WORM

WORM

Worm is with only one or a few helical gears, and with worm gear meshing and

composition of the gear axis gear pair are. The dividing surface can be YuanZhuMian,

taper surface or ring surface.

We have the following types:

Common cylindrical worm transmission

Archimedes worm

Method to straight profile worm

Involute worm

Cone envelope cylindrical worm

The worm choice broken down

Choose worm z1 broken down,

the main consideration ratio, efficiency and manufacture three aspects

From manufacturing, the more broken down, worm manufacturing precision

 and the higher requirements

From improve efficiency look, the more broken down, efficiency is higher; If you

want to lock itself, should choose single head

From improve transmission ratio, should choose the less broken down;

In power transmission, in considering compact structure, under the premise of

should be very good to consider raising efficiency. When I drive more hours,

appropriate USES more worm. And in the transport of motion demand since the

lock, often choose single head worm.
