Abstract:
1. A high speed rolling element bearing system for reacting a primary thrust load, comprising: a first high speed rolling element thrust bearing; a second high speed rolling element thrust bearing, wherein the first high speed rolling element thrust bearing and the second high speed rolling element thrust bearing are dimensionally configured to react the primary thrust load in parallel; a clutch operable for selectively coupling first and second rotatable spools together, the clutch adapted to transmit the primary thrust load during a clutching operation and remove the primary thrust load upon completion of the clutching operation; a preload generator operative to generate a thrust preload between the first high speed rolling element thrust bearing and the second high speed rolling element thrust bearing upon removal of the primary thrust load; and wherein the preload generator includes a split spacer with a pair of substantially U-shaped cavities opposing one another and a spring engaged within the opposing cavities.
