AI Technical Summary

Technical Problem

During the assembly of the harmonic reducer, the cooperation between the wave generator and the flexspline causes stress concentration, which can easily cause the flexspline to crack or break, reducing its service life.

Method used

Design a wave generator, including a cam and a flexible bearing. The outer peripheral wall of the cam is inclined along the axial direction to form an inclined surface. The flexible bearing is sleeved outside the cam and an interference fit with it. The outer peripheral wall of the flexible bearing is also inclined to match the shape of the flexspline. External expansion deformation creates a surface contact state, reducing stress concentration.

Benefits of technology

It effectively reduces the stress concentration between the wave generator and the flexspline, increases the service life of the flexspline, and further extends the use of harmonic reducers and robots by increasing the meshing tooth width and reducing the gear segment expansion angle. life.
