  • Propeller blade retention system with tapered roller bearing cartridge assemblies
    Patent number: 7845910
    Abstract: A propeller blade mounted with a preload adjacent a propeller blade root retention which increases the moment capacity of the retention for a given pitch diameter, yet permits pitching of the propeller blade about a blade axis in response to a propeller pitch change actuation system. The propeller blade retention assembly includes a tapered roller bearing set having a multiple of tapered roller bearing cartridge assemblies. Each tapered roller bearing cartridge assembly includes a retention cartridge and at least one tapered roller bearing element to facilitate installation and retention during assembly.

  • Offset crowned roller assembly for variable pitch propellers
    Patent number: 6514044
    Abstract: The expense of a bearing employed at the interface of a yoke (22) and a propeller blade pin (14) in a variable pitch propeller assembly is reduced in a bearing construction (16) wherein a bearing race (48) includes a crowned surface (50) adapted to engage a slot (20) in the yoke (22) and having a profile (Pi) wherein the diameter at one side (88, 90) of the race (48) is less than the diameter at the opposite side (90, 88) of the race (48).
