Description
Technical field: the present invention relates to a kind of Transmission Mechanism of Planetary Gear System without planet carrier (tie-rod, pivoted arm), particularly a kind of by planet wheel as leading dirivig member, planet wheel is directly installed on driving wheel sun gear, improve transmission efficiency without planet carrier Transmission Mechanism of Planetary Gear System.
Background technique: at present, known planetary gear train transmission, just be used for realizing gear, obtain larger velocity ratio, realize turn to and along separate routes transmission and as the composition and decomposition of motion, realize relatively high power transmission etc., can not realize the raising of transmission efficiency.Planet wheel, planet carrier do not possess leading transmission agency.Planet wheel is supported by planet carrier, has increased dirivig member, strengthens the loss of manufacture cost and power.
Summary of the invention: in order to change the state of the art, the invention provides and a kind ofly by two or more, without frame planetary gear train, formed, planet wheel is directly installed on driving wheel sun gear, and planet wheel is as leading dirivig member transferring power, without the Transmission Mechanism of Planetary Gear System of planet carrier; According to Comlex-locus and mechanics principles such as planet wheel not only rotation but also the characteristic revolving round the sun and the different cycloids of the upper each point of wheel, cycloid, space time curves, on planet wheel in input train, instantaneous on the input direction select time of power, the input point of relatively constant power, i.e. force bearing point on space; Determine under the condition that original wheel for inputting (axle), terminal output wheel (axle) linear velocity are equal and adjust active force arm, realized the increase of input torque, improved transmission efficiency.
The technological scheme that technical solution problem of the present invention adopts is: an input star wheel series and an output planetary train are installed in the geometric centre axes overlapping; In input train, widen planet wheel do not have planet carrier to be directly installed on moving axis sun gear and with the outer gearing of dead axle sun gear, moving axis sun gear in mesh, the moving axis sun gear that planet wheel is not installed is original wheel for inputting (axle); In output wheel train, planet wheel be directly installed on driving wheel sun gear and with input train in the outer gearing of planet wheel widened section, also can be without engagement, diaxon rolls, in output wheel train, moving axis sun gear is terminal output wheel (axle); Two planet wheel contact pointss are input points of working force, claim force bearing point, force bearing point will the planet wheel in input train on, working force action direction selects; Force bearing point is less than planet wheel radius to the distance of planet wheel and dead axle sun gear contact points, is greater than 0, that is to say that the angle of force bearing point, input train planet wheel and fixed wheel contact points claims stressed angle, and stressed angle is greater than 0 °, is less than 60 °; Choose reasonable the input point of power, strengthened the initiatively arm of force, reached input torque increase, improve transfer efficiency, save the object of Input Forces.The driving wheel sun gear that planet wheel is installed in input in train is directly original wheel for inputting (axle), remove with planet wheel in the driving wheel wheel for inputting that meshes, its effect is identical.
For generation efficiency synergistic effect, above-mentioned driving mechanism can complete independent utility, input, the output wheel train that can also increase again one or more same structures becomes complete independently Multi-stage transmission mechanism, different is while increasing again, terminal output wheel is connected with the original wheel for inputting of next stage, continues as wheel for inputting.No matter how many grades of connections, initial input wheel (axle) and terminal output wheel (axle) also respectively have one.
Beneficial effect of the present invention is: novel form, runnability is reliable and stable, simple in structure, is widely used.Effects of energy saving and emission reduction is obvious.
Accompanying drawing explanation: the invention will be further described below in conjunction with Figure of description.
Fig. 1 is plan view of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the plan view that Fig. 1 inputs a sun gear of train.
Fig. 4 is the left view of Fig. 3.
In Fig. 1, the geometrical axis 1. overlapping, 2. input train planet wheel, 3. moving axis sun gear, 4. dead axle sun gear, 5. moving axis sun gear, 6. output wheel train planet wheel, 7. moving axis sun gear, 8. two planet wheel contact pointss, 9. input train planet wheel and dead axle sun gear contact points.
Embodiment:
In the embodiment shown in fig. 1,2,3,4,5 is input train, and 6,7 is output wheel train.(5) initial input wheel (axle) docks with power engine, and 7 terminal output wheels (axle) dock with working machine, and 5 drive 2,2 to drive 6,7.The 2nd, add wide gear and 3 and 6 and 5 outer, outer, interior engagements, widened section and 6 also can directly roll by diaxon.The 8th, the input point of power, force bearing point will be at 5 force direction, and stressed angle (angles in 8,9 and 2 centers of circle) are greater than 0 °, are less than in the interval of 60 ° and select.The 2nd, distortion lever, 9 fulcrums, according to regulations and parameters principle, during 30 °, 45 °, stressed angle, moving, resistance arm ratio is respectively 3.86/1 and 2.61/1.According to Transmission Ratio of Planetary Gear Trains principle, n

1respectively the sun gear number of teeth ,-turn to.If 3 the number of teeth equals 100,2=10,5 the number of teeth=120 (modulus is consistent) so, and 5 and 4 velocity ratio=1.83,7 is consistent with 5 rotating speeds.The radius that is 60,7 due to 5 radiuses is greater than 50, is less than 55.Therefore, comprehensive speed ratio and moving, resistance arm is poor, has realized the increasing without planet carrier planetary gear train transmission input torque.
In specific embodiment shown in Fig. 3: 3 directly as original wheel for inputting (axle), and 3 is consistent with 7 velocity ratios, during 30 °, 45 °, stressed angle, 2 moving, resistance arm ratio is respectively 1.93/1 and 1.31/1.Therefore, comprehensive speed ratio and moving, resistance arm is poor, is realizing manufacturing and the transmission cost of having saved planet carrier when transmission input torque strengthens.
7 can continue as 5 or 3 of next same mechanism again according to actual needs, form multistage without frame Transmission Mechanism of Planetary Gear System, finally only have an original wheel for inputting (axle) and a terminal output wheel (axle), because the structure of every grade is identical, so do not mark accompanying drawing in this specification.
For stability of rotation and reduction tooth damage, planet wheel can be several being evenly distributed on driving wheel sun gear, because drive mechanism is identical, does not mark accompanying drawing in this specification.
Key technology of the present invention is the selection of force bearing point and without planet carrier setting, no matter driving mechanism by how many grades of trains form, how mesh form to change, as long as adopt all the belonging in right of the present invention of key technology of the present invention.
