Description
Technical field
The present invention relates to existing three ring flat-plate few teeth difference braking technique fields, a kind of three-ring speed reducer.
Background technique
After 1985 Chongqing iron and steel designing institute " three ring speed reduction gearings " (85106692), three-ring speed reducer patent application does not have interruption, as: (1) Dalian University Of Communications " Double-crank annular plate cycloidal pin-wheel speed reducer " 96207312 and " Double crank ring-plate type cycloid pinwheel planetary speed reducer " 02231994; (2) Shanghai Institute Of Technology's " internal gear plate type planet gear driving device " 200420107933; (3) straight scientific and technological engineering company " the imitative method of elimination three-ring speed reducer gear engagement impact " 200810053910 in sky, Tianjin weight; (4) Liaoning Technical University's " full balanced dual drive three-ring speed reducer " 200920012531 etc.The subject matter of background technique is: produce vibration during running, so that " compare with the state-of-the-art conventional needle cycloidal pinwheel planetary gear speed reducer of Contemporary Japanese, its power transmitted and moment of torsion can increase by more than 1 times.The expection of this achievement can become the advanced speed reduction gearing of the industrial fields such as iron and steel, oil, chemical industry, lifting transport, building, lathe, rubber plastic, water treatment, food and national defence in 21 century." " Double crank ring-plate type cycloid pinwheel planetary speed reducer " fail achieve one's goal and abandon utility model patent.
Summary of the invention
The object of the invention provides stable drive three zone plate speed reducer, a kind of three-ring speed reducer.
Technological scheme:
Research finds that vibrative main factor is in background technique, all adopts roller bearing in ring flat-plate two input shaft bore.Liu Zejiu " rolling bearing application manual " 720 pages: " in actual use bearing end-play by have influence in bearing load diatibution, vibration, noise, friction torque and life-span.", 724 page table 4-45 cylindrical hole roller bearing radial internal clearancies: during bearing hole 65-160, basic group play 0.04-0.12 (mm).Therefore, eliminating three-ring speed reducer vibration optimum scheme is roller bearing is improved to double-row conical bearing or two back-to-back combinations of single-row tapered roller bearing, the radial internal clearance of bearing is controlled to zero or close to zero by accurate Calculation spacer ring thickness.
Beneficial effect
According to existing three-ring speed reducer, creativeness of the present invention is: (1) smooth running, thus the unnecessary employing of more than SH500 type expensive ends of the earth motor, and can adopt four or 6-pole motor; (2) process for machining performance is good.
