    摘要: A turbo machine (1, 101), in particular turbine or compressor, includes a rotor (2, 102) which has at least one moving blade row (4, 104) with a plurality of moving blades (5, 105), and a stator (3) which has at least one guide vane row (6, 106) with a plurality of guide vanes (7, 107), at least one moving blade row (4, 104) having a shroud (8, 108). The shroud (8, 108) is designed to be self-supporting in such a way that it can at least partially absorb the centrifugal forces arising during operation and discharge them in the circumferential direction.

    摘要: 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.
