Sliding wedge gear that achieves high meshing efficiency

摘要

A slide spline (10) includes a circular spline (20), a flex spline (30) and a wave generator (40) that abuts against the flex spline (30). A special parameter design that corrects the amount of curvature of the Wave Generator (40) achieves high meshing efficiency between the Circular Spline (20) and the Flexspline (30), improving translation accuracy and reducing the average load.
