ABSTRACT:
Apparatus for converting rotary motion of a screw into linear motion includes three circumferentially spaced nut segments each resiliently mounted for displacing in a radial direction normal to the screw axis. A thin flat plate spring member provides a resiliency to the nut segments in a direction normal to the screw axes. The nut segments include a set of parallel triangular screw threads with the roots undercut and the crests removed for averaging out the contact between the nut segments and the screw to an area along the pitch diameter of the screw.
