Abstract

PURPOSE: To prolong the service life of a belt by a method wherein two or more pulleys are provided on the same shaft and a belt consisting of a shape memory alloy element is wound alternately around two sets of the pulleys.
CONSTITUTION: Pulleys 17, 18 having smaller diameters are provided coaxially with pulleys 15, 16 respectively, and the belt 19 consiting of the shape memory alloy element is wound alternately around the two sets of the pulleys, in the order of the pulley 15, the pulley 16, the pulley 17 and the pulley 18. Accordingly, the belt 19 travels two times around the engine during when it performs a complete cycle of traveling, and the length of the belt is about two times of that of a conventional belt. Therefore, for the same number of revolution, the number of heating-cooling cycles repeated is reduced to about 1/2 of the corresponding number of the conventional, and the service life of the belt 19 can be prolonged.
