Tunnel mucking machine track maintains proper tension
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 directly subject to high compression stress. The pin and the pin sleeve are prematurely worn during operation, and the guide wheel is tensioned The elastic force of the spring also acts on the guide wheel shaft and the sleeve, which generates a large surface contact stress, which makes the guide wheel shaft sleeve easily ground into a semicircle, the track pitch is easily stretched, and the mechanical transmission rate is reduced, and the engine is wasted to drive Wheel and track power.
If the track of the tunnel mucking machine is too loose, the track is easily detached from the guide wheel and track roller, and the track loses the correct centering, causing the running track to fluctuate, beat, and impact, causing abnormal wear of the guide wheel and the supporting wheel.
Tunnel mucking machine track tension adjustment is by filling the tensioner cylinder with grease or putting out grease from the oiler, referring to the standard clearance of each model for adjustment. When the track pitch is stretched to the point that the group of track links needs to be removed, the toothing surface of the driving wheel and the pin sleeve will also be abnormally worn. At this time, appropriate treatment should be performed before the meshing condition deteriorates, such as pin and pin sleeve. Turn over, replace excessively worn pins and pin sleeves, replace track joint assembly, etc.
