Abstract:
A male shaft head adapted to be engaged into a female hub, and comprising:a first stage that adjoins a forward end of said shaft head and includes first de-centering means for introducing said shaft head into the hub and for providing radial play between said first stage of said shaft head and the hub, wherein a range of said radial play is eccentrically offset in a first radial direction relative to a central longitudinal axis of said shaft head, and first centering means for eliminating said radial play and for coaxially aligning the hub with said shaft head as said shaft head is inserted beyond said de-centering means into the hub; a second stage that adjoins and overlaps said first stage and includes second means for rotationally aligning said shaft head with the hub while said radial play is provided therebetween and for then rotationally engaging said shaft head with the hub for positive coupled rotation thereof; and a third stage that adjoins said second stage and includes third means for fully rotationally engaging said shaft head with the hub for torque transmission there-between.
