Abstract
Improvements in speed variators of the type of two extendable pulleys with lateral gear chain, characterized by the fact that each extendable pulley is constituted by two conical plates that on the inside are reinforced by two conical jackets, of treated steel and of greater resistance, covering practically the entire work area and being provided with grooves or radial teeth that extend from the central part to the periphery with a width substantially equal to the width of the gaps, making the assembly of the jackets and plates of each pulley so that the teeth of one plate are facing each other and in correspondence with each other's teeth.
