Abstract
A rotational element coupling device in a supercharger includes a rotatable output shaft having tapered external splines and an output shaft axis of rotation. A coupling disk has a disk axis of rotation coaxial with the output shaft axis of rotation, a tapered internally splined bore coaxial with the disk axis of rotation to engage the tapered external splines, and a plurality of apertures defined in the coupling disk parallel to the disk axis of rotation. A plurality of pins each have a disk end and a timing gear end distal to the disk end. The plurality of pins matingly engages with the coupling disk at the disk end of the pins via the plurality of apertures. A timing gear is fixed to a supercharger rotor for rotation therewith. The timing gear has a plurality of apertures disposed therein to matingly engage with the timing gear end of the plurality of pins.
