ABSTRACT:
A rotor for use in speed sensing a transmission output shaft including circumferentially alternating teeth and voids which offers a variable reluctance flux path upon relative rotation thereof with respect to a fixed sensor. The rotor also includes an inward radially extending shoulder which is trapped between the yoke and a tapered roller bearing which also provides a surface over which the axial thrust required to trap the rotor may be distributed for application to a tapered roller bearing. Increasing the surface area of contact between the rotor and bearing minimizes premature bearing failures.
