Base 901 is concatenated and fastened with latch segment 903 and locking nut 904；Top 601 and clamping hydraulic cylinder 150 by gear blank clamping mechanism
900 clamp.Then, left radial feed hydraulic cylinder 3 promotes a left side to roll wheeling support 4, wheel 5 and left servomotor 17 are rolled in left slide rail 2 in a left side
On move to reach rolling position；Meanwhile right radial feed hydraulic cylinder 12 promotes the right side to roll wheeling support 11, wheel 10 is rolled on the right side and right servo electricity
Machine 14 moves to rolling position on right slide rail 13；Left and right servomotor 17,14 starts simultaneously, and wheel 5 is rolled on a drive left side respectively and the right side is rolled
The rotation of wheel 10.Finally, axial feed hydraulic cylinder 7 promotes gear blank clamping mechanism 900 to be slided on axial guidance 8 with specific speed,
Gear blank clamping mechanism 900 pass completely through a left side roll wheel 5 and the right side roll wheel 10 when, complete it is axially rolled.Its rollforming moves schematic diagram
As shown in Figure 3,4.
Wheel axis and gear blank diameter parallel are rolled in existing gear rolling forming technology, rolls the load born of wheel gear teeth edge all the time
Transverse tooth thickness direction.The central axis of wheel axis and gear blank is rolled in the present apparatus in 90 ° of spatial intersecting, rolls what the wheel gear teeth were born in formation zone
Load is mainly compression, rather than bending stress.Therefore, advantages of the present invention and good effect are as follows：
(1) improve the shaping flowing of gear blank metal, reduce the roll-force in forming process；
(2) tooth bending stress of helical form tooth form rolling wheel is reduced, the wheel life-span is rolled in raising；
(3) under equal conditions, the modulus scope of steel gear rollforming is expanded.
