Turn do not have interior rollaway nest on the outer idler wheel raceway of support wheel shaft or on plug.
Compared with prior art, the present invention its advantage is that：
1, rotary tool can be entered internal tooth surface parts by hatch frame and is processed, and be obtained with lower rotary speed
Higher processing linear velocity, same or smaller szie tool processes limitations must be used by breaking through small size geometric properties on part
Property, obtain better processing quality；
2, due to the raising of processing linear velocity so that life tools and processing efficiency are greatly improved；
3, using many places inner supporting structure, the rigidity of tool is more preferable, and error-correction model degree is high, is conducive to acquisition high-precision and adds
Work.
