Abstract

662,302. Turbines and compressors. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM. July 11, 1949 [Sept. 22, 1948], No. 18325/49. Class 110(iii) The rotor of an axial-flow machine comprises axially-spaced discs 6 with integral axially extending flanges 7, 8 at different radii and connected together by an axial bolt 9 threaded through the discs and jamming the abutting flanges together. The bolt carries an external collar 10 abutting an internal collar on a part 13, and a screwed end engaging the threaded bore 11 of a part 14. The parts 13, 14 abut the flanges 7 on the end rotor discs. After it is tightened up the bolt is heated, the expansion being indicated on a gauge 20, and is again tightened and allowed to cool. The tensile strain is measured and controlled by a strain gauge 21 comprising an electric resistance wire. The flanges 8 may be welded together where they abut. A second axial bolt 22 has a head 23 engaging an internal collar 24 on the part 14 and a screwed end engaging the threaded flange 25 of a member 26 bolted to a coaxial machine. The bolt 22 may be tightened after heating. Specification 662,301 is referred to.
