Abstract

749,178. Radial-flow turbines and compressors. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM. June 30, 1954, No. 19177/54. Class 110(3) In a radial-flow steam or gas turbine or compressor in which blades 1 are mounted between strengthening rings 2, 3 one of which is formed with an extension 4 constituting a flexible annular member connected to a rotor disc 5 or 6 of the turbine or compressor, the said strengthening ring, 3, is formed with an axial or radial annular recess 8 so as to form a U-section. One of the prongs or legs of the U-section is formed with an annular extension 4, so that the total length of the prong or leg and the flexibility thereof is increased without increasing the distance between the two rotor discs. Two or more radially projecting leakage-preventing strips are mounted on either the outer or inner circumferential surface of the strengthening rings. The axially outermost leakage-preventing strip is located axially outside the bottom of the annular recess 8 on a peripheral surface of the strengthening ring which is not affected by the recess. The unsupported strengthening ring 2 is formed with a similar annular recess 8.
