Abstract

1,149,513. Bearings. ROLLS-ROYCE Ltd. 7 Sept., 1967 [6 Oct., 1966], No. 44764/66. Heading F2A. [Also in Division F1] A bearing assembly comprises at least one bearing which is supported from fixed structure by means of two axially-spaced substantially radially extending annular panel members, at least one of the panel members having at least a portion thereof which is dished or which is secured to at least one dished member, the panel members being braced and interconnected by means of the or each dished member or portion. In an embodiment a gas turbine jet propulsion engine 10, Fig. 1, has an engine casing 11 within which are mounted in flow series a low-pressure compressor 12, a highpressure compressor 13, combustion equipment 14, a high-pressure turbine 15, a number of angularly spaced-apart hollow nozzle guide vanes 16, a low-pressure turbine 17 and an exhaust duct 18. The high-pressure turbine 15 drives the high-pressure compressor 13 by means of a shaft 21, Fig 2, and the lowpressure turbine 17 drives the low-pressure compressor 12 by means of a shaft 22, the shaft 21 being mounted concentrically within the shaft 22. The shafts 21, 22 are mounted in roller bearings 24, 25 respectively and the latter are supported by means of a ring 26. The ring 26 is supported from the casing 11 by means of annular members 30, 31, the latter being welded at 32, 33 to the ring 26 and at 34, 35 to a strut 36. The struts 36 are angularly spaced-apart and each pass through a hollow nozzle guide vane 16 to be bolted to the casing 11. The members 30, 31 have holes 40 or 41 which have dished members 42 or 43 welded therein. The dished members, which may be circular or elliptical, have bases 44, 45, the latter being welded together. A number of angularly spacedapart holes may be formed in the members 30, 31 so that several pairs of dished members may be introduced. Instead of pairs of dished members, single dished members may be used, their bases being welded to one annular member 30 or 31 and their edge portions welded to the other annular member. In a modification annular members 30a, 31a, Fig. 3 are each provided with a corrugated portion 46.
