Description
Technical field: the present invention relates to a kind of planetary gear train transmission system, specifically a kind ofly changes torque and does not have carrier to improve the duplex variable planet gear transmission system of transmission efficiency.
Background technique: at present, known planetary gear train transmission, be just used as speed change, turn to, along separate routes, the composition and decomposition etc. of power, planet wheel is not as leading dirivig member; Planet wheel is supported by planet carrier, adds dirivig member, increases raw material manufacture cost and power transmission cost; Input torque can not change, and the raising of transmission efficiency can only lean on the reduction of speed to realize.
Summary of the invention: in order to change the state of the art, the present invention take planet wheel as research and development objects, by double-planetary gear radius and the change exporting moving axis sun gear radius, strengthens initiatively pivoted arm, improves transmission efficiency.Specifically provide a kind of to be made up of row of variables star wheel series, planet wheel is as leading dirivig member, and sun gear substitutes the bending moment planet gear transmission system of planet carrier.Goal of the invention one reduces parts, reduction material, processing, transmission cost; Two is strengthen input torque, saves energy consumption, improves transmission efficiency; Three is expand planetary gear train transmission using scope, can be widely used in the mechanical transmission of all kinds of power machine; It is according to planet wheel characteristic and mechanics principle, the input point of the power of instantaneous on select time on planet wheel, space relative constancy; The active pivoted arm of planet wheel is strengthened by duplex row of variables star-wheel semidiameter; Adjustment wheel for inputting and terminal output wheel angle speed, differential surface speed, achieve increase input torque, improve the object of transmission efficiency.
The technological scheme that technical solution problem of the present invention adopts is: duplex bending moment planet gear transmission system, comprise the line of input star wheel series in the geometrical central axis 1 of the coincidence be connected with ectosome and moving axis output wheel 2, it is characterized in that: in input train, have moving axis sun gear 3, dead axle sun gear 4, with have A, the duplex row of variables star-wheel 5 of B two wheel, described duplex row of variables star-wheel 5 does not have planet carrier to be directly installed on moving axis sun gear 3, A wheel wherein and dead axle sun gear 4 internal messing, B wheel and moving axis output wheel 2 outer gearing, also can internal messing, moving axis sun gear 3 and moving axis output wheel 2 are initial input wheel and terminal output wheel, B in duplex row of variables star-wheel 5 takes turns radius and is less than A wheel radius, the variable of duplex row of variables star-wheel 5 refers to and is not changing moving axis sun gear 3 radius, and the geometry axle center 1 namely not changing moving axis sun gear 3, under the distance prerequisite in the axle center 6 of duplex row of variables star-wheel 5, changes A wheel and B in duplex row of variables star-wheel 5 and takes turns radius, after A wheel in duplex row of variables star-wheel 5, B take turns radius change, dead axle sun gear 4 radius and moving axis output wheel 2 radius also change thereupon, enlarging radius, and initiatively pivoted arm strengthens, and input torque increases, geometrical central axis (1), dead axle sun gear (4) are connected with ectosome.
Beneficial effect of the present invention is: novel form is unique, structure nature advantages of simple, and transmission performance is reliable and stable, and test proves: the obvious increase of input torque, and on the basis of other form structure transmission, transmission efficiency improves more than 5%.Better meet the active demand of all kinds of power machine energy-saving and emission-reduction, environmental protect.
Accompanying drawing illustrates: below in conjunction with Figure of description, the invention will be further described.
Fig. 1 is main schematic diagram of the present invention.
Fig. 2 is the left view of Fig. 1.
In Fig. 1-2, the geometrical central axis 1. overlapped, 2. moving axis output wheel, 3. moving axis sun gear, 4. dead axle sun gear, 5. duplex row of variables star-wheel, 6. duplex row of variables star-wheel axle center.
Embodiment: in the embodiment shown in fig. 1, moving axis sun gear 3 drives double-planetary gear 5 not only rotation but also revolve round the sun, and in revolution hour wheel, B wheel drive moving axis output wheel 2 rotates.Several new situation being different from the transmission of conventional planetary wheel is there is in rotation process.The first, duplex row of variables star-wheel 5 is directly installed on moving axis sun gear 3, and moving axis sun gear 3 instead of planet carrier.Second, due to the double-planetary gear that duplex row of variables star-wheel 5 is small one and large one, bull wheel is active pivoted arm, steamboat is passive pivoted arm, direction is revolved round the sun again together in Input Forces direction with planet wheel 5, so increase the active pivoted arm of planet wheel 5, namely in distortion lever duplex row of variables star-wheel 5, initiatively the arm of force is greater than by power arm, so input torque strengthens simultaneously.3rd, because duplex row of variables star-wheel 5 is arranged on moving axis sun gear 3, their angle speed is equal, illustrates that the therefore moving axis sun gear 3 of dead axle output wheel 2, moving axis output wheel 2 jiaos of speed are equal, but moving axis output wheel 2 linear speed is amid a sharp increase than the linear speed of moving axis sun gear 3, and moment of torsion strengthens thereupon.4th, do not changing moving axis sun gear 3 radius, namely the geometry axle center 1 of moving axis sun gear 3 is not changed under the prerequisite of duplex row of variables star-wheel 5 distance, strengthen planet wheel 3 radius, dead axle sun gear 4, moving axis output wheel 2 radius strengthen thereupon, the active pivoted arm of moving axis output wheel 2 also strengthens, and input torque strengthens simultaneously.In planet wheel 5, A wheel, the relatively past large of B wheel increase in addition, and add a large amount of, will determine according to system working space size, as then larger in boats and ships, train, heavy machinery etc., automobile, robot etc. are then relatively smaller.
In the embodiment shown in Figure 2, the B wheel of duplex row of variables star-wheel 5 is internal messing form with moving axis output wheel 2, also can take outer gearing form.In order to stability of rotation with reduce tooth and damage, planet wheel 3 is several symmetrical or evenly install at moving axis sun gear 3, because structure is identical, does not mark in this specification and Figure of description.
