TURBOGENERATOR STATOR Russian patent published in 1997 - IPC

Abstract RU 2074476 C1

FIELD: electrical and electromechanical engineering; manufacture of stators for operating turbogenerators. SUBSTANCE: stator has laminated core, end plates, bracing ribs mounting power storage cells incorporating shells with disk springs, pressure washers, pressure nuts; according to invention, shell is composite structure with intermediate ring. Pressure nut has toothed tip mounting retainer supported by pressure plate and secured to pressure nut by means of screw and cotter pin. EFFECT: improved reliability of operating turbogenerators maintained serviceable without high maintenance charges and labor consumption due to using power storage cells dispensing with additional mechanical treatment of pressure plate for their installation, additional expensive devices for checking compression force, welding operations for locking the pressure nut; provision for correcting compression forced during further operation of turbogenerator. 2 dwg
