VIBRATION DAMPER FOR ROTARY BLADE OF TURBINE

摘要

Device for damping the vibrations of moving blades of turbine, in which the blade roots are engages in the alveolus distributed over the periphery of a disk on which is anchored, on the rim that - latter, a front flange formed of sectors, and a rear flange constitutes a single annular piece against which bear the blade roots and the teeth of the disk. / p & & p & between the root 4 of the blade 2 and the bottom 3a of the alveole 3 of the disk 1, is willing, behind the front flange 5, a wedge 12 in the form of a wedge which, under the action of centrifugal force, exerted on the blade 2 a force causing it to slide that - latter axially so that it comes into thrust against the flange 9 of the back. / p & & p & the invention is used for damping the vibrations of rotary turbine blades.
