AI Technical Summary
Existing technologies in harmonic gear transmissions fail to effectively consider the impact of flexible gear cup spatial deformation on motion patterns, resulting in tooth surface design that is difficult to conform to actual motion patterns, thus affecting transmission accuracy and lifespan.
By establishing the meshing line, coordinate transformation matrix, and conjugate curve, the tooth surface of the flexure is constructed. Taking into account the deformation of the flexure cup, a high overlap ratio harmonic reducer tooth surface is generated, which reduces the inter-tooth contact stress and improves the transmission accuracy and service life.
The harmonic gear tooth surface design achieves higher overlap and lower contact stress, significantly improving the transmission accuracy and service life of harmonic gears.
