Abstract

A vane arm (22) includes a first end (70) and a second end (72); a shank (74) extending between the first end and the second end and having a first face (76) and a second face (78); a first hole (110) in the shank proximate the first end; a second hole (114) in the shank proximate the second end; a first tab (80) projecting laterally from the shank proximate the second end and having a bend (84) and a distal portion (90) distally of the bend; and a second tab (82) projecting laterally from the shank proximate the second end laterally opposite the first tab and having a bend (86), a distal portion (92) distally of the bend and partially overlapping the first tab distal portion. In one vane arm, a third hole (120) in the second tab distal portion overlapping a distal end edge of the first tab and having a proximal edge (122) and a distal edge (124). At least along a region across an axis (115) of the second hole (114), the third hole distal edge and proximal edge diverge from each other in a direction toward the first end. The first tab distal end edge and the third hole proximal edge diverge from each other in a direction toward the first end. In another vane arm, a hole (120) in the second tab distal portion overlapping a distal end edge of the first tab and having a proximal edge (122). At least along a region across an axis (115) of the second hole (114), the first tab distal end edge and the proximal edge of the hole provide means for uniquely angularly registering the vane arm to a shaft (42). Vane assemblies (20), a vane stage, as well as a method for using the vane arm are also provided.
