ABSTRACT:
A differential gear system is disclosed for selectively transmitting power from one of two alternative power sources and which is particularly suited for use in actuating assemblies. The differential gear system includes an input gear rotatable about a sleeve assembly and in driving engagement with a spider gear assembly keyed to the sleeve assembly and driving an output gear also rotatable about the sleeve assembly. In one mode of operation, a first input gear system drives the differential input gear about the sleeve assembly while the sleeve assembly is held stationary by a second input gear system whereby power is transmitted through the spider gear assembly to the differential output gear. Alternatively, second input gear system drives the sleeve assembly while the first input gear system holds the differential input gear stationary whereby power is transmitted through the spider gear assembly to the differential output gear.
