Retaining arrangement for rotor blades of axial-flow turbomachinery |
摘要 |
This invention relate to a retaining arrangement for rotor blades of axial-flow turbomachinery which features blade roots slots on a rotor disk for the accommodation and radial fixation of roter blades and which further features a continues, circumferential retaining ring for the axial fixation of the rotor blades in the blade root slots and a locking arrangement for the axial retention of the retaining ring. The retaining arrangement is characterized in that the retaining ring has recesses which correspond with sections of the blade root slots and projecting sections on its outer circumference. The present invention provides a cost-effective retaining arrangements for blade of axial-flow turbomachinery which provides for better control of the leakage flows in the blade root area, generally improved flow conditions in the inter-stage area, lower centrifugal forces and ease of assembly. The separation of the retaining function from the sealing function according to the present invention provide for a considerable saving in mass
