Abstract:
1. Apparatus for interconnecting a high speed driver with a speed reducer, the apparatus comprising: an elongated gear shaft defining a longitudinal axis and having opposed first and second ends; means for operatively connecting the first end of the gear shaft to the speed reducer; a gear coupling positioned at the second end of the gear shaft adjacent to the driver, the gear coupling being axi-symmetric and including radially inwardly facing and radially outwardly facing sets of splines, the sets being intermeshed and providing a gear ratio of 1:1, the gear coupling further including a retainer ring for preventing axial run-out of the gear shaft, and means for connecting to the driver; and a system for lubricating the intermeshed inwardly and outwardly facing splines with oil during rotary motion, the system flowing oil axially past the intermeshed splines, wherein the retainer ring is positioned axially to abut the outwardly facing splines, and wherein the retainer ring is sized and configured to define with the roots of the inwardly facing splines, openings for regulating lubricating oil flow axially past the intermeshed inwardly and outwardly facing splines.
