Abstract
A top guide to shroud head interface is described. In one embodiment, the interface includes a top guide that includes a flange that is configured to engage a corresponding flange of the shroud head. The top guide flange includes a plurality of frusto-conical shaped guide pins extending from the top surface of the flange. The shroud head flange includes a plurality of guide pin openings configured to align with the guide pins located on the top guide flange. Each guide pin opening includes a frusto-conical portion that extends through the flange from the bottom surface of the shroud head flange and has a slope equal to the slope of the frusto-conical pins. Each guide pin opening also includes a cylindrical portion that extends from the small base of the frusto-conical portion of the guide pin opening to the top surface of the shroud head flange. The diameter of the frusto-conical guide pin opening at the bottom surface of the shroud head flange is configured to be larger than the diameter of the frusto-conical guide pin immediately adjacent the top surface of the top guide flange. The frusto-conical guide pins and guide pin openings provide for suitable clearances between the guide pins and the guide pin openings to accommodate any flexing of the shroud head flange during installation.
