ABSTRACT:
An anti-backlash nut assembly is disclosed of the type which undergoes translational movement along a screw in response to relative rotational movement between the nut and screw. The assembly includes a nut which is axially-split into first and second portions, both of which have an internal thread complementary to the external thread of the screw. The two portions of the axially-split nut are retained in the radial direction by a spacer, and a spring is used to apply biasing in the longitudinal direction to minimize backlash.
