CLUTCH FOR COUPLING ROTORS OF STEAM MACHINE Russian patent published in 2006 - IPC F16D1/33 

FIELD: mechanical engineering.

SUBSTANCE: clutch comprises flanges, studs mounted inside the centering bushings, which are arranged in the coaxial openings in the flange, and nuts positioned at the ends of the studs and provided with washers between them and bearing surfaces of the flanges. Between the centering bushings of both of the rotors at the site of the flange butt are the intermediate bushings. The intermediate bushings and washers are made of a material which changes its structure in response to the change of temperature condition, e.g. titanium nickelide, to define tensions in the connections of the intermediate bushings with the studs and openings in the flanges as well as in the connections of the washers with nuts and with bearing surfaces of the flanges.

EFFECT: simplified assembling and enhanced reliability.
