Abstract:
The wear and destruction appearances of hobs are researched. The
reasons of the wear and destruction of hob are analyzed. And the
influence of the change of the hobbing force and the hobbing
temperature on the wear and destruction of hob in gear hobbing
is also analyzed. In gear hobbing, the main wear mechanisms are
adhesion and ploughing when cutting the 20CrMnTi gear using
W18Cr4V high-speed steel hob.
Key words:
Gear hob Gear hobbing Wear and destruction Wear mechanism
