1, worm drive can only forward drive reverse locked or its driving wheel and driven wheel are not interchangeable, but exist in the transmission process due to its structural characteristics of axial force transmission efficiency is low;
2, when the gear drive can is inverse transmission driving wheel and driven wheel interchangeable;
3, compared with gear transmission, the power transmission ratio between 8 ~ 100, the transmission ratio can reach 1000 in dividing mechanism;
Transmission is very smooth, noise is low;
4, under certain conditions can realize the advantages of self-locking and widely used, worm transmission efficiency is low, the calorific value and wear is very serious, worm gear ring part often use good antifriction performance non-ferrous metals (
Such as bronze)
