| 摘要 |
The present invention relates to a counter/contra-rotating device for fluid machinery, which converts energy from the movement of fluid into mechanical energy. The counter/contra-rotating device for fluid machinery comprises: at least one first rotor having an inner contacting member formed on an inner periphery thereof, and a plurality of wings formed on an outer periphery thereof that rotate in a first direction in accordance with the flow of fluid; at least one second rotor having an inner contacting member formed on an inner periphery thereof, having a plurality of wings installed on an outer periphery thereof that rotate in a second direction opposite the first direction in accordance with the flow of fluid, and arranged coaxially and alternately with the first rotor; a plurality of drive units radially arranged about an axis of the first rotor, for receiving rotation from the inner contacting member of the first rotor; a plurality of reversing units radially arranged about an axis of the second rotor between the plurality of drive units, for reversing the rotation of the plurality of drive units and relaying the rotation to the inner contacting member of the second rotor; and an output unit for outputting the rotational force of the first rotor and second rotor. |
