ABSTRACT:
The power transfer of the present invention employs a driver having a medial section which includes a plurality of continuous, helical grooves and a plurality of axially aligned transfer material return flow paths. The medial section terminates at each end in a generally cylindrical head, each of which is provided with grooves which communicate with the medial section grooves. The head grooves conduct the power transfer material to the axial paths for axial flow through the driver. The power transfer material flows through the helical grooves, through the head openings, if so embodied or if used, through the head cooperating grooves and the axially aligned paths to travel a complete, circuitous route about and through the driver. A cooperating driven pinion of single or generally double enveloping worm gear configuration positions immediately adjacent the driver and is provided with a plurality of helical grooves of pitch, size and design to overlie the helical grooves of the driver to form closed paths through which the interposed transfer material travels as the driver is rotated. The multiple interposed transfer material contacts between the driver and the driven pinion results in an angular power transfer at greatly reduced friction and power requirements.
