ELECTRIC GENERATOR Russian patent published in 2004 - IPC

FIELD: mining industry.

SUBSTANCE: device has device for its supporting, outer rotor with turbine, mounted through bearing on axis, together with which inner stator is made. Inner rotor and outer stator form a hollow, wherein a pressure and temperature expansion of oiling liquid compensator is placed with possible axial displacement, made in form of piston compacted near rotor and axis. Piston is compacted along axis by rubber reinforced collar, mounted inside compensator with possible axial displacement with it. On axis within displacement range of piston a detachable bushing may be mounted, which may be restricted from rotation. Near rubber reinforced collar an additional rubber reinforced collar may be mounted, while elastic elements of both collars are directed to opposite sides with forming of hollow between them. Hollow between rubber collars may be filed with consistent oil.

EFFECT: higher reliability and simplified maintenance and construction.
