Worm gear mechanisms are often used to transmit motion and power between two interleaved shafts. The gear reduction ratio of worm gears is generally 20:1, and sometimes even as high as 300:1 or greater. Worm gears have following characteristics:
- A large transmission ratio can be obtained, which is more compact than a cross-shaft helical gear mechanism.
- The meshing tooth surfaces of a worm gear and a worm are in line contact. Its load-bearing capacity is much higher than that of a cross-axis helical gear mechanism
- A worm drive is equivalent to a spiral drive, which is multi-tooth meshing transmission. The transmission is stable and the noise is small.
- A worm gear mechanism is self-locking, which can realize reverse self-locking, that is, only a worm can drive a worm wheel, and the worm cannot be driven by the worm wheel.
- The transmission efficiency is low and the wear is serious.
- The axial force along worm is large.

Rakendused
Worm gear mechanisms are often used in situations where two shafts are interleaved, the transmission ratio is large, the transmission power is not large, or the operation is intermittent. Typical application of worm gear in mechanical transmission system includes speed reducers, cranes, winches, etc.
konkurentsieelise
- capability of customization of worm gear from drawings, 3D models, or simple part.
- capability of non-standard worm gear manufacturing.
- tootmisprotsessi terviklikkus, sealhulgas materjali valimine, sepistamine, peenetöötlus, lihvimine, kuumtöötlus ja pinnatöötlus jne.
