  • Axially biased nonintegral raceways for rotorcraft masts
    Patent number: 12208886
    Abstract: A propulsion assembly for a rotorcraft. The propulsion assembly includes a mast having an internal ledge, a raceway station and an external ridge with at least a portion of the raceway station positioned axially between the internal ledge and the external ridge. A nonintegral raceway is receivable by the raceway station to form a press fit joint between the mast and the nonintegral raceway. A mast bearing assembly includes a plurality of bearings configured to engage an outer surface of the nonintegral raceway. The internal ledge is configured to generate a nonuniform normal force between the mast and the nonintegral raceway along the raceway station that axially biases the nonintegral raceway toward the external ridge, thereby securing the nonintegral raceway at the raceway station.
