VARIABLE VANE MECHANISM OF TURBOCHARGER HAVING PREDETERMINED VANE CLEARANCE

A method of manufacturing a variable vane mechanism includes arranging a vane and a spacer between a first support structure and a tool member of a tool. The method also includes abutting a first inner surface of the first support structure against a first side surface of the vane and a second side...

Beschreibung
Zusammenfassung:	A method of manufacturing a variable vane mechanism includes arranging a vane and a spacer between a first support structure and a tool member of a tool. The method also includes abutting a first inner surface of the first support structure against a first side surface of the vane and a second side surface of the vane against an opposing surface of the tool member, leaving a control surface of the spacer projecting from the first support structure at a predetermined distance. The method further includes fixedly attaching the spacer to the first support structure with the control surface of the spacer projecting from the first support structure at the predetermined distance. The method further includes abutting a second support structure on the control surface of the spacer to define a gap between the first support structure and the second support structure with the vane disposed within the gap.
