摘要 |
<p>The buckets (2) on their rear side (6) are supported in a tangential direction by a support shoulder (7) of the wheel disc, which in a radial direction projects outwards by a dimension ''a'' wider than the nave-side edge of the bucket, in order to pick up the forces engaging the buckets from a nozzle jet. The buckets with their feet (3) can be moved in a radial direction into the wheel disc (1). With the radial inward movement of the buckets additionally a pivoting ina plane crossways to the wheel axis is necessary. The buckets can be made of a material with low specific weight in comparison to steel, e.g. of plastic or a light metal alloy. They can be made of a fibre-reinforced plastic or one which is fabric-reinforced.</p> |
