Abstract
728,754. Securing together rotor parts. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. May 28, 1953 [May 30, 1952; Oct. 21, 1952], Nos. 13774/52 and 26460/52. Class 80 (2). [Also in Group XXVI] A bladed rotor for a compressor or turbine comprises two sheet metal, coaxial, axiallyspaced discs having a row of rotor blades attached to their peripheries and axiallydirected, annular flanges are disposed on the adjacent faces of the discs radially inwardly of their peripheries, the flanges being constituted by the axially-extending arms of annular brackets which have radially-extending arms rigidly secured to the disc faces, the flanges being fastened together to clamp the blade roots between the disc peripheries. In Fig. 1, a rotor element comprises a pair of discs 1, 2 having their peripheries formed with flanges la, 2a which are reinforced by rings 6, 7. The roots 12 of a row of blades 11 are held between the flanges. Flanged rings 3, 4 are secured to the adjacent faces of the discs and are reinforced by rings 9, 10 and the two discs are secured together by means of a shrunk-on ring 5. The adjacent discs 2, 1 of adjacent pairs of rotor elements are similarly connected together, the surface of the rotor between adjacent rotor elements being completed by means of rings 26, the ends of which engage the notches in the blade roots. In a second embodiment, the rings 3, 4 are formed with screw threads on their outer surfaces, the: two flanges being connected together by means of an internally-screwed ring member. In Fig. 3, the discs 1, 2 have flanges 3, 4 which are in screw-threaded engagement with each other. Adjacent discs of adjacent pairs of rotor elements are similarly connected together. Specification 724,123, [Group XXVI], is referred to.
