Abstract:
1. A load carrying axial positioner with overload energy absorption, the positioner comprising: an outer tube having first and second ends; a threaded actuator rod extending axially between the first and second ends of the outer tube; a drive operable to rotate the actuator rod; a threaded member threadably mounted on the actuator rod and axially movable between the ends of the outer tube, the threaded member including a radial flange extending toward the outer tube; a radially extending load ring axially movable within the tube and spaced axially from the radial flange a radially expandable spring positioned axially between the radial flange and the load ring, the spring operative to radially expand when compressed between the flange and the load ring to exert radial force against the outer tube, thereby generating resistance to axial motion of the load ring within the tube; the load ring having a plurality of axially extending force transmitting elements extending through one end of the outer tube; and
