ABSTRACT:
A bearing assembly monitors angular velocity about its axis of rotation. The bearing assembly includes an outer race having a pair of tapered raceways presented inwardly, and two inner races in the form of cones, each having a tapered raceway presented outwardly toward one of the raceways of the outer race. The raceway of each cone lies between a thrust rib and end rib at the ends of the cone and tapers downwardly toward the end rib, all such that an undercut exists at the small end of the raceway where the end rib projects beyond it. The bearing assembly also has tapered rollers organized into two rows which are located between the opposed raceways of the outer race and the two cones. The cones abut at their end ribs, and the end ribs of the two cones carry a target wheel in the space between the two rows of rollers. The target wheel which is monitored by a sensor set into the outer race between its two raceways, has clips which project into the undercuts of the two cones to thereby interlock the target wheel and cones. The rotating target wheel rotates with the cones and causes the sensor to produce an electric signal, the frequency of which reflects the angular velocity of the cones or whatever may be attached to the cones.
