Abstract

1430864 Shaft couplings W E WOOLLENWEBER 6 April 1973 16520/73 Heading F2U [Also in Division F1] The invention relates to a rotatable assembly comprising two vaned wheels mounted on a common shaft and is described with reference to a turbine compressor assembly such as a turbo-charger for an I.C. engine which comprises a turbine wheel 14 and a compressor wheel 18 mounted on a common shaft 22. The shaft 22 is formed integrally with the turbine wheel 14, the other end of the shaft having a threaded portion 56 which engages a threaded core in the hub of the compressor wheel. A sleeve 66 is disposed around the shaft between the two wheels whereby the shaft is placed in tension by the screwed connection. The shaft is provided also with an unthreaded extension 60 which engages in an unthreaded extension of the bore in the hub of the compressor wheel for location purposes. A further sleeve 68 is disposed round the sleeve 66 and forms the inner race of a pair of ball-bearings. The shaft 22 is formed with a portion 64 of reduced diameter so as to reduce heat conduction along the shaft.
