Horizontal joint for a rotary machine and method of assembling same

Abstract

A horizontal joint of a rotary machine barrel includes first and second section mating surfaces that extend axially adjacent to the joint, and a plurality of gaps and a plurality of tangs disposed axially along the first and second section mating surfaces, respectively. Each tang has an axially extending tang aperture defined therethrough. Each gap is sized and axially spaced to receive a corresponding tang. Additionally, the joint includes a plurality of mating surface segments defined along the first section mating surface. Each segment extends axially between a corresponding pair of gaps and has an axially extending segment aperture defined therethrough. The tang apertures and segment apertures align to form a generally continuous axial pin aperture when the second section mating surface is positioned against the first section mating surface.

Description

BACKGROUND[0001]The field of the disclosure relates generally to a horizontal joint for a rotary machine, and more particularly to a rotary machine horizontal joint coupled together by an axial pin.[0002]At least some known rotary machines, such as some known gas turbines, include a generally tubular inner barrel that circumscribes a rotor assembly, and a generally tubular outer barrel that circumscribes the inner barrel. A gas flow path may be defined in a generally annular space between the inner and outer barrels. Moreover, in at least some such rotary machines, an upper section and a lower section of the inner barrel and / or an upper section and a lower section of the outer barrel are coupled together along a pair of horizontal joints that extend axially along opposing sides of the inner barrel. The upper and lower sections each include a flange that extends along each horizontal joint. A plurality of bolt holes are defined at cooperating locations in each upper and lower flange,...

AI Technical Summary

Benefits of technology

The patent describes a way to join two sections of a rotary machine's barrel together using a horizontal joint with tangs and gaps. The tangs have certain properties and the gaps are positioned to match up with the tangs. This creates a continuous axial pin aperture that allows for the insertion of an axial pin. The patent also describes an exhaust frame that has a first and second section with tangs and gaps that align to create the continuous axial pin aperture. The technical benefits include improved structural integrity and alignment for the rotary machine's parts.

Problems solved by technology

The interior of the inner barrel typically presents a difficult workspace in which to maneuver, increasing a time required for maintenance and a cost.

Therefore, a need to facilitate personnel entry into the interior of the inner barrel may increase a size and manufacturing cost of the rotary machine.
