  • Tooling and method for fabricating helical sector gear and related helical sector gear
    Patent number: 11867273
    Abstract: A helical sector gear having a body and a gear segment having a plurality of helical teeth. The gear segment has a toothed sector, on which all of the helical teeth are formed, and spacing segments on the opposite circumferential ends of the toothed sector. Each of the spacing segments has a circumferential surface, which is longer than a pitch of the helical teeth, and a radial surface that is formed in a helical manner that conforms to the helix angle of helical teeth. A die set for forming the helical sector gear and a related method are also provided.
    Type: Grant
    Filed: September 8, 2022
    Date of Patent: January 9, 2024
    Assignee: American Axle & Manufacturing, Inc.
    Inventors: Daniel R. Bankovic, Douglas Hanes, Martin J. Fannin
