Introduction and Advantages

Worm (or worm gear) and Wormgear (or worm wheel) transfer power 90 degree and can have relatively large range of gear ratio so they have been used in many industries for centuries. But in general, wormgears are also known for their bad efficiencies, noises and frequent maintenance.
Unlike cylindrical wormgear sets, Double Enveloping worm and gear are wrapping (“enveloping”) each other by optimization design technology so they have (1)much more teeth contacts, (2)much stronger, (3)much higher efficiency, (4)much lower NVH(Noise, Vibration, Harshness), and (5)much longer life.
