ABSTRACT:
An internally and externally threaded double nut is screwed onto the threaded shaft of a stepper motor. The nut is restrained from rotational motion thereby limiting it to translation along the shaft axis. An internally threaded output sleeve is screwed onto the external thread of the double threaded nut. The pitch of the nut internal thread is smaller than that of the external thread so that rotary motion reduction occurs at the output sleeve. A ball bearing is positioned in contacting support between the sleeve and the shaft thereby minimizing output sleeve tolerance accumulations of eccentricity and axial positioning.
