Abstract

898,163. Shafts. AUSTIN MOTOR CO. Ltd. Feb. 14, 1961 [Jan. 21, 1960], No. 2216/60. Class 80 (2). [Also in Group XXVI] A gas turbine rotor assembly including a coaxially driven compressor rotor 1 comprises a hollow shaft 9 having at one end a flange 14 locating the turbine disc 7 by a small contact area 8, 14A, a bearing 10 close to the flange, a coaxial sleeve 11 surrounding the hollow shaft 9 between the bearing and compressor hub, the sleeve 11 abutting the compressor rotor 1 and making a push fit on the shaft and means for axially clamping the rotor assembly. A shaft 3 supported at one end by a bearing 5 has a spigot 6 formed at the other end which is splined at 6A to the hollow shaft 9. A threaded rod 12 has serrations 17 on to which are fitted an internally serrated washer 18 having face splines 19 engaging splines 20 on the hub of the rotor disc 7A. This prevents twisting of the rod 12 when a castellated nut 13 is screwed home. A locking washer 21 is slotted to receive the splines 19 and has tabs which are folded to enter slots 22 in the nut 13 to be secured together at 23. In an alternative embodiment the hollow shaft extends through the compressor rotor disc and is journalled in the bearing 5. A clamping bolt, having a land locating in the bore of the shaft, has a flange which engages the bearing 5 and at the other end is tensioned and locked as in Fig. 1. An alternative nut locking washer for either type of bolt has internal serrations and fits under the nut 13. Two tabs fold along flats on the nut and are welded together over the end of the bolt. Specification 898,164 is referred to.
