FIELD: engines and pumps. ^ SUBSTANCE: proposed rotor of the steam or gas turbine comprises the blades arranged in several radial rows and made up of blade root fitted into the rotor, blade operating surface and rotary shroud. Open cuts are made in inclined surfaces of the aforesaid blade row shrouds. The cuts of adjacent shrouds form, in fact, a closed hollow space expanding radially along the rotor, first, to the maximum cross section and, then, narrows again. In every hollow space, a pin is fitted to move free. Note that the said pin maximum cross section is smaller than that of the hollow space and exceeds its minimum cross section. The said hollow space features a drop-like shape narrowing wedge-like from the maximum cross section. The angle at the wedge apex, formed by the inner surfaces of the hollows space cuts exceeds that at which the pin self-deceleration in the hollow space occurs. ^ EFFECT: higher reliability of rotor due to damping of vibrations originating in turbine operation. ^ 5 cl, 12 dwg |
