Abstract
599,698. Turbine blades. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. March 2, 1945, No. 5229. Convention date, March 2, 1944. [Class 110 (iii)] In a blade ring for a radial flow turbine of the kind in which axially extending blades 24, Fig. 5, are secured to a carrying ring 28 by projections extending from the blade roots and interlocked with both the radially inner and outer edges of the carrying ring, that face of each blade root adjacent the carrying ring is cut away to provide two radially spaced projections 44, 48, each positively locked to the carrying ring against bending stresses, the recess between the projections receiving a projecting portion 40 of the carrying ring. The projection 44 is serrated or threaded, but may instead be identical with the dovetail projection 48. The sides 42 of the carrying ring may be outwardly bent prior to insertion of the blades and subsequently rolled in. The blade roots may be welded together. The projections may each be in the form of a halfdovelail 34, Fig. 6. The inner projection 50 may be threaded in the case where the radial depth of the blade is so much less than that of the carrying ring that a rolling operation cannot be applied.
