Abstract: The present invention includes a rolling element bearing system and method of using the same, comprising: a ball bearing comprising an inner race coupled to an inner shaft (journal) at an outer surface of the inner shaft, an outer race coupled to an outer shaft at an inner surface of the outer shaft, and a roller element disposed between the inner race and the outer race, wherein the inner race and the outer surface of the inner shaft form a pocket between a portion of the inner race and the outer surface, and the inner race comprises an orifice through the inner race to fluidly connect the pocket and the rolling element.

Abstract: A hybrid composite reinforced ring gear minimizing radial deformation during high RPM conditions includes a composite backing secured to a metal rim. In use, at operating temperature the composite backing contracts while the metal rim expands thus creating a compressive stress on the metal rim and significantly reduces radial deformation due to centrifugal forces as compared to an all steel ring gear.
