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