About


Double enveloping worm gear set mounted with axes at a 90 degree angle. This type of gearing is also called Globoidal worm gearing, but the term double enveloping is more commonly used worldwide recently.

Large Loading Capacity
- There are more teeth in continuous meshing
- There are two instantaneous lines of contact, so the length of contact line is longer
- Under the same specification, compact dimension can be designed under the same transmitted power and the same transmission ratio

High Transmission Efficiency
- Easily establishing lubrication oil film
- Smaller friction coefficient
- Smoother functioning
- Lower noisiness
- Longer service life
- Saving energy

Grindablity
- Worm tooth can be ground
- Tooth surface hardness is higher ( HRC≥55 )
- Tooth surface roughness is lower ( Ra≤0.8 )
- Tooth accuracy grade is higher

APPLICATION
- Robot joints
- UGV
- Power wheelchairs
- Elderly scooters
- Scooters for disabled people
- Electric windows and doors
- Medical instruments
- Booster pump used on cars
- Car pedals
- Wind turbine tower hoists
- Power tools for food machinery industry
- Radar antennas
- Screw-down mechabism

In 1971, China successfully developed the planar double enveloping worm gear product. In 1981, China successfully manufactured a planar double enveloping worm gearing for screwdown gear of heavy mill, with a center distance of 1,200mm.
