Abstract

1339100 Turbine blade fixing WESTING- HOUSE ELECTRIC CORP 25 Aug 1972 [5 Oct 1971] 39789/72 Heading FIT Steam turbine blades 1 are secured to rotor 3 by double lobed pins 11 engaging in axial slots 7', 9 in blade bases 5 and rotor 3 respectively. In a modification Figs. 4 and 5, (not shown), the abutting edges (13') of the blade bases (5') are curved to the shape of the blade camber line so that the pins 11 extend through two adjacent bases. Each pin 11 may be formed by a number of axial lengths (11'), Fig. 2, (not shown).
