Patent number: 8491257Abstract: A method of assembling a crank arm (100, 200, 300) and vane assembly for a variable nozzle without requiring metallurgical bonding. In accordance with one aspect of the invention, the method comprises the steps of providing a vane assembly comprising a vane (120, 220, 320) joined to a vane shaft (110, 210, 310) that extends from the vane and terminates in a distal end (112, 212, 312), providing a recess (114, 214, 314) in an outer surface of the vane shaft at a location between the vane and the distal end, providing a crank arm (100, 200, 300) having an aperture (102, 202, 302) therein, inserting the distal end (112, 212, 312) of the vane shaft into the aperture (102, 202, 302) until the recess (114, 214, 314) in the vane shaft is inside the aperture, and causing a retaining member (104, 204, 304) associated with the crank arm (100, 200, 300) to engage the recess (114, 214, 314) in such a manner as to fasten the crank arm to the vane shaft in a substantially immovable manner.Type: GrantFiled: December 11, 2008Date of Patent: July 23, 2013Assignee: Honeywell International Inc.Inventors: Steven P. Martin, Christopher O. Meade, Patrick A. Rayner

Patent number: 8122716Abstract: An exemplary variable geometry turbine includes a turbine wheel; a variable geometry assembly that includes a rotatable control ring that has a slot and a plurality of vanes where each vane has a post pivotably controlled by rotation of the control ring and where adjacent vanes define nozzles to direct exhaust gas to the turbine wheel; a crankshaft that has a pin for receipt by the slot of the control ring where rotation of the crankshaft rotates the control ring; and a center housing that includes a rotatable stop fixed to the crankshaft and having a close stop surface, a secure component and a translatable shaft where the translatable shaft comprises an engagement mechanism to engage the rotatable stop; where translation of the shaft causes rotation of the crankshaft and where the close stop surface establishes a contact with the secure component to limit rotation of the crankshaft and to establish a closed limit for the vanes. Various other exemplary methods, devices, systems, etc., are also disclosed.Type: GrantFiled: June 4, 2008Date of Patent: February 28, 2012Assignee: Honeywell International Inc.Inventors: Patrick Rayner, Laurent Li, Songter Li

Patent number: 6925806Abstract: A variable geometry turbocharger assembly employing the present invention includes a center housing, a compressor housing attached to one side of the center housing, and a turbine housing attached to another side of the center housing. A plurality of movable vanes is disposed within the turbine housing, and a unison ring is rotatably disposed within the turbine housing to move the vanes in unison. The turbocharger includes a unison ring assembly of this invention that includes an insert that is separate from and attached to the center housing. The support has one or more surfaces to carry the unison ring, and the unison ring is rotatably positioned on the support. The support further provides a space that isolates the unison ring from making contact with contacting the center housing. A heat shroud optionally extends radially inwardly along the center housing and is retained into position by the support.Type: GrantFiled: April 21, 2004Date of Patent: August 9, 2005Assignee: Honeywell International, Inc.Inventors: Brent D. Zollinger, Patrick A. Rayner, Kevin P. Slupski
