The method is universally applicable to the process of tooth - profile of various dies and spur gears.
该方法对各种模具和圆柱齿轮的渐开线齿形加工均适用。

The forming recesses (1, 3) of a lower die (2) and an upper die (4) are formed to have a semi-oval profile so as to provide a forming space S almost oval in section with the dies closed.
If the rolling dies are not preciously designed or the machining operation is not properly implemented, there is an influence on the profile accuracy, noise and service life of the workpiece gears.
