STEAM TURBINE WITH IMPROVED AXIAL FORCE PROPERTY

摘要

The present invention relates to a steam turbine which may reduce the load of a bearing element supporting a turbine shaft which transmits rotational drive force of a plurality of nozzle rotation bodies connected in multi-stages, the steam turbine comprising: a housing (110); a turbine shaft (120) which is pivotably supported by a bearing (121) in the housing; and a plurality of disk-shaped nozzle rotation bodies (130), combined integrally with the turbine shaft (120), which have at least one nozzle hole (131) formed therein and are stacked along the axial direction of the turbine shaft (120) so as to be rotated while a hydraulic fluid is sprayed, wherein the nozzle hole (131) has an inclination (θ) in the axial direction (c) of the turbine shaft (120) with respect to the normal direction (n) of the outer peripheral surface of the nozzle rotation bodies (130).
