Patent attributes
A cam hub mounting assembly for a camshaft having a cam cover rotationally mounted within a cam cover retainer with a bearing retainer ring therebetween having a plurality of slots, each slot rotationally maintaining a ball bearing positioned in a smooth U-shaped groove on the outside of the cam cover and in a smooth U-shaped groove on the inside of the cam cover retainer. The method of assembly allows the inner and outer grooves to collectively act as inner and outer bearing races for the ball bearings. The axial position of the cam cover is maintained within the bearing retainer and does not require endplay spacing when the cam cover is attached to the camshaft. The cam cover can have one or more balancing bores therein for rotationally balancing. The cam hub mounting assembly permits a camshaft to be attached thereto and to rotate at speeds exceeding approximately sixteen thousand revolutions per minute (16,000 rpm) for use in racing engines.
