Device 22 presses the rotating speed to stable drive ratio relation control servomotor 11 again, and encoder III 23 and controller 22 realize servomotor
11 closed-loop control.Finally, axial feed hydraulic cylinder 14 promotes gear blank mounting and clamping system and pressure to divide tooth system axial on guide rail 1
Slide, gear blank 6 pass completely through a left side roll wheel 24 and the right side roll wheel 21 when, complete it is axially rolled.
Since this pressure gear device is to control its rotating speed according to the gearratio for rolling wheel and gear blank, each tooth of wheel is rolled
Tip circle arc can avoid indentation sliding when freely dividing tooth, random tooth, the hair of multiple tooth or few tooth phenomenon at the same time in place with gear blank groove
Raw, therefore, advantages of the present invention and good effect are as follows：
(1) when avoiding large module gear rolling, tooth is freely divided repeatedly to debug the appearance of phenomenon, processing efficiency substantially carries
It is high；
(2) generation for phenomena such as avoiding causing to roll form of gear tooth fracture because of random tooth, multiple tooth or few tooth, improves and rolls the wheel longevity
Life；
(3) any profile modified gear can be rolled out.
