Patent number: 5779446Abstract: An air driven turbine having variable pitched blades is provided that includes a pitch change mechanism and associated control circuits for automatically adjusting the pitch of the blades during either rotating or non-rotating operational modes of the air driven turbine. The pitch control mechanism includes a resettable overspeed protection device which is directly actuated by an overspeed condition of the turbine and operates independently from the pitch change mechanism to move the blades to a failsafe, feathered, or coarse pitch, low speed position. The pitch control mechanism utilizes a linear actuator in the form of an acme screw drive. The air driven turbine includes a ball ramp thrust bearing for attaching the blades to a hub of the turbine in such a manner that during rotation of the turbine actuation loads on the pitch change mechanism are reduced.Type: GrantFiled: November 7, 1995Date of Patent: July 14, 1998Assignee: Sundstrand CorporationInventors: Jon B. Althof, Shan-Chin Tsai, Teddy L. Jones

Patent number: 5144851Abstract: The invention is directed to a jam tolerant ballscrew actuator. The ballscrew actuator is driven through a differential via plural power paths therein. A first of these differential power paths is drivingly coupled to a reciprocating dual ballscrew assembly by way of a rotatable ballnut. A second of the differential power paths is coupled to the dual ballscrew assembly via a rotatable hub having a splined opening therethrough. A reciprocating sleeve having a splined portion engages the sleeve shaft to reciprocate therethrough and be rotated by the rotatable hub. The sleeve shaft additionally includes a rotatable sleeve ballnut portion that drivingly cooperates with the dual ballscrew assembly. The reciprocating rotatable sleeve provides the ballscrew actuator output. The rotatable ballnut and the rotatable sleeve ballnut have equal but opposite leads which provide an axial motion summing characteristic for the dual ballscrew assembly.Type: GrantFiled: August 1, 1991Date of Patent: September 8, 1992Assignee: Sundstrand Corp.Inventors: Duane H. Grimm, Teddy L. Jones

Patent number: 4876906Abstract: A non-jamming electro-mechanical hydrostatic actuator system includes one embodiment in which a ballscrew assembly has a rotatable nut and an axially movable ballscrew. A motor rotates the nut to axially move the ballscrew. An actuator is operatively connected to a load to be actuated. A hydraulic system is coupled between the ballscrew and the actuator and includes a closed hydraulic circuit for statically trapping fluid in the circuit to effect movement of the actuator in response to movement of the ballscrew. The closed circuit is selectively opened to allow fluid flow in the circuit in the event of failure or jamming of the ballscrew assembly to allow reaction movement of the actuator in response to load forces. In another embodiment a rotary vaned assembly includes a cylinder housing a rotary vane, with the motor rotating the cylinder.Type: GrantFiled: November 20, 1986Date of Patent: October 31, 1989Assignee: Sundstrand CorporationInventor: Teddy L.

Patent number: 4770205Abstract: A bi-directional snub valve provides two parallel fluid paths therethrough and means for restricting the fluid flow through each of the parallel paths to one preferred direction. A movable piston is provided with two land portions which selectively are movable into blocking association with two openings in a fluid chamber. Blockage of either of the two openings in the fluid chamber and the corresponding fluid flow path does not effect the ability of the alternate path to conduct a fluid therethrough. The bi-directional snub valve therefore is able to slow the flow of fluid therethrough as a movable object approaches its end-of-travel position. However, because of the nature of the two parallel flow paths, the movable object can be moved away from its end-of-travel position at full speed. A cam arrangement is used to move the piston of the snub valve in response to movement of the movable object.Type: GrantFiled: May 4, 1987Date of Patent: September 13, 1988Assignee: Sundstrand CorporationInventors: Teddy L. Jones, Gary D. Gillingham, Jonathan E. Beimborn

Patent number: 4459867Abstract: This invention relates to a resettable force limiting assembly of the ball and screw type employed in a flight control actuation system. The resettable force limiting assembly includes a force transmitting reciprocating output member drivingly carried by an actuating member mounted for rotation in a housing. A reversible torque input is mechanically coupled to the actuating member to cause the output member to move in a direction dependent upon the direction of rotation of the input. A reciprocating reaction plate is secured for rotation with the actuating member. In operating cooperation with the reaction plate is a reaction plate engagement assembly that has elements secured against rotation to the housing. The elements are disposed on either side of the reaction plate. The elements have compression springs coupled thereto to resiliently separate the elements while allowing the elements to individually move towards and away from the reaction plate.Type: GrantFiled: December 28, 1981Date of Patent: July 17, 1984Assignee: Sundstrand CorporationInventor: Teddy L.
