ABSTRACT:
A leadscrew assembly has a wire-wound leadscrew driven by a mechanical drive. A preloaded leadscrew wire nut assembly serving as a leadscrew follower includes a first wire nut having at least one turn of a first-nut wire overlying and engaged to the groove between the turns of the thread wire, and a second wire nut having at least one turn of a second-nut wire overlying and engaged to the groove between the turns of the thread wire. The second wire nut is spaced apart from the first wire nut along a leadscrew axis. The leadscrew wire nut assembly further includes a compressed preload spring maintaining a compression preload against the second wire nut, and a wire-nut-assembly housing overlying the first wire nut, the second wire nut, and the preload spring. The wire-nut-assembly housing maintains the preload spring in compression.
