Abstract
An 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.
Claims8
An anti-backlash nut designed to undergo translational movement along a screw having an external thread thereon in response to relative rotational movement between the anti-backlash nut and screw, said nut having a hollow cylindrical bore with an internal thread complementary to the external thread on the screw and said nut comprising, in combination:
- a. a continuous portion extending longitudinally from one end of said nut to the other and thereof;
- b. oppositely-directed longitudinal flexure members, said flexure members having one end fixed to said anti-backlash nut and their other end free-floating;
- and,
- c. means for biasing said oppositely-directed longitudinal flexure members towards the external thread of said screw.
