AI Technical Summary
The hat-shaped flexible wheel is difficult to position during gear hobbing or gear shaping, and is prone to deformation, making it difficult to achieve the design accuracy and affecting the transmission accuracy and service life of the harmonic reducer.
A positioning device is designed, including a positioning device body and an annular conical sleeve. By cooperating with the expansion outer circle and the positioning outer circle, combined with the use of elastic groove and locking nut, reliable positioning of the hat-shaped flexible wheel is achieved to prevent deformation.
High-precision positioning of the hat-shaped flexible wheel was achieved, ensuring that the machining accuracy met the design drawings, preventing deformation, and improving the transmission accuracy and service life of the harmonic reducer.
