AI Technical Summary

Problems solved by technology

The speed regulating mechanism of this cone-disc continuously variable transmission has a large axial dimension, a complex structure, and is not easy to process.

And because the nut needs to connect the movable cone through the movable cone bearing of the speed regulating mechanism, the movable cone bearing of the speed regulating mechanism will bear relatively large pressure and friction force, which will cause excessive heat generation of the movable cone bearing of the speed regulating mechanism , affecting the service life of the speed regulating mechanism
