ABSTRACT:
An anti-backlash nut having one or more longitudinal flexural members with one end fixed and one end free-floating is disclosed which undergoes translational movement along a shaft. This anti-backlash nut is improved by providing ramps at the free-floating ends of the flexural members and means to apply axial forces on the ramps to thereby create radial force vectors which maintain the ramps in contact with the shaft even after the nut has become worn.
