Filed:

Dec 29, 2009

Appl. No.:

12/648767

Inventors:

Don R. Cavalier - Walker MI, US
Aaron M. Klap - Grand Rapids MI, US

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

B64C 3/38
B64C 5/10
B64C 9/00
B64C 13/00

US Classification:

244 992, 244213, 244215

Abstract:

A flap actuator is provided for controlling movement of a flap on a wing of an aircraft. The flap actuator includes a housing having a leading end and a trailing end. A ball nut is rotatably supported in the housing. A motor has a rotatable drive shaft that is rotatable in first and second opposite directions. A gear assembly translates rotation of the drive shaft to the ball nut. A ball screw extends along a longitudinal axis and has a terminal end operatively connectable to the flap. The ball screw is movable between a first retracted in response to rotation of the ball nut in a first direction and a second extended position in response to rotation of the ball nut in a second direction. A one-way roller clutch is operatively connectable to the ball nut. The roller clutch engages the housing and prevents rotation of the ball nut in a first direction in response to a compressive force on the ball screw by the flap. First and second concentric gimbals are positioned about the longitudinal axis adjacent the housing.

US Classification:

244 992, 244215, 244216

Abstract:

A roller clutch assembly for use in an actuator is provided that includes a roller cage and at least one roller. A lubricating medium at least partially surrounds the roller cage and the roller. The roller cage includes at least one wiper configured to move the lubricating medium toward its functional location adjacent the rollers. An aircraft actuator for controlling movement of an aircraft flight control surface is also provided that includes a ball nut and a ball screw operatively connected to the flight control surface. A one-way roller clutch is operatively connected to the ball nut and substantially prevents rotation of the ball nut in a first direction in response to a compressive force on the ball screw. A roller clutch assembly according to the present invention is positioned between the ball nut and the one-way roller clutch.

Abstract:

A flap actuator is provided for controlling movement of a flap on a wing of an aircraft. The flap actuator includes a housing having a leading end and a trailing end. A ball nut is rotatably supported in the housing. A motor has a rotatable drive shaft that is rotatable in first and second opposite directions. A gear assembly translates rotation of the drive shaft to the ball nut. A ball screw extends along a longitudinal axis and has a terminal end operatively connectable to the flap. The ball screw is movable between a first retracted in response to rotation of the ball nut in a first direction and a second extended position in response to rotation of the ball nut in a second direction. A one-way roller clutch is operatively connectable to the ball nut. The roller clutch engages the housing and prevents rotation of the ball nut in a first direction in response to a compressive force on the ball screw by the flap. First and second concentric gimbals are positioned about the longitudinal axis adjacent the housing. The gimbals interconnect the housing to the wing.

International Classification:

F16H 25/24
B64C 13/28
F16H 25/22

Abstract:

An actuator includes a drive assembly, a ball screw, and a ball nut. The ball nut may include a first nut member, a second nut member; and an arm extending from the first nut member. The arm may include a first portion and a second portion. The first portion may extend radially outward from the first nut member. The second portion may extend substantially axially from the first portion such that at least some of the second portion is disposed radially outward of the second nut member.
