Abstract
A drive train system for rotating an axle in an external system about an axis which is perpendicular to a driven shaft. The driven shaft has a drive screw thereon and is rotatable about a fixed axis. A drive nut is located on the drive screw and is movable along the length thereof as the drive screw is rotated. A two-part, slidably interconnected crank arm has one part fixed to the axle and the other part slidably interconnected with the drive nut. A power drive is operably connected to the driven shaft through a friction drive including a driven member mounted on the shaft by means of a slip fit through a center hole and a friction plate rotating with the shaft through a center opening. An annular-ring surface between the driven member and the friction plate creates an interface which limits the frictional drive force developed thereby.
