    • A subject of the present invention is to prevent the reduction of rigidity caused by the increased length of a steam turbine rotor blade (100) and the degradation of vibration characteristics. A steam turbine rotor blade (100) according to the present invention comprises a profile (1) and a cover (2) integrally formed on and at an end of the profile (1), the leading edge of the cover (2) formed on the profile and the trailing edge of a cover (2) formed on an adjacent preceding profile (1) being in contact and connected with each other by the torsional return force (7) produced during rotation, and wherein the cover (2) formed on the profile (1) is provided with a radially-formed stepped portion (20) at the trailing edge, the stepped portion (20) having a height larger than the thickness of the cover (2).
    • 本发明的课题在于防止由于汽轮机动叶片100的长度变长而引起的刚性的降低和振动特性的降低。 根据本发明的蒸汽涡轮机转子叶片(100)包括型材(1)和在型材(1)的端部一体形成的盖(2),盖(2)的前缘形成在 在相邻的在前型材(1)上形成的盖(2)的轮廓和后缘通过在旋转过程中产生的扭转回复力(7)彼此接触和连接,并且其中盖(2)形成在 所述型材(1)在所述后缘处设置有径向形成的台阶部分(20),所述台阶部分(20)的高度大于所述盖子(2)的厚度。
