Abstract
A belt drive configured to cooperate with a drive mechanism is disclosed. The belt drive includes a drive belt pulley reciprocally coupled to the drive mechanism such that the drive mechanism reciprocally translates between a power stroke and a return stroke, a driven pulley reciprocally coupled to the drive belt pulley via a drive belt such that the drive belt include a plurality of asymmetrical drive teeth configured to cooperate with a plurality of asymmetrical driven teeth disposed on the driven pulley, and an engagement mechanism disposed substantially adjacent to the drive belt and the driven pulley such that the engagement mechanism is configured to cooperate with the drive belt during the power stroke, and the drive belt substantially disengages the driven pulley during the return stroke.
Claims20
A belt drive configured to cooperate with a drive mechanism, the belt drive comprising:
- a drive belt pulley coupled to the drive mechanism,
- wherein the drive mechanism translates between a power stroke and a return stroke;
- a driven pulley coupled to the drive belt pulley via a drive belt, wherein the drive belt include a plurality of asymmetrical drive teeth configured to cooperate with a plurality of asymmetrical driven teeth disposed on the driven pulley;
- and
- an engagement mechanism disposed substantially adjacent to the drive belt and the driven pulley,
- wherein the engagement mechanism is configured to cooperate with the drive belt to initiate the power stroke, and
- wherein the drive belt substantially disengages the driven pulley during the return stroke.
A belt drive system comprising:
- a reciprocating drive mechanism including a drive belt pulley configured to provide a power stroke and a return stroke,
- wherein the drive belt pulley includes a plurality asymmetric spoke teeth disposed about a circumference of the drive belt pulley;
- a driven pulley disposed away from the drive belt pulley,
- wherein the driven pulley includes a plurality of asymmetrical driven teeth disposed thereon, and
- wherein each of the plurality of asymmetrical driven teeth includes a driven surface;
- a drive belt configured to releasably couple the drive belt pulley to the driven pulley as the drive mechanism transitions between the power stroke and the return stroke,
- wherein the drive belt includes a plurality of asymmetrical drive teeth disposed thereon, and
- wherein each of the plurality of asymmetrical drive teeth includes a drive surface;
- and
- an engagement mechanism disposed substantially adjacent to the drive belt and the driven pulley,
- wherein the engagement mechanism is configured to cooperate with the drive belt to initiate the power stroke, and
- wherein the drive belt substantially disengages the driven pulley during the return stroke.
A belt drive system:
- a drive belt pulley reciprocally coupled to a drive mechanism configured to translate between a power stroke and a return stroke;
- a drive belt fixedly coupled to the drive belt pulley, the drive belt including a plurality of asymmetrical drive teeth and wherein each of the plurality of asymmetrical drive teeth includes a drive surface arranged substantially perpendicular to a belt surface;
- and
- a driven pulley releasably coupled to the drive belt pulley via the drive belt, wherein the driven pulley includes a plurality of asymmetrical driven teeth and wherein each of the plurality of asymmetrical driven teeth includes a driven surface arranged to cooperate with the drive surface;
- wherein the drive belt cooperatively engages the driven pulley throughout the power stroke, and wherein the drive belt disengages from the driven pulley throughout the return stroke.
