PROBLEM TO BE SOLVED: To develop a motor with power-saving function, low pollution and high output, develop a reciprocating piston with high efficiency, and enable running of a bicycle stabler than conventional one even under high resistance. SOLUTION: In a planetary moving device housed in an arm of a crank, an inter mediate gear between a sun gear 1 and a planetary gear 2 of James Watt. The intermediate gear may be replaced with a chain gear (or timing pulley) to equalize rotational speed and direction of the sun and planetary gears, or chain gears. A crank shaft is rotated once with one reciprocation of a piston. The motion of the piston is differentiated in advancing and returning motions. In advancing, the piston is decelerated for reducing a load applied thereto. Returning is carried out speedily for reducing loss. As a result, energy required for one reciprocation of the piston is reduced for saving energy and increasing an output. In order to transduce the rotational motion to reciprocating motion, the rotational speed of the crank is unchanged. Advancing motion of the piston is decelerated for improving effect of work, and returning is speedily carried out. |
