ABSTRACT:
A slip clutch assembly has a push-pull rod on link and a motor driven threaded lead screw shaft which screws in and out of a threaded bore in the push-pull rod. A plastic generally cylindrical nut is interposed between the lead screw shaft and the bore in the push-pull member. The nut has spaced apart external rings which register in corresponding grooves in the bore in the push-pull rod. The nut has internal threads in which the lead screw turns. If the nut is prevented from moving axially by engaging the push-pull rod with a stop or load the rings on the nut slip on the grooves to prevent overload of the drive system and continued extension of the push-pull rod.
