International Classification:

F16J 1544

US Classification:

277355, 277416

Abstract:

A seal arrangement for a rotary machine, such as a turbine, includes a main seal segment such as a labyrinth seal segment, a brush seal segment disposed in a slot in the main seal segment and having a layer of bristles secured between upstream and downstream plates of the brush seal segment, and at least one passage radially formed through the main seal segment to communicate a balancing pressure from a pressure source located exteriorly of an outer periphery of the main seal segment to a cavity defined in the downstream plate of the brush seal segment at a downstream side of the layer of bristles of the brush seal segment.

International Classification:

F16J 15447

US Classification:

277355

Abstract:

A brush seal assembly is radially and axially repositionable relative to stationary and rotating components. Shim packs whose thickness can be reduced by peeling adhesively attached foil layers from the shim packs are used to provide both axial and radial repositioning. In another form, a plurality of set screws may be threaded into a mounting member for the brush seal assembly to controllably space the brush seal from the rotating component. In a further form, an eccentric cam is rotated to reposition the brush seal assembly radially inwardly or outwardly with shim packs being used to reposition the brush seal in an axial direction.

International Classification:

F01D 530

US Classification:

416215, 416222

Abstract:

A turbine closure bucket adapted to complete assembly of a row of tangential entry buckets on a rotor wheel includes an airfoil portion and a mounting portion for mounting the bucket to a turbine wheel. The mounting portion has front and back faces, with weight reduction cavities formed internally in the front and back faces. Externally, the front and back faces of the closure bucket are substantially identical to front and back faces of adjacent buckets in the row.

International Classification:

F01D 532

US Classification:

416222, 416239, 416248

Abstract:

A multiple hook dovetail connection for connecting a rotor wheel and a bucket for a turbine rotor that permits the use of wider vanes at the ends of the buckets without changing the size of the wheel and the other existing components of the turbine. The dovetail connection comprises a male dovetail component and a female dovetail component. The male dovetail component includes a plurality of hooks. Each of the hooks includes a crush surface, a neck and an angle formed between the crush surface and the neck. These books are dimensioned in accordance with at least one of the included tables.

Appl. No.:

09/639047

Inventors:

George Ernest Reluzco - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

F01D 514

US Classification:

416241R, 416215, 416219 R

Abstract:

A steam turbine wheel has a male dovetail projecting about its peripheral margin and a gap in the margin. Buckets having bases with complementary female dovetails are disposed in the gap and register with the male dovetail of the wheel, enabling the buckets to slide about the wheel into positions stacking the bases of the buckets against one another. The final three buckets including a closure bucket are disposed about the wheel margin with two buckets straddling the closure bucket secured to the wheel margin by the dovetails. The closure bucket is secured to the straddling buckets by axially extending pins. The closure and straddling buckets, as well as the pins, are formed of materials having a higher creep rupture strength than the materials forming the remaining buckets, enhancing the capability of the closure bucket to withstand high temperature and stresses over time without creep.

International Classification:

F01D 508

US Classification:

4151742, 29889

Abstract:

An insert assembly is provided for a rotary machine wherein the rotary machine comprises a rotor and a casing. The rotor comprises a generally longitudinally-extending axis. The casing is generally coaxially aligned with the axis. The casing circumferentially surrounds and is radially spaced apart from the rotor. The insert assembly comprises a channel circumferentially disposed on the rotor and an insert circumferentially disposed in such channel such that the insert assembly is configured to thermally isolate frictional heat from the rotor to the insert.

Assignee:

General Electric Co. - Schenectady NY

International Classification:

F04D 2944

US Classification:

4152092

Abstract:

The turbine includes inner and outer rings and partitions mechanically connected therebetween. In one form, the partitions have connecting elements at tip and root portions of the vanes which are received in complementary grooves in the outer and inner rings, respectively. The partitions in one form are stacked against one another and secured by end lugs at the diaphragm joints. In another form, the partitions are pinned to the outer and inner rings with spaces between the connecting elements to avoid accumulation of tolerances. In a third form, the partitions are applied against the outer and inner rings in an axial direction and retainer plates are bolted to the outer and inner rings to secure the partitions in the diaphragm assembly. In all cases, the diaphragm is formed without welding.
