The function of the excavator track adjuster assy is to ensure that the track has sufficient tensioning degree to reduce the vibration of the track during walking and the fall off during winding. The track is too slack, in addition to causing severe beating, increasing wear, but also easy to cause the phenomenon of new cutting; Track too tight, will aggravate the track pin and pin sleeve wear. Therefore, the track must have a suitable tension.
Hydraulic tensioning device is the most widely used. The tensioning device is filled with butter by hand pump, and the position of the guide wheel is adjusted by the cylinder and plunger to achieve the tensioning of the track.
The spring of the excavator track adjuster assy should have an appropriate cushioning stroke after pre-tightening, so that when the stone and other hard objects are clamped between the rail chain, the guide wheel, and the drive wheel, excessive tension is generated, forcing the guide wheel to move in the direction of the drive wheel, and compressing the spring, so that the track is relaxed and plays the role of a protective device. If the track is too tight to relax, you can unscrew the nozzle and release some butter from the cylinder.
