Gear for driving rotating drums of milling vehicles, compounding drums etc.

摘要

The gear has a toothed drive wheel in the form of a roller ring. The part-circle sections of the cogging (2a) of the driven discs (2,3,4) are positioned on a segment of a truncated cone shaped outer surface of a pitch cone. The drive discs, at least near the drive shaft (10) perform a circular translation with the aid of a cam (8). The drive discs, near a second bearing, describe a movement along a straight or curved guide or describe an oscillating motion with the aid of a coupling, or a circular translation with the aid of a second cam (7). The drive discs operating on parallel planes fit into the drive wheel (16), near the centering angle of the drive wheel.
