This paper draws attention to pin gearing for its antibacklash gear property. The gear tooth curve derived from a cycloidal curve furnishes the pin gearing with kinematic antibacklash, low pressure angle, and no interference among other features. The pins on one side of a centerline are contacting the forward faces of the mating tooth gear. Simultaneously the pins on the other side of the centerline are contacting the backward faces of the gear. The correct center distance can be maintained by applying a force directed to each other center for multiple contacts. A generating method of gear manufacture is also suggested. Contact and bending deformations as well as the gear stress are analyzed to help its engineering design.
