Hydroelectric turbine with floating rotor |
| 摘要 |
The present invention is concerned with a hydroelectric turbine which includes a stator and a shaftless rotor housed for rotation within the stator, the stator defining an opening or channel in which the rotor is retained and which channel is dimension to permit the rotor to undergo both axial rotation and displacement along the circumference of the opening, whereby during operation the rotor assumes substantially hypocycloidal motion relative to the stator. |

1. A hydroelectric turbine comprising a stator and a shaftless rotor, the stator defining an opening in which the rotor is housed for rotation; a set of bearings supporting the rotor within the stator, the bearings comprising an array of bearing units on one or the other of the stator and rotor and a corresponding journal on the other of the stator and rotor; wherein the opening is shaped and dimensioned such that the journal only contacts a small arc of the bearing units at any one time to permit the rotor to undergo rotation about a central axis of the rotor and displacement along the circumference of the opening in a direction opposite to that in which the rotor is rotating.
