Patent number: 8491257
Abstract: 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.
