Turbine shaft having inserted disks |
摘要 |
The invention concerns a turbine shaft having stepped bearings on which disks 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.
