Worm drive
Worm drive refers to the main action of the worm deceleration drive, when the anti-travel is not self-locking, it can also be worm wheel-based action to increase the speed drive. Transmission power should generally be below 50kW (maximum up to 1000kW or so), the relative sliding speed between the tooth surfaces should be in the Below 15m/s (up to 35m/s).
Worm drive consists of worm and worm wheel, general worm for the active part. The worm and threads are the same as the right-hand and left-hand points, respectively, known as a right-hand and left-hand worm.

1.Large transmission ratio, compact structure. The worm head number with Z1 said (general Z1 = 1 ~ 4), the number of worm gear teeth with Z2 said. From the ratio formula I = Z2/Z1 can be seen, when Z1 = 1, that is, the worm for a single head, the worm shall turn Z2 worm wheel before Turn a turn, so you can get a large transmission ratio, generally in the power transmission, take the transmission ratio I = 10-80; in the indexing mechanism. Such a large transmission, for example with gears, requires a multi-stage drive, so worm drives, for example, can be up to 1000. Compact structure, small size, and lightweight.
2.Smooth transmission, no noise. Because the worm gear teeth are continuous uninterrupted helical teeth, it meshes with the worm gear teeth continuously, the worm gear teeth do not enter and exit the meshing of the process, so it works smoothly with less shock, vibration, and noise.
3.With self-locking. The spiral angle of the worm is very small, the worm can only drive the worm drive, and the worm wheel can not drive the worm rotation.
4. Worm drive efficiency is low, the general view of the worm drive efficiency than gear drive low. Especially with self-locking worm drive, its efficiency at 0.5 below, general efficiency only 0.7 ~ 0.9.
5. Heat generation, the tooth surface is easy to wear, high cost.
