A variable speed drive mechanism includes a fixed disk concentric with, attached to, and rotatable with a shaft about a central axis. A plurality of pulley segments are supported by the fixed disk, and are moveable relative to the fixed disk in a radial direction relative to the central axis. A moveable disk is concentric with the shaft, and is rotatably moveable about the shaft relative to the fixed disk. The moveable disk defines a spiral groove having a center concentric with the shaft. The pulley segments include a guided groove portion engaged with and moveable along the spiral groove. Rotation of the moveable disk relative to the fixed disk rotates the spiral groove about the central axis relative to the pulley segments, thereby moving the guided groove portions along the spiral groove to move the pulley segments radially relative to the central axis.
