VIBRATION DAMPING CONSTRUCTION OF MOVING BLADE

摘要

PURPOSE:To thin each part of a tie wire located between blades so as to reduce the centrifugal stress by sleeving said part of the tie wire which passes through a blade and welding the sleeve to the tie wire. CONSTITUTION:A sleeve 4 is fit to each part at which a tie wire 3 passes through a blade 1 and then welded to the tie wire 3. Thus, the tie wire 3 may gain larger thickness at only the part which passes through the blade.
