Descripción o resúmen

ABSTRACT

This invention is an improvement of a worm gear reducer, the output gear is substituted by a threaded chain, which is comprised of nut-like threaded bodies mounted on the extended rods of two endless parallel chains, thus the contact surfaces of the driving screw and the threaded chain is much greater than the contact surfaces of the worm gear reducer, and thus the load capacity and wear resistance are much higher. The screw applies the driving force at the centroid of the contact surface of the threaded chain. There are three embodiments depending of the type of the driving screw which may be either roller, ball or a plain translation screw. With the roller or the ball screws there is rolling contact and thus the efficiency of the present invention is higher than that of the worm gear reducer, which permits it to be used as an amplifier.
