Hello everyone. In this video, we will take a detailed look at the worm mechanical transmission. Structure, classification, advantages and disadvantages. Materials and manufacturing methods, forces and parameters in engagement, interesting facts, areas of application. Worm gears refer to toothed and helical gears, which have characteristic features of toothed and helical gears. The worm gear transmits motion according to the principle of a screw pair, where the screw is a worm (as a rule, it is a screw with a trapezoidal cut), and the wheel is similar to a sector that was cut out of a long nut and bent in a circle. The engagement of a worm pair is similar to the engagement of a gear wheel (with teeth of a special shape) with a toothed rack. At the same time, the geometric axes of the shafts intersect at an angle of 90°. Video about gears: • Gears Official pages: https://www.facebook.com/profile.php?... / romaniv_2809 / mechanics_ukr
