Turbomachine shaft damper device

摘要

The shaft (40) has a cylindrical wall with an inner surface portion and a member for attachment to a rotor disk of a turbo-machine at one end. The inner surface portion is attached to a vibration-damping laminate (30). The laminate has a layer (32) of visco-elastic material in contact with inner surface portion and a counter-layer (34) of rigid material comprising a lateral extension forming an attachment member (45) for mechanical attachment to the shaft and pressing the visco-elastic layer against the inner surface portion.
