20140270737 | BEARING ARRANGEMENT INNER RACE HEATER - A device for heating a bearing race mounted on a shaft including a quartz halogen lamp for heating the bearing race and a reflector for reflecting heat from the quartz halogen lamp towards the bearing race. | 09-18-2014 |
20150026964 | METHOD FOR REBALANCING GENERATOR ROTOR IN-SITU - A method for servicing a rotor of a generator includes the steps of, dismantling a non-drive end of the generator, removing insulation from portions of an existing Wye ring and existing connection lugs, removing portions of the existing Wye ring near the existing connection lugs, installing a replacement Wye ring in the generator, connecting the replacement Wye ring to the existing connection lugs, and insulating the replacement Wye ring and the existing connection lugs. The method is performed on the generator in-situ. | 01-29-2015 |
20150026965 | SYSTEM AND METHOD FOR REBALANCING GENERATOR ROTOR IN-SITU - A system for rebalancing a generator rotor includes a temporary bearing shield configured to support a non-drive end of the generator rotor, and a pony motor assembly configured for attachment to a drive end of the generator rotor. The pony motor assembly is configured to rotate the generator rotor during a rebalancing operation. The temporary bearing shield and the pony motor assembly enable the generator rotor to be rotated during an in-situ rebalancing operation. | 01-29-2015 |
20150028703 | SYSTEM AND METHOD FOR REBALANCING GENERATOR ROTOR IN-SITU - A Wye ring system for a rotor of a generator includes a replacement Wye ring configured to replace an existing Wye ring serving as a floating neutral connection in the rotor. The replacement Wye ring is positioned radially inside the existing Wye ring and co-axial with the rotor. A fastening system is configured for mechanically and electrically connecting the replacement Wye ring to a plurality of connection lugs. The plurality of connection lugs are electrically connected to the rotor windings. The replacement Wye ring replaces the floating neutral connection of the existing Wye ring. | 01-29-2015 |
20150059163 | SYSTEM AND METHOD FOR CENTERING WYE RING IN-SITU - A wye ring centering system and method are provided. The system includes a plurality of rollers configured for contacting a wye ring, and a plurality of mounting fasteners configured for supporting the plurality of rollers. Each of the mounting fasteners is configured to pass through a fan hub. The plurality of rollers and the plurality of mounting fasteners are distributed at substantially equal intervals around the fan hub. The wye ring is placed over the plurality of rollers to center the wye ring around a shaft. | 03-05-2015 |
20150059183 | METHOD OF REMOVING A BEARING FROM A SHAFT - A method of removing a part from a shaft is provided. The part is attached to the shaft with an interference fit. The method includes the steps of, inserting an expandable plug into the shaft, and adding coolant to an interior of the shaft. The coolant cools the shaft from the interior of the shaft to an exterior of the shaft. Another step removes the part from the shaft. The part is removed from the shaft without sustaining damage to either the part or the shaft, so that the part and the shaft may be refurbished or reused. | 03-05-2015 |
20150101180 | METHOD AND SYSTEM FOR REPAIRING OR SERVICING A WYE RING - A method for repairing or servicing a wye ring of a generator includes the steps of, dismantling the generator to gain access to the wye ring, determining a fault location in the wye ring; and attaching a patch to the wye ring in an area of the fault location. The patch provides an electrical path around the fault location so that the generator is repaired. | 04-16-2015 |
