Abstract

881,690. Turbine blades. GENERAL MOTORS CORPORATION. July 6, 1960 [Aug. 7, 1959], No. 23617/60. Class 110 (3). [Also in Group XXV] A turbine rotor wheel 10 has blades 18 attached thereto by axial insertion of the blade roots 16 into undercut slots 14 in the rim 12, the blades being held against movement out of the slots by spring clips 28 lodged in respective recesses 22 in the rim, each clip having a resilient tongue 34 entering a notch 26 in a blade platform 35 and having a portion which is overhung by an adjoining blade platform. To assemble the rotor each clip 28 is disposed in a recess 22 and the clip tongue 34 is flexed into a space 37 between adjacent blade platforms allowing a blade to be axially moved into position until the notch 26 is aligned with the recess 22. The curved section 32 of the clip 28 is disposed below the overhanging platform 35 of the blade adjacent the one locked by the clip. In alternative constructions a clip may have two oppositely facing tongues 38, 40 (Fig. 6), to permit the locking of adjacent blades or the tongue 34 may be dispensed with and the section 32 extended and provided with an upstanding tongue. In the clip shown in Fig. 7, the tongue 42 engages in the notch 26 and is depressed radially for insertion or removal of the blade.
