| 20100180703 | RECIPROCATING AND ROTATING TYPE POWER TRANSFORMING APPARATUS - Provided is a reciprocating rotary power transforming apparatus that can simplify its structure, reduce loss of friction energy occurring from motion transformation, and perform transformation between a reciprocating rotary motion and a uni-directional rotary motion. The reciprocating rotary power transforming apparatus includes a reciprocating rotary axis performing a reciprocating rotary motion, a uni-directional rotary axis performing a unidirectional rotary motion, a housing being disposed so that the reciprocating rotary axis and the uni-directional rotary axis may be orthogonal to each other on the same plane and being supported to un-restrict its rotation, and a motion transforming unit being connected to the reciprocating rotary axis and being constructed to perform transformation between the reciprocating rotary motion and the uni-directional rotary motion by a conical rotary motion and a twisting motion when power is transferred to the reciprocating rotary axis or to the uni-directional rotary axis. | 07-22-2010 |
