Embodiment Construction

[0029] Referring now to the drawings, there is shown a hydroelectric turbine generally indicated at 10 in accordance with a preferred embodiment of the present invention, adapted to provide improved operation by virtue of novel movements of its components during use. The turbine 10 includes a stator 12 , which in use is secured, for example, to the seabed, and a rotor 14 constrained to rotate within the stator 12 , as will be described in detail hereinafter.

[0030] like image 3 As shown, rotor 14 includes: a substantially circular inner rim 16 defining an open center; a substantially circular outer rim 18; However, it should be understood from the following description of the operation of the turbine 10 that the configuration and / or number of blades 20, and the provision of the inner rim 16 are not necessary for the operation of the invention and may be modified while maintaining the present invention. Invented function.

[0031] refer to figure 2 , in the preferred emb...

Abstract

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.

Description

technical field [0001] The invention relates to a hydroelectric turbine having a stator and a shaftless rotor accommodating the rotor for rotation within the stator and allowing a substantially hypocycloidal movement within the stator. Background technique [0002] The present invention relates generally to the field of turbines for generating electricity by harnessing the flow of water, and more particularly to devices in which the tidal flow of water results in the movement of a large impeller-type rotor having an annular outer rim disposed within a large annular casing. rotate. [0003] While most turbines are constructed with a central rotating shaft to which the blades or rotors are mounted, it is also known to manufacture open-centered turbines, also known as rimmed turbines. Turbines with open-center rotors in which blades are mounted between inner and outer annular bores or annular rims, and in which energy is transferred through the outer rim to the annular casing ...
