| 20100272561 | Boltless Multi-part Diaphragm for Use with a Centrifugal Compressor - A diaphragm assembly of a centrifugal compressor includes a return channel wall having a generally ring-like shape; a vane assembly having a plurality of vanes formed integrally with at least one ring-shaped track having a rail structure extending therefrom; and a diaphragm wall having a generally ring-like shape and at least one groove extending around a circumference thereof. The vane assembly is fixedly coupled to the return channel, thereby forming a return channel assembly. The return channel assembly is coupled to the diaphragm wall by sliding the rail structure into the at least one groove of the diaphragm wall. | 10-28-2010 |
| 20100172745 | CENTRIFUGAL COMPRESSOR HAVING ADJUSTABLE INLET GUIDE VANES - An apparatus for adjustment of inlet guide vanes of a compressor includes a ring having a plurality of slots spaced around a circumference thereof; a plurality of lever arm assemblies each having a pin that includes a body with a first end and a second end and a lever arm extending perpendicularly from the second end of the body of the pin; a plurality of vanes each coupled to an end of one of the plurality of lever arms by a shaft; and a rack and pinion drive mechanism. The pin of each of the lever arm assemblies is configured to be positioned within each of the plurality of slots such that the first end of the pin extends into the slot. The rack and pinion drive mechanism includes a pinion coupled to the shaft of one of the plurality of vanes, thereby creating a drive vane; and a driven rack operationally coupled to the pinion. The drive vane is configured to rotate the ring via the rack and pinion drive mechanism, thereby adjusting an angular position of the plurality of vanes. | 07-08-2010 |
| 20100037462 | METHOD OF POSITIONING A BEARING ASSEMBLY AND CENTERING SUPPORT STRUCTURE THEREFOR - The bearing assembly is intended for application with rotor shafts in turbomachinery. The bearing assembly includes an annular bearing in which the shaft is disposed and a support structure for supporting the bearing. The bearing support is mounted about and radially supports the bearing. The bearing support at least in part defines a squeeze film annulus of the bearing assembly. A plurality of centering elements is associated with the bearing and bearing support and act to center the bearing within the squeeze film annulus. The centering elements are provided at radially spaced locations around the bearing. The centering elements may also be cylinder springs provided at uniformly spaced locations around the bearing. The centering elements may additionally be load cell springs provided at uniformly spaced locations around the bearing. In an alternative embodiment, a singular annular wave spring may be provided in place of the plurality of centering elements. | 02-18-2010 |
| 20090180858 | Method to Prevent Brinelling Wear of Slot and Pin Assembly - A method to prevent brinelling wear of a slot and pin assembly of an adjustable inlet guide vane mechanism includes: providing a compressor having the adjustable inlet guide vane mechanism including a control ring with a plurality of tapered slots positioned around a circumference of the control ring; providing a plurality of tapered pin/lever arm assemblies each comprising a tapered pin having a tapered body with a first threaded end and a second end, a lever arm extending perpendicularly from the second end of the tapered body of the tapered pin and a vane coupled to an end of the lever arm; positioning the tapered pin of the tapered pin/lever arm assembly within each of the plurality of tapered slots such that the first threaded end of the tapered body of the tapered pin extends through the tapered slot; positioning a washer and spring over the first threaded end of the tapered pin of each of the tapered pin/lever arm assemblies; and securing the tapered pin of each of the tapered pin/lever arm assemblies within each of the tapered slots by coupling a nut to the first threaded end of the tapered pin of each of the tapered pin/lever arm assemblies. The tapered body of the tapered pin of each of the tapered pin/lever arm assemblies and each of the plurality of tapered slots are shaped to ensure contact between the tapered body of the tapered pin and the tapered slot thereby preventing brinelling wear. | 07-16-2009 |
| 20090068006 | Tilted Cone Diffuser for Use with an Exhaust System of a Turbine - An exhaust system for a turbine includes an annular diffuser and a collector. The annular diffuser is positioned adjacent to a final stage of the turbine and includes a hub portion surrounding a turbine shaft and an outer cone having a substantially frusto-conical shape that is radially symmetrical about a central longitudinal axis thereof that is tilted relative to the turbine shaft. The collector has an inlet extending from the annular diffuser and an outlet. The collector is configured to include a turn that causes the collector to turn exhaust gases approximately 90° from the longitudinal axis of the turbine shaft. The outer cone of the annular diffuser is tilted in a direction of the turn of the collector. | 03-12-2009 |
