Attorney, Agent or FirmInternational ClassF16H 25/20 (20060101)AbstractAn anti-backlash nut is disclosed of the type which undergoes translational movement along a screw in response to relative rotational movement between the nut and screw. This anti-backlash nut has oppositely-directed longitudinal flexure members radially biased towards the screw to provide equal drag torque and minimum relative deflection for travel of the nut in either direction. | |
