The paper suggests that pin gearing can be used for an antibacklash gear. 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. Pins on one side of a centerline are contacting the forward faces of a mating tooth gear. Simultaneously, pins on the other side of the centerline are contacting the backward faces of the gear. The correct center distance can be maintained in this multiple-contact mechanism by applying a force directed to each other center. A generating method of tooth-gear manufacture is also suggested. Contact and bending deformations as well as the gear stress are analyzed to help its design.read more

TL;DR: In this article, a gantry robot construction is described, which includes a pair of elongated substantially spaced parallel rails (112, 114), a bridge (120) spanning and substantially perpendicular to the rails, and a robot head (134) and support mounted on the bridge and movable relative to the bridge.
Patent
Antibacklash gears including rack and pinion gears
TL;DR: The meshing gear teeth consist of cylindrical profile teeth on a gear or rack and circular arc profile tooth on the other gear or pinion as discussed by the authors, which rotate with the motion of the meshing gears without loss of rolling contact from entrance to exit.
