ABSTRACT:
A leadscrew assembly includes a leadscrew having a leadscrew thread wire helically wound about a leadscrew axis in a plurality of cylindrical leadscrew-thread turns and having a leadscrew-thread pitch. A leadscrew wire nut assembly includes a nut-assembly wire helically wound about the leadscrew axis in a plurality of cylindrical nut-assembly turns and having a nut-assembly-thread pitch. The nut-assembly-thread pitch is substantially the same as the leadscrew-thread pitch, the nut-assembly turns overlie and mesh with the leadscrew-thread turns, and the nut-assembly wire has a permanent deformation therein. A wire-nut-assembly housing overlies and is bonded to at least some of the nut-assembly turns.
