Embodiment Construction

[0041] The present invention will be described with reference to rotating hardware of the type used in high-bypass gas turbine engines, but it should be understood that the teachings and benefits of the present invention are applicable and applicable to a wide variety of applications.

[0042] Figure 4 A partial cross-sectional view of a supercharger shaft or rotor 30 of the type used in the compressor section of a high bypass gas turbine engine is schematically represented. Similar to the prior art rotor 10 shown in FIG. 1 , the rotor 30 includes a rim 32 positioned in a radially outward direction from a plurality of rotating discs (wheels) 34 that Innermost includes hole 36 and includes a relatively thin web 38 between rim 32 and hole 36 . Rim 32 has features 40 suitable for securing compressor blades (not shown), and annular seals 42 between blade stages. Bore 36 of runner 34 enables rotor 30 to be mounted to a shaft (not shown) driven by the turbine section of the engin...

Abstract

The present invention relates to rotating hardware and a process therefor, concretely provides a process of fabricating rotating hardware and rotating hardware formed thereby. The process includes fabricating at least two members that together define at least two portions of a component. Each member has an interface surface at which the members can be joined to locate a first of the portions in a radially outward direction from a second of the portions. The members are joined together so that the interface surfaces thereof form a joint interface located within a pad region that has a axial thickness that is greater than a contiguous region of the component. The joint interface is not perpendicular to the axial and radial directions of the component. The pad region is defined by embossments that are offset from each other in the radial direction of the component so as to partially but not completely overlap each other in the axial direction of the component.

Description

technical field [0001] The present invention generally relates to manufacturing methods including joining operations. More particularly, the present invention is directed to a technique for manufacturing rotating hardware, such as rotating components of a turbomachine, the joining techniques used in their manufacture, and the hardware formed therefrom. Background technique [0002] Components in the combustor and turbine sections of gas turbine engines are often formed from superalloy materials in order to achieve acceptable mechanical properties at the high temperatures caused by the hot combustion gases generated in the combustor. Higher compressor outlet temperatures in modern high pressure ratio gas turbine engines can also necessitate the use of high performance superalloys for compressor components, including spools, rotors, and other components. The appropriate alloy composition and microstructure for a given component depends on the specific temperatures, stresses, ...
