METHOD OF MANUFATURING BLADED RINGS FOR RADIAL TURBOMACHINES USING STOP ELEMENTS WITH LOCALISED WELDS; CORRESPONDING BLADED RING

摘要

A kind of radial direction (9) of blade ring the present invention relates to manufacture for turbine, comprising steps of assembling the first support ring (15) and the second support ring (22), with multiple blades (27), with the first connection ring (40) and the second connection ring (41), to make to fill vaned ring (9), it includes first, second and second support ring (15, 22) coaxial and axially spaced from one another, with in multiple blades (27) equidistant placement (from central axis X-X) and be inserted in above-mentioned first and second support ring (15, 22). The first connection ring (40) that this method further includes steadily each blade (27) of engagement first end (30) steadily engages the second end (27) of each blade (31) to the second connection ring (41), fixes the first connection ring (40) and the first support ring (15) and fixes the second connection ring (41) and the second support ring (22). First support ring (15), second support ring (22), multiple blades (27), the first connection ring (40), second connection ring (41) all finish element is before assembly, it means that during the final geometry that them are presented in they does not need further processing and/or plastic deformation with them and/or after assembling.
