摘要： A rotating blade row is provided for the final stage of a steam turbine has blades with an integrated shroud. The shroud of each blade has a projection in the axial direction, in each case on its pressure side, which prevents droplets in the working fluid of the steam turbine from reaching the shroud fillet of the respective subsequent blade in the flow direction. The shroud fillet is therefore protected against erosion damage caused by droplets impact erosion. The projection is positioned and of such a size that mass equilibrium is ensured between the suction side and the pressure side of the shroud, and stress equilibrium is ensured between the projection on the pressure side and the suction-side shroud. The projection furthermore has a recess between its greatest axial extent and the leading edge.
摘要翻译：提供旋转刀片排用于蒸汽涡轮机的最后级具有具有集成护罩的刀片。每个叶片的护罩在轴向方向上具有突起，在每种情况下都具有在其压力侧上的突起，其防止蒸汽轮机的工作流体中的液滴在流动方向上到达相应后续叶片的护罩角。因此，护罩内底可以防止由液滴冲击侵蚀引起的侵蚀损坏。该突起的定位和尺寸使得在护罩的吸力侧和压力侧之间确保质量平衡，并且确保压力侧的突起与吸力侧护罩之间的应力平衡。突起还具有在其最大轴向范围和前缘之间的凹部。
