Description
In some tracked tractors, the tractor body rests on two trolleys, which have several support rollers. Bogies roll on rollers along a caterpillar chain. The roller body is a steel casting with a rim having a depression in the middle to guide the ridges of the links of the caterpillar chain. Hollow axle is pressed into inner hole of roller. Ends of axle protruding from roller are rotated in bronze bushings pressed into brackets. The brackets are attached to the trolley by two M14 bolts each. The design of the sealing device of friction surfaces is subject to special requirements, since during operation the support rollers are in a dusty and contaminated zone. The seal, which must reliably protect the rubbing surfaces from dirt, dust and water and prevent the leakage of lubricant, consists of two self-tightening glands and a labyrinth. Glands - combined, consisting of leather cuffs pressed by an annular spring and felt rings. The labyrinth is formed by a spring split ring that is constantly pressed against the inner surface of the protective cup. Thrust cups rigidly connected with roller by press fit and pins, and thrust washers with two projections enter cylindrical recesses in brackets. Adjusting washers are used to adjust axial clearance between cups and washers. The whole internal cavity of the axle, as well as the cavity of the thrust washer, is filled with lubricant. Oil is supplied with lubricant.
