ABSTRACT:
The present invention provides a radial drive connection between a movable flange and the shaft of an adjustable pulley. Specifically the movable flange is driven through the use of supports fixed to the shaft which radially fix the movable flange while allowing for axial movement. The supports are provided through a rigid disc splined to the shaft. The disc has an annular extension extending therefrom. Attached at one end to the disc and at the opposite end to the extension is at least one guide. Each guide includes a bolt or pin and an annular sleeve. The movable flange is configured to have a foot which has an annular wall to it. Through this wall the movable flange slidably engages the guide and provides a radial drive connection. Because the wall and guide slide, however, the movable flange is permitted to move in the axial direction.
