Further, described lug is provided with for the fixing through hole of inner blade superposition riveted joint.
Further, described inner blade is by riveted joint, welding, rolling or gluing fixing.
Another object of the present utility model, be to provide a kind of planetary speed reducer with above-mentioned ring gear, comprise the sun gear of enclosing cover and formation planetary reduction gear, planetary pinion, planet stent and ring gear, described ring gear is superposed by two or more inner blade and fixedly forms, described inner blade is provided with lug and the through hole for inner blade riveted joint being fixed, and described enclosing cover inwall is provided with the groove for accepting lug.
Another object of the present utility model, be to provide a kind of single hop big retarding with above-mentioned ring gear to compare planetary speed reducer, comprise the sun gear of enclosing cover and formation planetary reduction gear, planetary pinion, planet stent and ring gear, described ring gear comprises input end ring gear and output terminal ring gear, and described planetary pinion engages with sun gear, input end ring gear and output terminal ring gear simultaneously.
Further, described input end ring gear is riveted by two or more inner blade and is formed, and described inner blade is provided with lug.
Further, described output terminal ring gear is formed by two or more inner blade rolling or be welded and fixed.
Compared with prior art, the beneficial effects of the utility model main manifestations is:
Different from ordinary gear, existing ring gear is owing to limiting by processing technique, and its manufacture cost remains high always, causes the on the high side of existing planetary speed reducer.The utility model significantly can reduce the processing cost of ring gear, raise the efficiency, make to be no matter that the manufacture of the soft flank of tooth or hardened face gear is simplified, the particularly processing of internal tooth, replaces traditional gear hobbing process with punch press and grinding tool, and teeth is processed, Gear Shaping, draw tooth to process, roll flute is processed, Linear cut Gear Processing.Its application area covers involute internal-external gear, the pin tooth tooth cover of Arc Cycloid, pin tooth external tooth etc., makes the propelling of industry 4.0 more smooth and easy.

Embodiment
Below in conjunction with accompanying drawing, detailed explanation and explanation are done to structure of the present utility model, but be not the restriction to the utility model structure.
Please refer to Fig. 1 ~ 3, a kind of ring gear of planetary speed reducer, is superimposed by two or more inner blade 1 and fixedly forms.Inner blade 1 is the metal cirque of band internal tooth, and annular edge is provided with the arc notch 2 for Fold additon location.
When the internal tooth of inner blade is straight internal tooth, inner blade 1 is provided with lug 3, is arranged in planetary speed reducer shell to facilitate ring gear.Lug 3 is provided with through hole 4, and rivet by fixing for inner blade superposition through through hole 4, also can adopt pin or screw to replace rivet to be fixed up by the multiple inner blades be superimposed, form lug ring gear 5, as Fig. 2.Through experimental results demonstrate, by rivet, pin or screw by multi-disc inner blade lug ring gear 5 fixedly, its stability is identical with the ring gear formed together.
When the internal tooth of inner blade is oblique internal tooth, inner blade can not arrange lug, need be fixed by welding, cold-hot pressure rolling or the gluing inner blade by some formation certain thickness ring gears.If ring gear need be applied on larger reduction ratio speed reduction, then need by cold-hot pressure rolling, multiple inner blade to be fixed, to meet the demand of its rotary torque.Through experimental results demonstrate, by cold-hot pressure by multi-disc inner blade laminating ring gear 6 fixedly, its stability is identical with the ring gear formed together, as Fig. 3.
