Abstract

807,186. Mounting turbine and compressor blades. GENERAL MOTORS CORPORATION. April 18, 1957 [July 19, 1956], No. 12712/57. Class 110 (3). [Also in Group XXV] In a turbine or compressor wheel in which blades are mounted by their roots in undercut slots extending axially across the rotor rim, means are provided to prevent endwise movement of the blades in the slots. Each blademounting slot 17 has in its base a socket 23 and each blade root 14 is formed with a transverse socket 24, also with a cut-away portion 28. Locking pins 21 are provided having a plate portion 26 secured thereto, the plate portion having a deformable tab 31 at the free end. The pin 21 is first inserted into the socket 23 at the base of the blade-mounting slot, the plate portion 26 lying on the bottom of the slot. The blade root is then inserted into the slot from the right, Fig. 2, the cut-away portion 28 passing over the projecting end of the pin 21 and the plate portion 26. The pin 21 is then moved radially outwardly by means of the plate portion 26 so that the outer end of the pin engages in the transverse slot 24 in the blade root, the plate portion 26 lying against the cut-away portion 28 of the blade root. The locking pin is held in this radially outward position by means of a rectangular support plate 32 disposed between the plate portion 26 and the bottom of the blade-mounting slot, the tab 31 of the plate portion being finally peened over so as to secure the support plate in position. Alternatively, the clearance necessary to permit assembly may be provided in the socket 24 in the blade root so that the pin would have to be moved radially inwardly into the socket at the base of the blade-mounting slot after assembly, the support plate in this case being disposed between the plate portion 26 and the blade root.
