SECURING SEGMENT FOR THE VIBRATION DAMPING OF TURBINE BLADES AND ROTOR DEVICE
First Claim
1. A retaining segment for axially securing at least one rotor blade on a disk wheel of a rotor device of a jet engine that is operatively connectable to at least one rotor blade and to a disk wheel, wherein a first peripheral area of the retaining segment that is laterally disposed in the circumferential direction in the installed state, a projecting region is provided, and that in a second lateral peripheral area facing away from the first peripheral area, a receiving region is provided, with the projecting region of the retaining segment in the installed state being designed for at least partially overlapping a receiving region of a retaining segment that is identical in design and arranged adjacently in the circumferential direction, and for performing frictional work with said receiving region.

Abstract
A retaining segment for axially securing at least one rotor blade on a disk wheel of a rotor device of a jet engine is operatively connectable to at least one rotor blade and to a disk wheel. In a first peripheral area of the retaining segment that is laterally disposed in the circumferential direction in the installed state, a projecting region is provided, and in a second lateral peripheral area facing away from the first peripheral area, a receiving region is provided. The projecting region at least partially overlaps a receiving region of a retaining segment that is identical in design and arranged adjacently in the circumferential direction, and for performing frictional work with the receiving region. A rotor device has rotor blades arranged via blade roots substantially in the axial direction inside recesses of a disk wheel and secured by several such retaining segments.
