Axial securing device for rotor blades of axial turbo machines, consists of securing body with power-absorbent section and securing section with two holder elements

摘要

The rotor blades (10) are each secured via a blade foot (12) and a securing body (22) in a radial groove (14). The securing body has a power-absorbent section (24) and a securing section (32). A first holder element (26) of the securing body is formed by two noses on the body, a second holder element (28) is formed on the power-absorbent section. The noses are positively connected with the upstream directed blade carrier end face (36) respectively the downstream directed holder surface (40) of the blade foot.
