Publication number: 20240190560Abstract: 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.Type: ApplicationFiled: December 13, 2022Publication date: June 13, 2024Applicant: Textron Innovations Inc.Inventors: Charles Hubert Speller, Alan Wayne Falls, Nathan D.
