Abstract

595,669. Securing together machine-parts for transmitting rotary motion. POWER JETS, Ltd., BONE, G. W., McLEOD, R. C., WATSON, K., and CALLISTER, T. E. April 27, 1942, No. 5653. [Class 80(ii)] [Also in Group XXVI] A centrifugal compressor rotor 23 and a turbine disc 10 are secured together by means accessible from the further side of the compressor. The compressor rotor 23 carries a quill-shaft 20 splined internally to engage external splines on a stubshaft 11 integral with the turbine rotor. The stub-shaft is secured in position by means of a screwed end 11B and a nut 26 which bears on a shoulder within the quill-shaft. The nut is part of a spindle 26B which passes through the rotor 23, is supported in a tearing plate 27 and can be rotated by means of external splines 26C. A shaft 30 provided for driving auxiliaries through a gear box 31 has internal splines 30A which engage the splines 26C and external splines 30C which engage splines on the hollow trunnion member 28 secured to the rotor 23, so locking the spindle 26B and providing a driving connection for the shaft 30. When the gear box is removed, the shaft 30. may be drawn to the left to disengage the splines 30C from the splines on the trunnion member and other splines 30B then engage the splines 26C. In this condition the shaft 30 can be used to rotate the spindle 26B and separate the nut 26 from the stub-shaft. The shaft 28 is mounted in a fixed thrust bearing 29. The stubshaft is mounted in a bearing 12 supported in a sleeve 13 splined to the interior of a fixed bush 15.
