FLUID-FILLED ELECTRICAL MACHINE Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: fluid-filled electrical vertical-shaft electrical machines are joined together through flanges, fastenings, and shafts, and sealed with aid of sealing ring. Top flange of machine has two rows of bolts inserted from underside. Bolt heads of one row are spaced from bottom flange through distance shorter than depth of coupling of shafts of two machines; bolt heads of second row are spaced through distance longer than depth of coupling of two shafts. Bottom machine flange has projection inserted in flange of other machine and sealed with aid of ring placed at distance longer than that between bottom machine flange surface and bolt heads of second row relative to joint between two flanges. EFFECT: improved reliability due to elimination of uncoupling of the shafts of two vertical machines while retaining tightness of their joint. 1 dwg
