Second level diameter differential teeth planetary wheel drive mechanism, including pivoted arm, A, B planetary gear, fixed gear ring in the sun gear and input train in output wheel train.A, B planetary gear is all small one and large one double-planetary gear of diameter, while being all mounted on pivoted arm, and big double-planetary gear is as wheel for inputting, and minor diameter double-planetary gear is as output wheel.This diameter is variant, the number of teeth has the second level duplex planet wheel drive mechanism for more having few difference, hence it is evident that increases input torque, improves transmission efficiency.It can be widely applied in the machine driving in the fields such as traffic, metallurgy, national defence, mine, light textile, water power, robot, building industry, machine tool, agricultural machinery, more preferably meet energy-saving, the demand of enhancement of environment.
Description
Technical field: specifically a kind of that two planetary gears are installed on pivoted arm the invention belongs to planetary gear train transmission field
And two planet wheel diameters are all to have difference in size, the number of teeth to have to have the double-planetary gear of few difference as leading driving member more
Second level diameter differential teeth planetary wheel wheel drive mechanism.
Background technique: currently, well known 2K-H type planetary gear train is driven, planetary gear is not leading driving member, is not adopted
It is all the double structure of diameter point size, Bu Nengshi with the planetary gear and two planetary gears of installing two coaxial one on pivoted arm
The secondary increase of existing input torque, is not achieved the maximization of input torque, transmission efficiency cannot significantly improve.
Summary of the invention: in order to change the state of the art, the present invention divides size using installation two coaxial coenosarcs, diameters on pivoted arm
Difference, the number of teeth have and have the double-planetary gear of few difference as leading driving member more, and wherein diameter is big, the duplex sun more than the number of teeth
Wheel is used as wheel for inputting, and the double-planetary gear wheel that diameter is small, the number of teeth is few is as output wheel.Goal of the invention: increasing input torque, improves
Transmission efficiency.
The technical scheme adopted by present invention for solving the technical problem is that second level diameter differential teeth planetary wheel drive mechanism, including
Sun gear 1, output shaft 2 in output wheel train and the input shaft 3 in input train, A planetary gear 5, B planetary gear 6, are consolidated pivoted arm 4
Fixed tooth circle 7, it is characterized in that: the A planetary gear 5 and B planetary gear 6 is all mounted on pivoted arm 4, the A planetary gear 5 and B row
Star-wheel 6 be all coaxial one, diameter small one and large one, the few double-planetary gear of the number of teeth more than one one, wherein A planetary gear 5 it is small straight
The few double-planetary gear of diameter, the number of teeth is engaged with sun gear 1, and the double-planetary gear more than major diameter, the number of teeth is small straight with B planetary gear 6
The few double-planetary gear engagement of diameter, the number of teeth, the double-planetary gear more than the major diameter of B planetary gear 6, the number of teeth are engaged with fixed gear ring 7.
The beneficial effects of the present invention are: drive mechanism and driving form are innovated, under conventional gear ratio, transmission efficiency is obviously mentioned
Height, test prove to have reached goal of the invention.
Detailed description of the invention: the invention is further explained in the following combination with the attached drawings of the specification.
Fig. 1 is main schematic diagram of the invention.
Fig. 2 is left view of the invention.
In Fig. 1, Fig. 2,1. sun gears, 2. input shafts, 3. output shafts, 4. pivoted arms, 5.A planetary gear, 6.B planetary gear, 7.
Fixed gear ring.
Specific embodiment: Fig. 1, Fig. 2, shown in embodiment, pivoted arm 4 passes through the work power drive B row of input shaft 3
The big double-planetary gear of star-wheel 6 is engaged with fixed gear ring 7, and B planetary gear 6 rotates, the small double-planetary gear and A planet of B planetary gear 6
The big double-planetary gear engagement of wheel 5, A planetary gear 5 rotate, and the small double-planetary gear of A planetary gear 5 is engaged with sun gear 1, sun gear
1 and output shaft 2 rotate, realize entire second level diameter differential teeth planetary wheel drive mechanism speedup movement；If input shaft 2, the sun
Wheel 1 becomes exporting as input train, pivoted arm 4 and input shaft 3, then, the major diameter double-planetary gear and the sun of A planetary gear 5
6 engagement of wheel, minor diameter double-planetary gear are engaged with the major diameter double-planetary gear of B planetary gear 6, the minor diameter duplex of B planetary gear 6
Planetary gear is engaged with fixed gear ring 7, realizes the retarded motion of entire second level diameter differential teeth planetary wheel drive mechanism.
Core technology of the present invention is: two large and small A, B duplexs of (or more than two) diameter point are installed on a pivoted arm 4
The structure setting of planetary gear 5,6, this structure setting increase input torque, improve power in conventional gear ratio
Transmission capacity, this is because: firstly, wheel more than the major diameter number of teeth, input, the few wheel of minor diameter, the number of teeth is as output, this itself
Increase input torque.Although secondly, planetary gear 5,6 all be deformation lever, stress situation is different, if only
The meshing point of one B planetary gear, (when step-up drive) major diameter double-planetary gear and fixed gear ring 7 is instantaneous fulcrum, and fulcrum arrives
The distance (large radius) in axle center is power arm, and large radius adds the distance of minor radius to be resistance arm, it is clear that resistance arm is greater than power arm；
If installing an A planetary gear again, A planetary axle center is fulcrum, and major diameter double-planetary gear radius is power arm, and minor diameter is double
Joining planetary gear radius is resistance arm, it is clear that resistance arm is less than power arm, realizes the secondary increase of input torque, therefore, can be with
The double-planetary gear of multiple 5 this spline structure of A double-planetary gear is installed.In addition, in Transmission Ratio of Planetary Gear Trains formula: n1-nH/n3-nH
=-Z3/Z1In (wherein n3Dead axle sun wheel speed, n1Moving axis sun wheel speed, nHPivoted arm revolving speed, Z3The dead axle sun gear number of teeth, Z1
The moving axis sun gear number of teeth ,-turn to), due to that the size of speed revolution value must be substituted into formula operation, institute together with its symbol together
With transmission ratio final calculation result are as follows: 1+Z3/Z1, 1 is constant, and planetary gear is not involved in gear ratio calculation, so, planetary gear without
By how to change, gear ratio calculation result is influenced and little, in the case of this is for conventional gear ratio, improves input torque still
It is ideal chose.
For uniform force and stability of rotation, pivoted arm 4 and planetary gear 5,6 are several symmetrical or uniformly installation.
