The utility model is formed by that two swinging planetary gears are respectively arranged on two upper cranks of an input eccentric shaft; driven eccentric shafts which are arranged on the swinging planetary gears are parallel with the input eccentric shaft with whose eccentricity is equal to the eccentricity of the driven eccentric shafts; the supporting seats of the driven eccentric shafts are fixed on a differential connecting board; the two swinging planetary gears are respectively engaged with internal tooth rings on a machine casing and an output shaft, consequently realizing the differential synthesis of the two swinging planetary gears, and driving ratio can be changed between one and 40 thousands. The utility model has the advantage that the utility model has compact structure and large driving ratio, and can be applied to various mechanical driving devices needing the large driving ratio.
Description
The utility model belong to use in the mechanical transmission, have than the compound swing gearing with small teeth differenc of the differential of big speed ratio.
In mechanical transmission, for boundary dimension and the weight that reduces transmission device, increase the velocity ratio of driving mechanism, the main method of employing is exactly that the common transmission that will have the dead axle line gear changes Gear Planet Transmission or swing transmission into." the compound swing gearing with small teeth differenc " that Chinese patent (patent No. is 93244454.7) provides has rational in infrastructure, simple, easily manufactured and characteristics such as velocity ratio is bigger.The velocity ratio of this device is relevant with the number of teeth of ring gear and planetary number of teeth difference of swing and ring gear.Number of teeth difference is more little, and the ring gear number of teeth is many more, and its velocity ratio is big more.Because the number of teeth difference minimum of this device is 1, the number of teeth of ring gear can not be too big, so the velocity ratio that increases this device also is restricted, general velocity ratio is in 200.
But the utility model is design at the deficiencies in the prior art a kind of make velocity ratio from 1 to more than 40,000, the compound swing gearing with small teeth differenc of differential of output shaft positive and negative direction rotation.
The utility model is realized by following measure.The input shaft of this device is the eccentric shaft that two crank throws are arranged, and the throw of eccentric direction of two crank throws is opposite.On casing, the other end is concentric with output shaft by bearing fixing for one end of eccentric shaft, by bearing fixing on output shaft.On the eccentric diameter of axle of two crank throws of this eccentric shaft, a swing planetary pinion is housed respectively.On the center diameter of axle of this eccentric shaft, a differential connecting plate is housed respectively near both sides, crank throw place.On two swing planetary pinions, two driven eccentric shafts that parallel with first eccentric shaft are housed also.The throw of eccentric of driven eccentric shaft equates that with first eccentric shaft the eccentric direction during assembling is identical with first eccentric shaft.The bearing of two driven eccentric shafts is separately fixed on two differential connecting plates by bearing.Two differential connecting plates are fixed into as a whole by connecting rod.A swing planetary pinion is meshed with ring gear on being fixed on casing inner wall; Another swing planetary pinion is meshed with ring gear on the output inner gear axle.
When the input eccentric shaft rotated by certain direction, two driven eccentric shafts were then with identical speed rotation.Two planetary center lines of swing then rotate with unequal angular velocity, and swing planetary pinion body is then at the uniform velocity swung around the center line of ring gear.Because the ring gear that is meshed with a swing planetary pinion is fixed on the casing inner wall, can not rotate, so two differential connecting plates that support driven eccentric shaft drive two swing planetary pinions and rotate in the opposite direction with the few determined angular velocity of tooth difference transmission of compound swing.The swing planetary pinion that is meshed with the ring gear of output shaft on the one hand, drives the output shaft ring gear and rotates, on the other hand, to motion in the other direction, realized the synthetic of two swing planetary gear differentials motion with the differential connecting plate thus, made output shaft by the speed motion after synthetic.
Driven eccentric shaft in the utility model can be two, also can be a plurality of, can determine according to the structural requirement of type.Crank throw on the input eccentric shaft also can have only one, and a swing planetary pinion only is installed, and another swing planetary pinion then supports and drive swing by two driven eccentric shafts.If the velocity ratio of this device does not need very big, the swing planetary pinion that is meshed with ring gear on the enclosure wall can be processed into halo, be not meshed with ring gear, only use as stabilizer.Simultaneously differential connecting plate and casing are fixed together, realize the few tooth difference transmission of the compound swing of single-stage of another swing planetary pinion and output inner gear axle ring gear, its velocity ratio can be in 200.Two differential connecting plates can merge and are placed between two swing planetary pinions.Gear can adopt profiles of tooth such as involute, cycloid or circular arc.
The utility model has the advantages that, compact structure, velocity ratio is big, and velocity ratio can change arbitrarily from 1 to 40,000.The sense of rotation of output shaft can with input shaft select veer identical or opposite.The transmission direction of device is reversible.
Figure of description is a structural representation of the present utility model, and (1) is ring gear among the figure; (2) be connecting rod; (3) be driven eccentric shaft; (4) be the differential connecting plate; (5) be casing; (6) be the input eccentric shaft; (7) be the swing planetary pinion; (8) be the swing planetary pinion; (9) be the differential connecting plate; (10) be the output inner gear axle; (11) be ring gear.
Below in conjunction with a description of drawings embodiment of the present utility model.
