ABSTRACT:
A shape memory metal actuator includes an actuator element that is secured at one end to an end fitting which is in turn secured to an overload protection spring. An adjustable screw is mounted to a frame and is positioned such that the overload protection spring biases the end fitting into contact with the adjustment screw. The end fitting lifts off of the adjustment screw when excessive stretching forces are applied to the actuator element. The adjustment screw can be moved to vary the rest position of the end fitting, thereby allowing manual compensation for cyclic creep of the actuator element.
