Abstract

906,476. Turbine and compressor blades. FAIRWEATHER, H. G. C. (Westinghouse Electric Corporation). Oct. 11, 1960, No. 34843/60. Class 110 (3). A turbine or compressor rotor comprises blades 11, a blade supporting member 10, having recesses 16 and arcuate grooves 23 in endwise communication therewith, blade-retaining means 14 having a groove 20, the grooves 20, 23 being open-ended and facing each other, and a spring member or clip 25 received in the grooves and locking the retaining means against axial movement, the spring member 25 being deflectable radially to permit insertion and removal from the grooves and having means co-operating with the retaining means 14 to lock the spring member 25 against longitudinal displacement in the grooves 20, 23. The ends 26 of the spring member 25 are the same width as the groove 23 and the width of the central portion 27 is reduced to that of the groove 20. Shoulders 28 on the spring members abut side faces 18 on the blade roots to provide locking means against longitudinal displacement. In one method of assembly the spring member 25 is placed in the groove 23 before the blade is inserted (Fig. 1), When the root portion contacts the member 25, the central portion 27 is deflected radially inwardly and when the grooves 20, 23 are in alignment, the clip is released. The blade may be removed by applying a suitable tool to either or both ends of the clip, thereby deflecting it clear of the groove 20. By varying the width of the clip if desired, a limited degree of axial movement of the blade is possible. Since the ends 26 of the clip are visible after assembly, inspection of the blade locking components is facilitated.
