415216100 | With runner shaft of specific shape or material | 8 |
20080199313 | Method of manufacturing rotor and exhaust turbo-supercharge incorporating the rotor - Provided are a method of manufacturing a brazed rotor composed of a wheel and a shaft joined to the former by brazing, having a durability and a reliability which can be enhanced without increasing the manufacturing man hours, and a turbine rotor for an exhaust turbo-supercharger. The wheel having a disc portion formed at its outer periphery with blades, and a rod-like shaft are arranged in a furnace, being opposed to each other at their surfaces to be joined with a brazing solder being interposed therebetween, and infrared radiation is irradiated onto a side part of the wheel so as to heat the surfaces to be joined up to a temperature in a range from 1,000 to 1,080 deg. C. in order to melt the brazing solder, thereby the wheel and the shaft are joined by brazing to each other at their surfaces to be joined. | 08-21-2008 |
20080279684 | COMPOSITE SHAFT - A turbine shaft may be used to remove a heat load from pliant bearings without requiring the use of a process fluid for cooling the turbine shaft. The turbine shaft comprises a heat conductive sleeve disposed between an outer surface of a tie rod shaft and an inner surface of a bearing journal; the heat conductive sleeve having a sleeve inner surface separated from a sleeve outer surface by a sleeve thickness; the heat conductive sleeve having a first end separated from a second end longitudinally about a center axis; the sleeve outer surface being in physical contact with the inner surface of the bearing journal; and the heat conductive sleeve having a thermal conductivity that is greater than a thermal conductivity of the bearing journal. | 11-13-2008 |
20090263243 | Combustion Turbine Including a Diffuser Section with Cooling Fluid Passageways and Associated Methods - A combustion turbine includes a compressor section, a combustion section downstream from the compressor section, and a turbine section downstream from the combustion section. A diffuser section is downstream from the turbine section and has an outer wall, an inner wall, and at least one strut member extending therebetween. The outer wall has at least one first gas passageway therein, the inner wall has at least one second gas passageway therein, and the at least one strut member has at least one third gas passageway therein. The at least one first, second and third gas passageways deliver gas therethrough to assist attachment of a boundary layer to adjacent surfaces of the outer wall, the inner wall, and the at least one strut, respectively. | 10-22-2009 |
20100124495 | Turbine Engine Rotor Hub - A rotor has a central shaft having a central longitudinal axis. The rotor has a longitudinal stack of a plurality of disks surrounding the shaft. An aft hub couples the stack to the shaft. The aft hub has a proximal portion and a distal portion. The distal portion tapers at a lower characteristic half angle than does the proximal portion. | 05-20-2010 |
20100290904 | COUPLING FOR ROTARY COMPONENTS - A system is disclosed that includes a turbine engine having a first rotary component having a first annular coupling disposed about a rotational axis of the engine. The first annular coupling has an axially converging surface relative to the rotational axis. The system also includes a second rotary component having a second annular coupling disposed about the rotational axis of the turbine engine, wherein the second annular coupling comprises an axially diverging surface such that the axially converging surface of the first annular coupling mates with the axially diverging surface. | 11-18-2010 |
20110103947 | GAS TURBINE EXHAUST STRUT REFURBISHMENT - A gas turbine exhaust strut installed in an exhaust case of a gas turbine is disclosed which includes a trailing portion configured with an inner surface for mounting to an inner annular member of the exhaust case and an outer surface for mounting to an outer annular member of the exhaust case, a block attached to the trailing portion, an angled piece attached to the block and configured with a surface on a pressure side of the strut angled with respect to a surface of the trailing portion on the pressure side of the strut, and a transition piece attached to the block and configured with a surface on the pressure side of the strut for smoothing the transition between the height of the block on the pressure side of the strut and the height of the trailing portion on the pressure side of the strut. A method of refurbishing an exhaust strut installed in an exhaust case of gas turbine while retaining at least a portion of the strut in the exhaust case is also disclosed. An exemplary method includes removing a leading edge portion from a trailing portion of the strut, and attaching a replacement leading edge portion to the trailing portion of the strut. | 05-05-2011 |
20120020783 | SLINGER SHIELD STRUCTURE - A slinger shield structure is provided and includes a first annular disc, having a body, opposing faces defining an aperture extending through the body and through-holes extending through the body, which are arrayed around the aperture, a second annular disc having a body and opposing faces defining an aperture extending through the body, a hub for connection with the first and second annular discs at the respective apertures and radial vanes suspended between the first and second annular discs at a distance from the hub to define radial channels between adjacent radial vanes and drainage channels between the radial vanes and the hub. | 01-26-2012 |
20160377089 | Rotor for a Turbocharger Device, Turbocharger Device Having a Rotor, and Shaft for a Rotor of said Type - A rotor for a turbocharger device has a shaft and, arranged and fixed axially one behind the other on the shaft, an impeller wheel, a sealing bushing element and an axial bearing element which rotates with the shaft. The sealing bushing element and the axial bearing element, by way of an internal thread provided on at least one of the elements, are screwed to a first external thread arranged on the shaft and are braced against a shaft shoulder. Stronger and more rigid fixing of the parts that are pushed onto the shaft, and thus also lower susceptibility to vibration-induced faults during operation, are achieved by way of this construction. | 12-29-2016 |
