ABSTRACT:
A mechanism for conversion between rotary and linear motion includes a rotatable roller carriage having a channel through which a shaft is passed axially. Shaft engaging drive rollers that are orbitally movable about the channel with the rotation of the roller carriage are positioned along the channel forming an acute angle therewith. Retaining rollers are held by the roller carriage parallel to the drive rollers to retain the drive rollers in a shaft engaging position. The drive rollers are driven by the retaining rollers in a rotary fashion to linearly advance the shaft.
