SUBMERSIBLE ELECTROMECHANICAL DRIVE FOR ACTUATING MECHANISMS OF UNDERWATER FACILITIES Russian patent published in 1999 - IPC

FIELD: sea engineering; submersible electromechanical drives for pumps, revolving electrodes, etc. SUBSTANCE: submersible electromechanical drive has housing with electric motor, housing with output shaft of drive mounted in it and magnetic clutch used for connecting shaft of electric motor with output shaft of drive which is made in form of drive and driven magnetic rings located concentrically and separated by magnetopermeable sealing sleeve. Housing of electric motor and output shaft are interconnected by means of adapter bush forming hermetic outer and inner chambers of magnetic clutch between them. Outer chamber of magnetic clutch is filled with dielectric fluid and is used for placing drive magnetic ring fitted on shaft of electric motor. Inner chamber of magnetic clutch is filled with neutral fluid and is used for placing driven magnetic ring connected with output shaft of drive. Housing of electric motor is provided with end shaft on free side which forms hermetic chamber for electric joints filled with dielectric fluid. Output shaft of drive is provided with sliding spring-loaded electrode. EFFECT: possibility of compensating internal and external pressures in submersible electromechanical drive; enhanced reliability; ease in servicing; facilitated manufacture; reduced mass and overall dimensions; ecological safety of medium where drive operates. 6 cl, 1 dwg
