Abstract
The present invention relates to a dowel pin uniformly-loaded double-group cycloidal gear epicyclic transmission mechanism, including four identical cycloidal gears, eccentric bearing, or eccentric sleeve and bearing, input shaft, pin gear and dowel pin. It is characterized by that the respective centre Opi of four identical cycloidal gears are uniformly distributed on the cycle using shared pin gear of the cycloidal gear epicyclic transmission mechansm as centre Oc and using eccentric distance A as radius Rai, and its error is plus or minus 5 deg. All the OPi are mutually not coincident axially are the front and rear positions of said four identical cycloidal gears are regardless.
Description
Technical field
This technology belongs to epicyclic transmission mechanism, and it is widely used in the mine, metallurgy, and shipping, traffic, lifting, chemical industry, building is on the gearing equipment of multiple industries such as weaving.
Background technique
Existing double-group cycloidal gear epicyclic transmission mechanism is not realized dowel pin uniformly-loaded (Fig. 2, Fig. 3), its structure is: give capacity eccentric bearing 2 or eccentric bushing+bearing by input shaft 3 transmitting torques, cycloidal gear 1 revolves round the sun and rotation as star-wheel, by cycloidal gear moment of torsion is passed to pin 5 (Fig. 4) then.This installation form is, the center of circle Op1 of any one cycloid wheel of back group or Op2 are in twos to overlap from A to seeing with the center of circle Op3 or the Op4 of any one cycloid wheel of preceding group, and Fig. 2 and Fig. 3 have the situation of coincidence; Fig. 4 and Fig. 5 are that capacity eccentric bearing spread pattern Fig. 6 and Fig. 7 are the eccentric bushing spread patterns.This structure can not play dowel pin uniformly-loaded effect, that is born on each pin makes a concerted effort except that the position of meshingangle=90 ° all not on the tangent line of pin turning circle, and bearing periodically variable making a concerted effort, it is maximum to make a concerted effort when meshingangle=90 °, so very big to the shear fracture of pin.The double-group cycloidal gear of two groups of cycloid wheel speed reducers does not rationally distribute, and causes many pins stressed excessive and uneven year, unreasonable structure, and cycloidal gear passes to the resultant direction of pin not in tangent direction.
Summary of the invention
The utility model is the not problem on tangent direction of making a concerted effort that solved above-mentioned pin uneven year and pin is suffered, and a kind of dowel pin uniformly-loaded double-group cycloidal gear epicyclic transmission mechanism of new structure is provided.
The utility model provides a kind of dowel pin uniformly-loaded double-group cycloidal gear epicyclic transmission mechanism, include four identical cycloidal gears 1, capacity eccentric bearing or eccentric bushings and bearing 2, input shaft 3, pinwheel 4, pin 5, four identical cycloidal gears 1 center of circle Opi separately is distributed on many pinwheels 4 center O c with the cycloid in planet driving mechanism, with throw of eccentric A is on the circle of radius R ai, error ± 5 degree; Each Opi does not axially overlap each other; No matter and the front and back position of four identical cycloidal gears; A double-group cycloidal gear mechanism, its cycloidal gear has only with a kind of number of teeth, with a kind of speed ratio.
It is dowel pin uniformly-loaded that such structure can reach.
Throw of eccentric A=Rai,
That is: Ra1=Ra2=Ra3=Ra4;
——— ——— ——— ———
Ra1＝Oc?Op1； Ra2＝Oc?Op2； Ra3＝Oc?Op3； Ra4＝Oc?Op4；
Cycloidal gear angle of distribution β i wherein:
∠Op1 Oc?Op2 ＝β1；
∠Op2 Oc?Op3 ＝β2；
∠Op3 Oc?Op4 ＝β3；
∠Op4 Oc?Op1 ＝β4；
The relation of each angle of distribution of cycloidal gear is:
β1+β2+β3+β4＝360°。
Cycloidal gear angle of distribution β i is 90 ° of angles, and is positive and negative in 0 ° to 5 ° scope, promptly on the circle that the uniform or approximate throw of eccentric A that is distributed on them of the center of circle Opi of each cycloid wheel is radius R ai in 360 ° scope (each Opi does not axially overlap each other).
This figure is exactly a dowel pin uniformly-loaded double-group cycloidal gear mechanism, no matter arrange the front and back of each cycloid wheel.
The utility model has solved the uneven problem of carrying of pin of double-group cycloidal gear, double-group cycloidal gear mechanism makes dowel pin uniformly-loaded, the dowel pin uniformly-loaded radial dimension of double-group cycloidal gear mechanism that makes reduces significantly, reduced volume not only, weight reduction, and the resultant direction that each pin bore is optimum orientation, and the size of making a concerted effort that each pin is born is the same.This two cycloidal gear teeth mechanism that organizes, more reasonable structure, compacter, operating condition is more perfect, and pin is not easy fracture.And improved the stationarity of running, prolonged working life, reduced cost of production and cost of transportation, reduced transport space.
