Patent number: 8033785Abstract: Several physical features on an inlet guide vane (IGV) ensure proper orientation of the IGV within a compressor during assembly. A gear with several teeth removed results in a flat surface on the gear which inhibits the gear from rotating on the rack of the compressor inlet casing. An orientation pin is located in the internal bore of the gear. The cylindrical IGV spindle has a portion formed as a flat surface and the orientation pin engages this flat surface. These features are applicable to both a one-piece IGV where the jackshaft is integrated with the IGV stem and a two-piece IGV in which the jackshaft is separate from the IGV stem. A feature applicable to a two-piece IGV is a shaped boss on the IGV stem that allows the jackshaft to be located on the IGV stem in only one orientation.Type: GrantFiled: September 12, 2008Date of Patent: October 11, 2011Assignee: General Electric CompanyInventors: Anthony Constantine Thermos, Stephen Paul Wassynger, Carlos Alberto Collado, Ajay Gangadhar Patil, Cj Silver
