Specification

Advantages

1. Zero backlash transmission
Unique elastic meshing principle achieves ultra-high precision of <20 arc minutes, far exceeding planetary/cycloid reducers
2. Ultra-high torque density
Single-stage reduction ratio can reach 50:1~320:1, 30-50% lighter than planetary gears at the same torque
3. Compact hollow design
Minimum axial length is only 1.5 times the outer diameter, and the center through hole supports cable/fluid circuit integration
4. Ultra-long service life
Using carburized alloy steel flexible wheel + IH tooth shape optimization, the service life can reach 15,000 hours+
5. Multi-environment adaptability
Operating temperature range -40℃~+120℃ (aerospace-grade models reach -200℃~+150℃)
