Abstract
An active form-grinding method is proposed to obtain excellent and stable contact
performance of cylindrical gears by designing modification forms based on a predesigned
controllable second-order transmission error function. First of all, a predesigned second-order
transmission error polynomial function is assigned to the gear drive. Mathematical models of
modified tooth surfaces that can describe their local deviation and ease-off topography are
then obtained with the predesigned second-order transmission error function. Moreover, the
form-grinding wheel’s profile equation, the coordinate transformation matrix during formgrinding,
and settings of computer numerical control form-grinding programs for this active
design method can be determined. This approach is ultimately conducted on three involute
cylindrical gear pairs to demonstrate its feasibility and effectiveness.
