MECHANICAL FASTENING SYSTEM FOR ROTATING OR STATIONARY COMPONENTS

摘要

Mechanical fastening system (10) for rotating or stationary components (1) such as turbine or compressor blades on a rotor or a shaft or a casing, respectively comprising a circumferential mounting groove adapted for receiving root sections (2) of said rotating or stationary components (1) as well as intermediate fastening components (3) for fixation of said components (1) in equidistance positions, whereby said intermediate fastening components (3) comprise at least an upper platform (31) and at least a side plate (32) having a groove (4) for mounting on said rotor, whereby said intermediate fastening components (3) are made of a plurality of distinct parts (31, 32, 33) of different materials from which at least one clamping part (33) is made of or comprises a shape memory alloy or similar material having a pseudo-elasticity behavior.
