ABSTRACT:
A speed reducing and torque transmitting mechanism includes a planar surface which is perpendicular to a first axis and a cone which rolls on the planar surface as the cone revolves around the first axis. The axis around which the cone rotates as it rolls intersects the first axis at the same point that the first axis intersects the planar surface so that under ordinary circumstances there is no slippage between the cone and the planar surface. The cone is driven by an input shaft which is coaxial with the first axis. An output shaft is connected to the cone via a crank having an arm oriented obliquely thereto in which arm the cone is rotatably journaled. An output shaft is connected to the cone adjacent to the apex thereof by a universal joint. The output shaft rotates in a direction opposite to the input shaft at substantially reduced rate with increased output torque. The mechanism is inherently torque limiting and delivers constant output torque if supplied with constant input torque.
