  • Tooth has a trapezoidal shape. Reference for tooth geometry is US Patent No 2,906,143.
  • Three gear profiles will be downloaded in DXF format.
    • Flex Spline (a.k.a Strain Gear): The deformable gear in the harmonic drive that transfers torque. It elastically deforms to mesh with the Circular Spline.
    • Circular Spline (a.k.a Ring Gear Profile): Typically fixed in place, meshes externally with the Flex Spline.
    • Output Gear: Used in pancake-style harmonic drives. It is the same tooth count as the Flex Spline but uses different module, allowing proper meshing in the Flex Spline's deformed position. Serves as the drive's output component.
