Abstract

989,333. Securing together rotary parts. ROLLS-ROYCE Ltd. Feb. 20, 1964, No. 7243/64. Heading F2U. In a gas turbine engine, an H.P. compressor and turbine shaft 11 supported in a ball bearing 12 for limited axial movement drives an auxiliary shaft 18 through splines 22, a sleeve 20, splines 21, an intermediate shaft 13 mounted on the shaft 11 and held against axial movement by a ball thrust bearing 15, a bevel gear 16 on the intermediate shaft, and a bevel gear 17 on the shaft 18. Bearing bushes 14 allowing relative axial movement of the shafts 11, 13 are split to permit differential expansion between themselves and either of the shafts 11, 13, and are of porous metal, e.g. porous bronze, impregnated with a synthetic resin material, e.g. P.T.F.E., having a low coefficient of friction in the unlubricated state. The shaft 18 passes externally of the engine and may drive a fuel supply control system pump. The shaft 11 surrounds an L.P. compressor and turbine shaft 10.
