Abstract:
1. A system to transmit rotational energy, comprised of: (a) a single inner round axle shaft, and (b) two hollow outer round axle shafts with approximately the same inside diameter, the inside diameter of said hollow round axle shafts will be slightly greater than the outside diameter of said single round axle shaft, the lengths of said hollow outer round axle shafts will be approximately equal and half the length of said single round axle shaft, and wherein only one end of each outer axle shaft is open, (c) said hollow outer axle shafts completely cover and enclose the inner axle shaft such that the faces of the outer axle shafts with the open ends abut one another when fully enclosing the inner axle and the ends of the inner shaft are flush to the inner side of the closed end of the outer shafts, (d) lubricant placed within the shaft assembly is restricted from leaving the enclosed axle shaft assembly and debris is prevented from entering the enclosed axle shaft assembly, (e) two fixed bearings are placed over the outer shafts of the axle shaft assembly such that each end of the inner axle shaft within the outer shaft contacts an inner face of the outer shaft in the same plane as an outside face of the bearing contacts the end of the outer shaft wherein this positioning restricts the movement of the outer axle shafts away from a parallel center to center alignment with said inner axle shaft and evenly spreads any force of such potential misalignment along the entire length of the inner axle shaft and limits any end to end movement of the entire enclosed axle shaft assembly, wherein said fixed bearings each have, (f) drive gear hubs on an inside face of the bearings help restrict the assembly's movement, thus maintaining the relative positions of all axles and bearings.
