    • A blade for a turbo machine has a blade section and a shroud element terminating the blade section in the blade section longitudinal direction. The blade section has a suction face and a pressure face. The shroud element extends essentially at right angles to the blade section longitudinal direction and has a first platform section projecting beyond the blade section and a second platform section projecting beyond the blade section. The platform sections are asymmetric with respect to one another. At least the first platform section of the shroud element is arranged at an additional inclination angle with respect to a normal alignment of the first platform section, with the additional inclination angle being in the opposite direction to the bending torque which acts on the first platform section during operation.
    • 用于涡轮机的叶片具有叶片部分和在叶片部分纵向方向上终止叶片部分的护罩元件。 叶片部分具有吸力面和压力面。 护罩元件基本上与叶片部分纵向方向成直角地延伸,并且具有突出超过叶片部分的第一平台部分和突出超过叶片部分的第二平台部分。 平台部分相对于彼此是不对称的。 护罩元件的至少第一平台部分相对于第一平台部分的正常对准以额外的倾斜角度布置,附加倾斜角度与作用在第一平台部分上的弯曲扭矩相反的方向 在运行期间。

    • A turbomachine (1), in particular a turbine or compressor, includes a rotor (2) which has at least one moving blade row (4) with a plurality of moving blades (5), and a stator (3) which has at least one guide vane row (6) with a plurality of guide vanes (7), at least in one of the blade or vane rows (4, 6) all the blades or vanes (5, 7) each having a shroud plate (10). In order to simplify the maintenance of the turbo-machine (1), the shroud plates (10) are separate components with respect to the respective blade or vane (5, 7) and are mounted on the respective blade or vane (5, 7), shroud plates (10) adjacent in the circumferential direction (9) being coupled to one another for the transmission of tensile forces in the circumferential direction (9).
    • 涡轮机(1),特别是涡轮机或压缩机,包括具有至少一个具有多个活动叶片(5)的至少一个活动叶片排(4)的转子(2)和至少具有至少 具有多个导向叶片(7)的一个导向叶片排(6),至少在叶片或叶片排(4,6)之一中,所有叶片或叶片(5,7)均具有护罩板(10) 。 为了简化涡轮机(1)的维护,护罩板(10)相对于相应的叶片或叶片(5,7)是分离的部件,并且安装在相应的叶片或叶片(5,7)上 ),沿圆周方向(9)相邻的护罩板(10)彼此联接以在周向(9)上传递张力。
