Abstract
Official abstract text for this publication.
In a rotating electric machine with shaft-seal devices mounted thereon, an object to provide them is to uniformize a temperature distribution of a sealing ring with a simple structure. The rotating electric machine with the shaft-seal devices mounted thereon includes a rotor having a shaft; a stator disposed in a circumferential surrounding of the rotor; a sealing ring having a plurality of through holes formed therein, being disposed in a circumferential surrounding of the shaft; a gland seal having an oil supply opening therein, for enclosing a circumferential surrounding of the sealing ring; a partition plate disposed between the sealing ring and the gland seal; and a housing on which the gland seal is fixed, for accommodating the rotor and the stator.
First claim
Opening claim text (preview).
1 - 7 . (canceled) 8 . A rotating electric machine with shaft-seal devices mounted thereon, comprising: a rotor having a shaft; a stator disposed in a circumferential surrounding of the rotor; a sealing ring having a plurality of through holes formed therein, being disposed in a circumferential surrounding of the shaft; a gland seal having an oil supply opening therein, for enclosing a circumferential surrounding of the sealing ring; a partition plate disposed between the sealing ring and the gland seal; and a housing on which the gland seal is fixed, for accommodating the rotor and the stator, wherein the partition plate opposes to the oil supply opening formed in the gland seal. 9 . The rotating electric machine with shaft-seal devices mounted thereon as set forth in claim 8 , wherein a channel is formed along on an inner circumferential side of the gland seal, and the partition plate is inserted into the channel. 10 . The rotating electric machine with shaft-seal devices mounted thereon as set forth in claim 8 , wherein the partition plate surrounds the sealing ring in the entire circumference thereof. 11 . The rotating electric machine with shaft-seal devices mounted thereon as set forth in claim 10 , wherein a plurality of oil-amount adjustment holes is opened in the partition plate. 12 . The rotating electric machine with shaft-seal devices mounted thereon as set forth in claim 11 , wherein the oil supply opening is disposed to avoid a position where the plurality of oil-amount adjustment holes is viewable directly below the oil supply opening. 13 . The rotating electric machine with shaft-seal devices mounted thereon as set forth in claim 12 , wherein the plurality of oil-amount adjustment holes takes on a feature in which the more distant the oil-amount adjustment holes are from the oil supply opening formed in the gland seal, the larger their sizes become.
