Abstract
Official abstract text for this publication.
A damper ( 2 ) for damping a blade movement of a turbomachine ( 1 ), and to a method for producing the damper ( 2 ). The damper ( 2 ) has at least one side surface ( 21, 21 ′) which can be brought into frictional contact with a friction surface of the turbomachine ( 1 ) in order to damp a blade movement. The side surfaces ( 21, 21 ′) are asymmetrically convex in shape.
First claim
Opening claim text (preview).
What is claimed is: 1. A damper for damping a blade movement of a turbomachine, the damper comprising: a single piece body having a polygonal shape in a cross section normal to a rotor axis of the turbomachine, wherein the single piece body includes a first side surface intended to damp the blade movement by frictional contact with a friction surface of a first blade of the turbomachine, the first side surface being asymmetrically convex in shape, the asymmetrically convex first…
