Abstract
622,626. Turbine blades and rotors. ARMSTRONG SIDDELEY MOTORS, Ltd., and CLARK, T. April 2, 1947, No. 8920. [Class 110(iii)] A bladed turbine disc is built up of axially-spaced portions 11, 13, Fig. 1, between which the blades 18 are held by the engagement of toothed roots 16 of the blades with corresponding teeth or the like on the adjacent faces of the rims of the disc portions, and binding rings 24 are held by parts of the blades against the axiallyouter faces of the rims to prevent the rims from separating from one another. The teeth 15 are preferably of buttress form, as shown, and there may be but a single tooth on each side of each blade root. One disc portion 13 is secured upon a hub 12 of the other disc portion 11 by a nut 17. The binding rings may be in the form of split rings which are sprung into place within flanges 20 formed on all or some of the blade shrouds 19, and may be located by peening into grooves on the disc portions, as at 25. The shrouds 19, which may abut one another in the circumferential direction, may be of rectangular or parallelogrammic form. In a modification, the binding rings are of unsplit form and are assembled by either or both shrinking the rings and heating the disc. In a further modification, Fig. 3, each binding ring is a continuous ring with castellations 28 on its outer periphery. The flanges 20 on alternate blades are omitted, and each binding ring is assembled by passing the castellations through the spaces 29 between successive flanges 20 and then turning the ring into the position shown. Angular movement of the ring can be prevented by attaching it to the flanges 19 by welding, peening or the use of dowels.
