ABSTRACT:
An electromagnetically actuated spring clutch permits transference of rotational motion from an input hub to a coaxially-disposed rotatable shaft. A selectively actuable source of magnetic flux, such as an electromagnetic coil, is disposed around at least a portion of the shaft with a space therebetween. A housing, at least a portion of which is conductive of magnetic flux, substantially envelops the outer surface of the source. A shaft flange, also conductive of magnetic flux, is disposed around a portion of the shaft. A helical spring, having a first end attached to the input hub and a free end disposed adjacent the shaft flange, is loosely engageably coiled around the shaft, in the space between the shaft and the source. magnetic flux flowing through the shaft flange attracts the free end of the helical spring and thereby causes the helical spring to contact about and engage the shaft. A flange external to the housing diverts at least a portion of the magnetic flux away from an interface between the housing and the shaft flange.
