ABSTRACT:
A linear weight actuator includes a clamp assembly adjustably connecting the power screw to the output spindle. The assembly includes an integrally formed key, riding in a slot formed in the actuator housing, which obviates the need for a separate key element. A mounting plate is adjustably clamped to the actuator housing, by a threaded mounting nut, such that the plate may be conveniently rotated relative to the housing. A linear bearing disposed in the mounting nut provides lateral support for the output spindle at a point spaced from the clamp assembly. A clamping ring encircles a thinned segment of the power nut and urges it against the power screw to prevent backlash.
