The invention concerns a turbine shaft having stepped bearings on which ds are shrunk on. It is characterized in that the connecting surface between two successive bearings consists of two conical portions separated by a cylindrical portion and toroidal connecting portions between the cylindrical portion and the conical portions. The invention reduces the concentrations of stresses and applies more particularly to elastic fluid turbine shafts.

Turbine shaft having inserted disks

A fixing arrangement for a guide part of a fixed casing on a rotating mace whose rotor is supported by a concrete beam, is characterized in that the guide part is fixed to a plate applied against a lateral wall of the beam and is integral with trusses sunk in the mass of the beam. The invention applies, more particularly, to steam turbine exhaust chambers.
