  • Torque Transmission Apparatus and a Collar
    Publication number: 20200247236
    Abstract: A torque transmission apparatus having a shift collar and a drive component. The shift collar may have a collar gear that may have a collar tooth that may have a concave collar tooth side surface that may be centered about a transverse collar tooth plane. The drive component may have a tooth that may have a convex lateral side surface centered about a transverse tooth plane. The concave collar tooth side surface may cooperate with the convex lateral side surface to align the transverse collar tooth plane with the transverse tooth plane.
