Single Start Worm

Single Start Worm

A worm can have one start or multiple starts to the thread. In single start worm screws, the worm wheel will only advance one tooth for every full rotation of the worm screw. 

A worm gear is a thread cut into a round bar, and a worm wheel is a gear that meshes with the worm at a shaft angle of 90 degrees. The set of a worm and worm wheel is called a worm gear.

Single Start Thread

A single helical thread formed around a screw body. For each 360° revolution of the screw, the form has advanced axially by the pitch of one thread. This has the same value as the pitch. In the case of a single start thread, lead and pitch are equal.

Double Start Thread

Two thread forms. During 360° revolution the forms advance axially by the combined pitch of two threads. Lead is 2x the pitch.

Triple Start Thread

Three thread forms. During 360° revolution the forms advance axially by the combined pitch of three threads. Lead is 3x the pitch.

Worm Drive

A worm drive consist of a worm wheel and worm gear also known as worm screw or just worm. The worm wheel is similar in appearance to a spur gear the worm gear is in the form of a screw generally with a flank angle of 20°. The worm gear screw can be single start or have multiple starts depending on the reduction ratio of the gear set. The worm has a relatively small number of threads on a small diameter and the worm wheel a large number of teeth on a large diameter. This combination offers a wide range of gear ratios typically from 4:1 to 300:1.

Worm Gear Set

double enveloping worm

We offer many types of worm gears and worms

01

Features

Large transmission ratios can be obtained, which are more compact than staggered-axis helical gear mechanisms

02

Features

The meshing tooth surfaces of the two wheels are in line contact, and its bearing capacity is much higher than that of the staggered shaft helical gear mechanism

03

Features

The worm drive is equivalent to a screw drive, which is a multi-tooth meshing drive, so the drive is stable and the noise is small.
