Abstract
The invention concerns a Pelton turbine wheel comprising a rim (1) and several buckets (2) distributed at the rim periphery, characterised in that it comprises at least a ring-shaped flange (5, 6) integral with the rim and provided with housings (7) for receiving the buckets. The flange is capable of absorbing at least part of the efforts transmitted by the buckets (2) to the rim (1) and forms a peripheral strip (9) at external radial zones of the housings (7). The transmission of the efforts from the buckets (2) to the wheel rim (2) is carried out without generating too considerable a concentration zone of mechanical stresses.
