摘要： A rotor blade for a flow machine, in particular a steam turbine, includes an insertion root with a first finger and two second fingers which are arranged on either side of the first finger in axial direction. The first finger and the second fingers have a shoulder in axial direction on axial sides facing one another such that the fingers have a radially outer first portion and a radially inner second portion whose axial extension is shorter than that of the outer, first portion. In relation to a total axial width between axial sides of the two second fingers which face away from one another, the radial height of the first, radially outer portion is in the range of 0.39 to 0.45, particularly 0.40 to 0.44, and the radial height of the second, radially inner portion is between 0.40 and 0.46, particularly between 0.41 and 0.45.
摘要翻译：用于流动机械，特别是蒸汽涡轮机的转子叶片包括具有第一手指的插入根和布置在第一手指的轴向两侧的两个第二指状物。第一指状物和第二指状物在轴向上具有轴向方向上的肩部，所述轴向侧面彼此相对，使得指状物具有径向外部第一部分和径向内部第二部分，其轴向延伸短于外部第一部分的轴向延伸部。相对于彼此远离的两个第二指状物的轴向侧面之间的总轴向宽度，第一径向外部的径向高度在0.39至0.45的范围内，特别是0.40至0.44，径向高度的第二径向内部分在0.40和0.46之间，特别是在0.41和0.45之间。
