving wheel and the track
Construction machinery giants are looking forward to the next year in the market surge, head-high group of heroes to become the leader. Looking back on the past year, each of them showed their magic power in order to seize the construction machinery market. Financing lease, mortgage payment and other sales methods emerge in endlessly, which can be described as the dark end of the day. However, after several years of development, the market of loaders and excavators is close to saturation, and it is difficult to emerge the blowout trend at the beginning of the year. It is believed that next year's construction machinery market will not be as smooth as people speculate. The current European debt crisis has seriously affected European import and export markets. When the "dark clouds" of European debt come to the fore, it is likely to make the future market more depressed. Where should we focus the market right now?
Check and adjust the front wheel of the front wheel positioning tractor with too large camber and very small front harness, which is easy to cause eccentric wear during walking. The main reason is that the front axle bearing and sleeve are deformed by impact, or the front axle telescopic sleeve fastener is loosened, which will change the front wheel alignment angle and cause abnormal wear and tear. Therefore, in the process of using, it is necessary to check whether the positioning angle of the front wheel is appropriate, and adjust the front harness.
