Summary:PURPOSE:To make a warning buzzer operate when a revolving speed exceeds the specified range as well as to find out the looseness of a belt as early as possible, by installing a tachometer which outputs such a voltage that is proportional to the revolving speed of a driven pulley, and comparing the voltage with the output voltage of a generator. CONSTITUTION:A belt transmission consists of a driving pulley 7, a driven pulley 8 and a transmission belt 9 all installed in an output shaft of an engine. In this driven pulley 8, there is provided with a tacho-generator 12 as a tachometer, converting a revolving speed of the pulley 8 into voltage and inputting it into a comparator 13. And, output of a charging generator 5 is also inputted into this comparator 13, and when the difference between them exceeds the specified range, a buzzer 14 is operated. In addition, at his time, if an operating mechanism 11 is operated, a hydraulic cylinder 11a operates, adjusting a degree of tension of the belt 9 automatically.
