ABSTRACT:
An elastically conformable tapered pin-key for securing a part and a shaft where the part has a cylindrical bore for receiving the shaft and a keyway tangentially intersecting the bore, and the shaft has a tangential groove shallower than the depth of the intersection of keyway and the bore. The pin-key comprises two cylindrical surfaces converging at a small angle, and an axial cavity defining sidewalls sufficiently thin to allow the faces to elastically deform to conform to the keyway and groove. The pin-key is placed in the keyway and preloaded so that one face conforms to and engages the surface of the keyway and the second face conforms to and engages the surface of the groove in the shaft, thereby securing the part and the shaft against relative rotational or axial movement.
