GEARING OUTPUT SUPPORTED BY BALL BEARINGS

摘要

Aspects provide gear set systems that include cylindrical input gear having gear elements arrayed outwardly on a common input gear element radius from a central axis. A sprocket gear disposed about a sprocket pin has teeth disposed to mesh with the cylindrical input gear elements. An output disc body disposed about the cylindrical input gear and attached to the sprocket pin defines circular grooves on a radius from the central axis. Ball bearings are disposed between the output disc body circular grooves and respective grooves formed on a housing, wherein the ball bearings transfer an operational load of the output disc body conveyed through the output disc body circular grooves to the housing while rolling along the circular grooves during operation of the gear set system.

1. A system, comprising:
a cylindrical input gear comprising a plurality of round gear elements that are arrayed outwardly on a common input gear element radius from a central axis; a sprocket gear disposed about a sprocket pin and comprising a plurality of involute teeth that are disposed to mesh with the cylindrical input gear round gear elements, wherein the sprocket gear freely rotates about the sprocket pin; an inner output disc body disposed about the cylindrical input gear and attached to one end of the sprocket pin, the inner output disc body defining an inner output disc body circular groove on a first groove radius from the central axis within a plane normal to the central axis and facing inward; an outer output disc body disposed about the cylindrical input gear and attached to another remaining end of the sprocket pin, the outer output disc body defining an outer output disc body circular groove on a second groove radius from the central axis within a plane normal to the central axis and facing outward, the inner output disc body and the outer output disc body encompassing the sprocket gear and the cylindrical input gear; an outer housing encompassing the cylindrical input gear, the sprocket gear, the inner output disc body and the outer output disc body, the outer housing comprising a plurality of ring gear round gear elements that are each disposed on a ring gear radius from the central axis to mesh with the sprocket gear involute teeth, the outer housing defining an outward facing inner housing circular groove on the first groove radius from the central axis within a plane normal to the central axis and aligning with the inner output disc body circular groove, and the outer housing defining an inward facing outer housing circular groove on the second groove radius from the central axis within a plane normal to the central axis and aligning with the outer output disc body circular groove; a first plurality of ball bearings disposed between the outward facing inner housing circular groove and the inner output disc body circular groove, wherein the first plurality of ball bearings transfer an operational load of the inner output disc body conveyed through the inner output disc body circular groove to the housing via the outward facing inner housing circular groove while rolling along the outward facing inner housing circular groove and the inner output disc body circular groove during operation of the gear set; and a second plurality of ball bearings disposed between the inward facing inner housing circular groove and the outer output disc body circular groove; wherein the second plurality of ball bearings transfer an operational load of the outer output disc body conveyed through the outer output disc body circular groove to the housing via the inward facing inner housing circular groove while rolling along the inward facing inner housing circular groove and the outer output disc body circular groove during operation of the gear set.
