Drive belt variable speed system for thermal engine comprises conical side plates on shaft with counterweights moving belt between lower and upper position relative to shaft.

摘要

The belt drive system has a motor shaft (11) and two conical side plates (4,5). Counterweights (3) are provided to change the position of the side plate (4) as a function of the rotational speed, as well as to position the drive belt (15) from a lower position close to the shaft, to a higher position close to the edges of the side plates. The conical surface of each cone is formed at an angle of 13 degrees and the point of each cone has an identical flat surface formed on it.
