Worm and worm screw reducer is with input and output shaft arranged in a staggered intersection way, is divided into cylindrical worm drive and torus worm drive according to the worm forms. It is applicable for the working case where the input shaft speed is not greater than 1500rpm, worm gear peripheral speed is not greater than 10m/s. It features compact structure, small size, stable operation, reliable use, low noise, large overload capacity, small moment of inertia, low transmission efficiency, low revolving speed. The worm is made of alloy steel and the worm gear of anti-friction material (bronze or gray iron). It is widely used in drive devices of metallurgy, mining, petroleum, chemical, printing and dyeing, food and other industries.
