Definitions
- the stop means here consists of two plates 39, 40 having a T-shaped contour, mounted on either side of the circumferential groove in the sector 17.
- the vertical bar of each T forms a tooth, such that 41 and 42, the width of which is equal to the distance between the stilts of two neighboring blades.
- the thickness of these plates is such that it occupies the space limited by the underside of the platforms and the upper surface of the rim forming the bottom of the sector 17.
- Each tooth 41, 42 has a threaded hole, respectively 28 ', 29' receiving screws 30, 31 held in half-holes 34, 35 and 36, 37 ( Figure 7) of the side edges of two contiguous platforms, respectively 19, 20 and 20, 18.
- the device for mounting and fixing blades, object of the invention eliminates a cause of fatigue of the turbine rotor or of the compressor without requiring an increase in weight or difficulty in machining.
