Harmonic Drive
Worm Gear & RV Drive
It consists of a flex spline and a circular spline matching a dedicated tooth geometry.
We provide custom designed solutions for applications where high torque
and precision are critical

WORM
Main characteristics
| High speed deceleration rate | Decrease rate of 1/30-1/320 on inline input/output axis (1st stage) |
| Small and light |
As a result of comparing 1/3 volume and 1/2 weight of conventional reduction gear drive, torque capacity and reduction ratio are similar Outer diameter, 20-330mm |
| Simple mechanical structure | Consists of F/S, C/S, W/G |
| Consists of F/S, C/S, W/G |
High contact ratio (at least 3096 teeth meshing simultaneously), therefore high torque capacity Can provide 0.5 to 9,000 Nm |
| High efficiency | 80% or more |
| Excellent NVH characteristics | Low noise and vibration Very stable |
| Almost zero backlash | Precise motion control possible |
| High precision | Positioning precision, 1.5 arc minutes Repeatability. +/- 6 arc seconds |
