POWER GENERATING SET WITH FIXED BLADED TYPE SOLID HEAT ENGINE UTILIZING SHAPE MEMORY MATERIAL

摘要

PURPOSE:To generate a large output with a simple structure by making a constitution wherein a plurality of engine speed converting parts with a shape memory material used are provided around a rotor having a plurality of blades and an energy converting function of the shape memory material is utilized to rotate the rotor. CONSTITUTION:A fly wheel 8 is coupled to an end via a rotation speed conversion unit 6 composed of gear arrays, a plurality of rotors 1 are fixed on a rotor shaft 4 driving a power generator 9 with the rotation, and a plurality of rollers 2 of a plurality of blades 3 extending along radial directions of the respective rotors 1 are pivoted respectively. Around each rotor 1, a plurality of automatic conversion mechanisms 11 composed of a plurality of driving elements 10 are provided. The driving element 10 is constituted of shape memory material elastic pieces 12, 13, a contact board 16 having sliding support points 14, 15 which are fittable to sliding ends of the pieces 12, 13, and a fixed board 19 having sliding support points 17, 18. A function of the elastic pieces 12, 13 which stretch due to blow of heat medium and cold heat medium is received by the blade 3 to have the rotor shaft 4 rotated.
