LUBRICATING SYSTEM OF TELEMETERING-SYSTEM POWER GENERATOR Russian patent published in 2005 - IPC

FIELD: lubrication of telemetering-system power generator.

SUBSTANCE: proposed lubricating system of telemetering-system power generator has priming device on its front end, space filled with lubricant disposed between external rotor incorporating at least one turbine casing installed through front and rear bearings on stator provided with shaft, and lubricant thermal expansion device made in the form of spring-loaded piston mounted inside rotor for axial displacement; piston is installed between turbine casing and bushing, and the latter is installed and secured in position within turbine casing; end-seal pair contacts bushing but-end. One of parts incorporated in end-seal pair has slots and round holes and other part has mating projections with longitudinal slots opposing mentioned holes; junction pins are passed through these slots and holes. Springs are installed between two parts of end seal. Bushing is locked by end projections in slots of intermediate ring whose outer surface carries pin that enters slit in turbine casing. Through slots are made on bushing end. Adjusting ring that functions to vary pressure in end seal is inserted between rotor and front bearing.

EFFECT: enhanced operating reliability of end-seal pair and lubricant thermal expansion device.
