ACTUATING MECHANISM CAPABLE OF REALIZING DIFFERENT COMPRESSION RATIOS OF ROTOR ENGINE

摘要

An actuating mechanism capable of realizing different compression ratios of a rotor engine, comprising an eccentric shaft portion (1), a triangle rotor portion (2), and a control system; the eccentric shaft portion (1) comprises an eccentric shaft front portion (9), an electric three-jaw assembly (12) and an eccentric shaft rear portion (14); the triangle rotor portion (2) comprises a variable-capacitance actuating mechanism, a rotor front portion (4) and a rotor rear portion (6); the control system comprises a three-jaw electrically controlled system (18) and a rotary joint (16); an electric three-jaw (11) is controlled by means of the three-jaw electrically controlled system (18); the eccentric shaft portion (1) penetrates through the triangle rotor portion (2) so that the electric three-jaw assembly (12) is disposed in an annular groove; and the top of the electric three-jaw (11) stretches to make the variable-capacitance actuating mechanism do a reciprocating motion. The actuating mechanism can adjust the compression ratio of an engine by means of the entire compression ratio adjusting system, so that the rotor engine can work in an optimal compression ration under any working conditions, and the performance of the rotor engine itself can be further improved.
