Abstract:
A concise
mathematical model for hobbing non-circular gear is set up. Based on the
point that the speeds of the hob and gear are equal along the tangent
line at the cutting point, which is consistent with pure rolling between
the pitch curves of the hob and gear, a group of equations is set up.
The concise mathematical model for hobbing non-circular gear is obtained
form the group of equations with further simplification, and it is a
3-axes simultaneous control structure. By using computer graphic
simulation, the concise mathematical model is applied to demonstrate the
hobbing process and result dynamically. Features of the hobbed gear can
be observed from the graphics, and so become convincing basis for
correct design and cutting.
