Free-wheel gear for use in machine tool, has drive element freely rotated in rotation direction, and brush- or skin-like lining provided with fibers, where drive element and drift element form brush free-wheel

摘要

The gear (1) has a drive element (2) and a drift element (3), where rotating motion to the drift element is transferred during rotation of the drive element in a rotation direction (D1). The drive element is freely rotated in another opposite rotation direction (D2), where the drive element and the drift element form a brush free-wheel (5). A brush- or skin-like lining (4) exhibits fibers (6) that are aligned in a tangential direction of the drive element and the drift element. Plastic bristles or metal wires are interconnected by a fabric.
