Abstract

783,970. Turbines. NAPIER & SON, Ltd., D. Aug. 9, 1955 [Sept. 17, 1954], No. 27051/54. Class 110 (3). [Also in Group XXXIV] A turbine rotor bearing mounted in a housing surrounded by an annular passage and having the housing supported from the outer circumferential wall of the annular passage by at least three radial supporting members secured at their inner ends to the housing and passing through guides rigid with the outer wall in which they can slide radially only has the outer ends of the supporting members connected to the outer wall by flexible diaphragms lying in planes normal to the lengths of the supporting members. The turbine rotor shaft D is supported by a ball bearing F mounted in a twopart housing F<SP>1</SP>, F<SP>2</SP>. The outer wall B<SP>1</SP> of the annular outlet passage B is connected to the turbine casing A and the bearing housing F<SP>1</SP> is supported from the outer wall B<SP>1</SP> by four tubular radial supports G. Each support G is screwed at one end into a boss F<SP>3</SP> formed on the housing F<SP>2</SP> and at the other end slides in a tubular screening member J which is rigidly mounted in a boss H forming part of the wall B<SP>1</SP>. The member J extends across the outlet passage B and screens the support G from the heat of the gases. Each of the bosses H is surrounded by an annular wall H<SP>1</SP> to which is secured the edge of a flexible diaphragm G<SP>2</SP> the centre of which is secured to the wall of a chamber K which is rigidly attached to the support G. The flexibility of the diaphragm allows for free radial expansion of the support. Cooling air is admitted to the chamber K through the passage K<SP>1</SP> and from the chamber passes through the support G to a chamber L. From the chamber L cooling air is supplied to the bearings and the chamber enclosing the disc D<SP>1</SP>. Some of this cooling air may pass through the shaft D to cool other discs. This air may be used to apply air pressure to one face or more of the discs to balance the axial thrust on the turbine blades. Reference has been directed by the Comptroller to Specifccation 623,615.
