A flexspline structure of a harmonic reducer is disclosed, comprising a circular spline, a flexspline and a wave generator. The flexspline is manufactured from tubular material into a thin-walled cylinder with external gear and is assembled with the circular spline. The wave generator is assembled with the flexspline and a power source, so the flexspline deforms and engages with the circular spline partially. The flexspline is fixed while the circular spline is connected to an output shaft. When the power source drives the wave generator to rotate, the flexspline also drives the circular spline and the output shaft to rotate simultaneously. The flexspline in the disclosure is manufactured directly from tubular material to eliminate the forging process in the conventional flexspline processing, so the material wear is reduced and processing time of lathing and gear hobbing are decreased noticeably as well. |
