Abstract
This invention relates to an arrangement for the connection of two rotor disks of an axial-flow turbomachine arranged one behind the other, more particularly two turbine rotor disks of an aero-engine, in which connecting arms protruding from the rotor disks in the axial direction and facing each other are separably joined together by way of several bolts distributed along their circumference. According to the present invention, these bolts are arranged in the radial direction. In a preferential embodiment, each connecting arm features an alternation of prongs extending in the axial direction and of adjacent recesses, with the prongs of the connecting arm of one rotor disk engaging the recesses of the connecting arm of the other rotor disk. A retaining ring subdivided into individual ring segments lodges against the inner side of the connecting arms and is connected to at least one of the two connecting arms by means of bolts. The ring segments have a trapezoidal cross-section and, as viewed in the circumferential direction, their fronts lodge alternately against projections of the prongs, said projections extending inwards in the radial direction and embracing the ring segments.
