Între them, modulus m and pressure angle refer to the modulus and pressure angle of worm shaft surface, that is, the modulus and pressure angle of worm gear end face, which are standard values. 

The worm diametru coeficient q is the ratio of the worm indexing circle diameter to its modulus M.

Worm gear sets transmission is equivalent to spiral transmission, which is a multi tooth meshing transmission. Prin urmare, it is stabil in transmission, low in noise and self-locking.

Când the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the mechanism is self-locking and can achieve reverse self-locking, that is, only the worm can drive the worm, but not the worm.

Când viermele angrenajul seturile sunt cuplate, the relativ sliding speed între the meshing gear teeth is large, so the friction loss is large and the efficiency is low.

The axial force of worm is large.

Worm gear and worm mechanism is often used in situations where two shafts are staggered, transmission ratio is large, transmission power is not large or intermittent work.
