Abstract

1500575 Balancing means for axial-flow turbines and compressors GENERAL ELECTRIC CO 3 April 1975 [23 May 1974] 13710/75 Headings F1C and F1T A turbomachine comprises a rotor rim 12, Fig. 1 with dovetailed axial grooves 18 for retaining blade roots 30, and balance weights 56 having opposed tang members 70, 72, Fig. 5, which are received in radial grooves 52, 54 and retained by a snap ring 78 inserted between a side face 14 of the rotor rim 12 and integral hook portions 44 thereof. Each blade has a platform 32 between root 30 and airfoil 28, the platforms preventing outward movement of the balance weights during centrifugal loading. Each weight has a notch 76, Fig. 4, for engagement with snap ring 78. The weights can be withdrawn and replaced after removal of the snap ring which together with a second snap ring 82 serves also to retain the blades in their respective axial grooves.
