Attachment stud for a variable vane assembly of a turbine compressor
First Claim
1. An attachment system for a variable vane assembly, the variable vane assembly including a synchronizing ring coupled to a lever arm by an attachment stud, the variable vane assembly further including a rotational attachment devices configured to rotatably couple the lever arms with the synchronizing ring, the attachment stud comprising:
- a bottom segment having a shape and configuration adapted to be secured to the synchronizing ring;
a middle segment having a shape and configuration adapted to receive the rotational attachment device;
a shoulder segment disposed between the bottom segment and the middle segment; and
a top segment having a shape and configuration adapted to receive a retaining device configured to rigidly attach the rotational attachment device to the attachment stud.

Abstract
An attachment stud for a variable vane assembly is disclosed. The attachment stud may generally include a bottom segment, a middle segment, a top segment and a shoulder segment. The bottom segment may generally have a shape and configuration adapted to be secured to a synchronizing ring of the variable vane assembly. The middle segment may generally have a shape and configuration adapted to receive a rotational attachment device of the variable vane assembly. The shoulder segment may be disposed between the bottom segment and the middle segment. The top segment may generally have a shape and configuration adapted to receive a retaining device configured to rigidly attach the rotational attachment device to the attachment stud.
