  • Performance sensor ring with reduced mass
    Patent number: 6498475
    Abstract: A sensor ring and method for forming same is provided in which the ring has a stamped configuration bent into a final configuration. The stamped configuration has a flat, annular sensor portion extending from a cylindrical hub portion and the sensor portion has a plurality of substantially identical, circumferentially spaced window openings therein. Each window opening has an inner edge adjacent to and spaced radially outward from the hub and an outer edge spaced radially inward from the outer peripheral end of the sensor portion and leading and trailing edges extending, respectively, from the ends of the inner and outer edges to form each window as a polygon, preferably a trapezoid. In the final configuration, the sensor portion has a bight segment extending radially outward from the hub and a sensor or finger segment extending from the bight segment in the direction fo the hub to form a U-shaped cross-section.
