Description
Affiliated technical field
The utility model relates to a kind of mechanical transmission, the particularly a kind of two interior engagement balanced type little tooth difference speed reducer that can realize the big reduction of speed ratio of coaxial line input output.
Background technique
The retarder of the same type of extensive use at present is harmonic gear reducer and cycloidal-pin wheel retarder.The common drawback of these two kinds of retarders is that part manufacturing process is poor, and very big such as the flexbile gear in the harmonic gear reducer, wave-generator difficulty of processing, the cycloid wheel in the cycloidal-pin wheel retarder needs special device to process.This just makes the manufacture cost of above two kinds of retarders higher relatively, does not have the general machining factory of special manufacturing process and special device not produce.Existing involute planetary gear retarder adopts the displacement engagement for solving interference problem, and the result has caused pressure angle increase, bearing load increasing, efficient to reduce.In addition, cycloidal-pin wheel retarder and involute planetary gear retarder all do not have well to solve dynamic equilibrium problems.
Summary of the invention
The purpose of this utility model is, poor at existing harmonic gear and cycloidal-pin wheel retarder anufacturability, as to need special device shortcoming, a kind of the same with the cycloidal-pin wheel retarder big reduction of speed ratio speed reducer that can realize the coaxial line input output with harmonic gear is provided, anufacturability is good, do not need special device, cost is low two in engagement balanced type little tooth difference speed reducer.
The technical solution of the utility model is: utilize the two pairs of internal gear pairs to realize reductions of speed and motion output, utilize again other two pairs with interlace 180 ° the dynamic and static balance and the driving force balance of internal gear pair realization whole drive system of aforementioned external teeth wheel.Be specifically described as follows, be contained on the excentric sleeve a duplicate gear one of them with fixing internal gear engagement, both numbers of teeth are identical, thereby constitute the translational motion that zero tooth difference transmission realizes duplicate gear; Another gear in this duplicate gear and the ring gear engagement that is fixed on the output shaft, both constitute few tooth difference transmission output of will moving simultaneously; Dynamic and static imbalance and driving force imbalance problem during for the solution high speed rotating, add a pair of gear train that is coupled to by 4 pins again, its modulus, the number of teeth and other gear parameter are in full accord and interlace 180 ° with duplicate gear and to install with duplicate gear respectively, and its 4 pins pass 4 corresponding on duplicate gear holes; Eccentric and the dislocation of duplicate gear and gear train is realized by the eccentric bushing that connects firmly on input shaft.The output internal gear pair is ultrashort tooth, be that addendum coefficient can be as small as 0.1～0.2, so needn't displacement, can avoid that the working pressure angle that caused by displacement is excessive, transmission efficiency is crossed low problem, thereby solve the interference problem of few tooth difference transmission, the overlap coefficient that brings thus can be solved by the multiple tooth engagement effect of interior engagement driving less than 1 problem.
The beneficial effects of the utility model are, with two pairs of interior engagement duplicate gears of 180 ° of interlacing realize slowing down, motion output, and the fine equilibrium problem that solved.Utilize the ultrashort tooth engagement of invariant position to solve interference problem, thereby avoided the pressure angle increase that causes by displacement, the problem that bearing load strengthens, efficient reduces.Its reduction of speed is than flexible design, and is simple in structure, and whole device does not have difficult processing accessories, do not need special device, and general machining factory can make.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
Below in conjunction with drawings and embodiments the utility model is further specified; In the accompanying drawings, input shaft 1 is bearing in bearing 2, the bearing 16, drives eccentric bushing 3, the eccentric bushing 18 of two symmetries by key 19; Supporting duplicate gear 6 by bearing 4, bearing 5 on eccentric bushing 3, the eccentric bushing 18, the right-hand member gear of duplicate gear 6 and fixedly ring gear 7 engagements, the number of teeth is identical, and the left end gear of duplicate gear 6 and 11 engagements of movable ring gear, ring gear 11 connects firmly with the output shaft 12 that is supported on bearing 13, the bearing 15; The gear 8 that is supported on the bearing 20 is identical with the right-hand member gear parameter of duplicate gear 6, the gear 10 that is supported on the bearing 17 is identical with the left end gear parameter of duplicate gear 6, gear 8 and gear 10 are linked to be integral body by the corresponding aperture that 4 pins 9 pass on the duplicate gear 6, and, promptly interlace 180 ° with duplicate gear 6 eccentric symmetric arrangement; Bearing 2 is contained in the hole of input end cap 22, and bearing 13, bearing 15 are contained in the hole of output end cap 14, and input end cap 22 and output end cap 14 connect by bolt and support 21; Duplex left end gear and gear 10 is ultrashort tooth with the gear pair that movable ring gear 11 constitutes, and its addendum coefficient can be 0.1～0.2, and overlap coefficient solves less than 1 the problem multiple tooth engagement effect by internal gear pair.
When input shaft 1 rotates, drive eccentric bushing 3, eccentric bushing 18 rotations by key 19, rotate around the input shaft center at center through bearing 4, bearing 5, bearing 17, bearing 20 driving duplicate gears 6 and gear 8, gear 10, because the right-hand member gear of duplicate gear and gear 8 are with fixedly ring gear 7 numbers of teeth are identical, thereby duplicate gear 6 and gear 8, gear 10 have only revolution not have rotation, promptly does symmetrical translation under the effect of fixing ring gear 7; The left end gear of duplicate gear 6 and 11 engagements of movable ring gear, gear 8 then also meshes with movable ring gear 11 via pin 9 driven gears 10, by the left end gear of duplicate gear 6 and gear 10 number of teeth difference relation, make movable ring gear 11 rotate and drive output shaft 12 output of will moving with movable ring gear 11.Because each gear, bearing are symmetric arrangement, centrifugal force is cancelled out each other, and the driving force on the gear also cancels out each other, and has only moment of torsion output.
