Abstract

27,654. Eyermann, W. H. Nov. 27. Blades.--The blades of a radial-flow turbine are made dovetailed in shape and are secured in corresponding grooves in the rotor or stator by hard metal keys or wedges. The space in the grooves below the blade-roots may be filled with a fluid, which, when the wedges are inserted, forces the blades outwards, as shown in Fig. 3. In place of a fluid, small springs may be used as shown in Fig. 5. In the latter construction, the wedge and the blade are bevelled at d, so that when the blade is pushed outwards into its normal position the wedge is locked. The wedge may be held by caulking the edge of the groove over it. The wedge may stand out from the stator or rotor so as to give support to the blade beyond the root.
