Abstract
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.
