WORM GEAR PAIR

.WORM GEAR PAIR

RoHS Compliance

High reduction gear
Worm gear pair provide high speed reduction ration with only one gear pair in compact space compared with other types of gears. It consists of cylindrical worm gear and worm wheel. We offer maximum 100:1 ratio by only one worm gear pair. Another advantage is low noise level. Disadvantages are low efficiency and generation of heat.

Advantage of Worm Gears from KG – Cold rolling Worm Gears
1) The hardness of the helicoid surface has been manufacturered by work hardening because cold rolling was performed and the worms has more excellent mechanical properties than machined worms because the metallic fibrous structre has not been cut.

2) The surface hardness after cold rolling process was increased by 1.2 to 1.3 times compared with the hardness of original material, and the hardness of the helicoid surface was increased to HB240 to 260.

3) Cold rolling worm is suitable for the miniature module and can be rotated smoothly without damaging the worm wheel of the Acetal or other soft materials.

4) Due to this cold rolling method, the helicoid surface of KG-Worm (M0.5 to 2.0) has a mirror finishing that looks like a mirror. The KG-Precision Cold Rolling Worm is able to provide a smooth engagement and high durability.
