Abstract

800,524. Securing together compressor rotors. SVENSKA TURBINSFABRIKS AKTIEBOLAGET LJUNGSTROM. Oct. 8, 1956 [Nov. 23, 1955], No. 30573/56. Class 80 (2). [Also in Group XXVI] An axial-flow compressor rotor comprises two units each comprising blade-carrying discs 2 and spacer rings 3, 4 which are clamped together by a hollow tie-bolt 5 threaded at one end into a journal 6 and provided at the other end with a flange engaging a ring 8 bearing against an adjacent disc 2. The two units and a spacer sleeve 9 are clamped together by a preferably tubular tie-bolt 10 extending through the hollow tie-bolts 5 and threaded at one end into one journal 6 and engaging the other journal 6 by means of a flange 11. A sleeve 12 may be provided, with axial play but with torque-transmitting engagement with the rings 8. Torquetransmitting pins 13 extend through the whole or a part of each unit. The spacer rings may comprise flanges formed integrally with the discs 2.
