  • Patent number: 8596154
    Abstract: A ballscrew assembly for an actuator is provided. In an embodiment, the ballscrew assembly includes a ball nut assembly including a view port; a ballscrew provided within at least a portion of the ball nut assembly; an inner rod provided within the ballscrew in the direction of the longitudinal axis, the inner rod including an enlarged end portion; and a compression mechanism, such that at least a portion of the compression mechanism is provided between the enlarged end portion and the ballscrew. In another embodiment the assembly is configured such that when the inner rod is in a failed state, the compression mechanism provides a force that moves the visual indicator toward the view port. In another embodiment, the assembly includes a proximity sensor in addition to, or in lieu, of a view port to detect a failure.

  • Patent number: 8393568
    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.
