Abstract: A helicopter rotor hub assembly for coupling a pair of helicopter blades to a helicopter mast. It includes a yoke assembly and a pitch assembly. The yoke assembly includes a central section and first and second sections extending respectively on opposite sides of the central section. Each one of the first and second sections has a pair of elongated arms defining inbetween a bearing-receiving interspace. The pitch assembly includes first and second attachment plates extending respectively along the first and second sections of the yoke assembly and first and second pitch bearing assemblies. Each attachment plate is connected to a respective one of the helicopter blades. Each pitch bearing assembly extends in the bearing-receiving interspace of a respective one of the first and second sections of the yoke assembly. Each pitch bearing assembly contacts a respective one of attachment plates to allow a pitch movement of the helicopter blades.
