Abstract
The S-shaped flexible gear structure comprises a connecting bottom and a tooth-shaped area, the tooth-shaped area comprises a tooth part and a connecting part, the bottom end of the connecting part is connected with the outer edge of the connecting bottom, the connecting bottom comprises a connecting flange area and a thin-wall deformation area, the connecting flange area is located in the center of the bottom, and the thin-wall deformation area is located in the middle of the connecting flange area. And the thin-wall deformation area is connected with an external thin-wall deformation area, and the thin-wall deformation area is S-shaped. The S-shaped flexible gear structure of the harmonic reducer is small in axial size and simple in structure, stress concentration is effectively reduced, and the service life is prolonged.
