.Point 1. “G”Gear Technique
A. Growth the life of flexspline by Tooth “R” angle growth avoiding large stress on root of gear
B. Eliminate interference in “G” gear meshing by finite element analysis of flexspline’s stress & deformation analysis by ANSYS
C. Improve rigidity of reducer by growth height of teeth appropriately
D. Output torque scope enlarged by more teeth meshing (from 35% to,43% up), which extends the life of flexspline too
Point 2. Wave Generator Shaped Oval Research
Finding accurate contour of shaped oval of wave generator by simulation
“G”gear meshing condition & flexspline stress and deformation when running;
Point 3. Unique Design In Flexspline Thickness
Improving flexspline strength & life performance by releasing the stress when running from the best thickness unique Design of flexspine.
Point 4. Lower Noise
With independent “G“ teeth & flexspline thickness unique design, the teeth have not any interference, which eliminates the noise by sympathetic vibration.
Point 5. Higher Design Freedom
Ratio: Design 30-200 Ratio has better performance than traditional theory
Low Inertia: All rotation parts can be designed by weight reduction, which will reduce the inertia of each rotation parts. Transmission efficiency will be improved by stable running/stop under this design.
Light Weight: Design weight of wave generator & circular spline can be lower 30%-40% than standard model, which can meet customized choice for more condition usage.
