    摘要: A bearing system includes an inboard bearing assembly (120) and an outboard bearing assembly (114). The inboard bearing assembly (120) includes an inboard fitting (122) and an inboard race (124). The inboard fitting includes a plate (126) with a convex mating surface (142) and a first aperture (128) formed through the plate for receiving a blade root (112) of a rotor blade (108). The inboard race comprises a concave mating surface (144) configured to receive the convex mating surface (142), a second aperture (125) formed in the inboard race (124). The outboard bearing assembly includes an outboard bearing assembly (114) comprising an outboard fitting (118) having an aperture formed therethrough for receiving the blade root (112) of the rotor blade (108).
