Abstract: An improvement of a worm gear reducer is provided where 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.

Abstract translation: 提供了一种蜗轮减速器的改进，其中输出齿轮由螺纹链代替，该螺纹链包括安装在两个环形平行链的延伸杆上的螺母状螺纹体，因此驱动螺杆和 螺纹链比蜗轮减速机的接触表面大得多，因此负载能力和耐磨性要高得多。 螺杆将驱动力施加在螺纹链的接触表面的质心处。 根据驱动螺杆的类型可以是辊，球或平移平头螺杆的三个实施例。 在滚子或滚珠丝杠上存在滚动接触，因此本发明的效率高于蜗轮减速器的效率，这允许其用作放大器。
