ABSTRACT:
A motorized drive is provided, of a type which includes a pair of coaxial shafts that are individually motor driven, which is especially economical to manufacture and assemble, while providing reliable operation. The drive includes coaxial shafts and upper and lower assemblies that each includes a motor mounted on a plate disposed about the shaft, a gear disposed about the shaft and driven by the motor, and a tapered bushing which couples the gear to a corresponding shaft. A coil spring disposed around the shafts presses the upper and lower assemblies apart to urge the tapered bushings into the tapered holes of the gears to couple them.
