摘要

Mechanism of continuous variation of speed of the system of translation of the harvester machines, interspersed between the motor pulley and the motor of the change of speeds, which is characterized by the fact that on a tilting arm a set consisting of two plates is mounted on a common element of opposite conical faces and, between both, a third plate sliding axially on the common element, endowed with two opposite conical faces and similar to the previous ones, whose common element is mounted by means of bearings on a hollow shaft fixed to said swingarm, in shape able to regulate its position by means of a screw that passes through its interior, so that by tilting the arm a variation of the distances between the axis of the assembly to the axis of the motor pulley and to the axis of the motor is obtained, which determines when constant the lengths of the trapeze belts an axial displacement of the intermediate plate that results in an increase in the primitive diameter embraced by one of the belts and a decrease in the other belt, varying the speed ratio between the motor and the motor pulley.
