ROTARY MACHINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed machine contains two rotors. Flexible shaft of one of rotors passes inside other rotor. Bead is formed in middle of shaft length. Shaft dynamic deflection limiter is installed on inner surface of outer rotor. Said limiter consists of ring whose inner surface forms, with outer surface of shaft bead, a ring clearance between surfaces composing antifriction pair. Surface of outer rotor limiting relative displacement of rotors is formed by ends of spring wires assembled into bundles uniformly spaced over circumference. EFFECT: increased service life of rotary machine, reduced mass and overall dimensions of machine. 3 dwg
