Abstract
A kind of diameter differential teeth planetary wheel transmission device, duplex A, the B planetary gear including coaxial disjunctor, pivoted arm, fixed gear ring and sun gear etc., wherein duplex A planet wheel diameter is greater than the diameter of duplex B planetary gear and engages with dead axle gear ring, and duplex B planetary gear is engaged with sun gear.Test proves: this diameter has difference in size, the number of teeth to have the diameter differential teeth planetary wheel transmission device for more having few difference, and structure is simple, and novel form, transmission efficiency significantly improves.It can be widely applied in the gear drive of all kinds of machines, including the fields such as various traffic, metallurgy, mine, aviation, ship, national defence, water power, building industry, robot, agricultural machinery, more preferably meet energy-saving, the demand of enhancement of environment.
Description
Technical field: the utility model belongs to planetary gear train transmission field, and specifically a kind of diameter has difference in size, the number of teeth
There is the diameter differential teeth planetary Wheel train driving gear for more having the double-planetary gear of few difference as leading driving member.
Background technique: currently, the transmission of well known planetary gear train does not use diameter to have difference in size, the number of teeth to have few difference more
Double-planetary gear as leading driving member, do not nibbled using the big double-planetary gear of diameter as wheel for inputting and fixed gear ring
It closes, the small double-planetary gear of diameter and output sun gear engaged transmission form not can increase input torque, transmission efficiency cannot
It improves.
Summary of the invention: in order to change the state of the art, the utility model is had more using coaxial coenosarc, the number of teeth of diameter point size
There is few double-planetary gear as leading driving member, wherein the big double-planetary gear of diameter is engaged with fixed gear ring, and diameter is small
Double-planetary gear engaged with sun gear.Goal of the invention: increasing input torque, improves transmission efficiency.
Used technical solution is the utility model in order to solve the technical problem: diameter differential teeth planetary wheel transmission device, including
Input the sun gear 5 in the pivoted arm 1 in train, duplex A planetary gear 2, duplex B planetary gear 3, fixed gear ring 4 and output wheel train.Institute
The diameter for the duplex A planetary gear 2 stated is greater than the diameter of duplex B planetary gear 3, wherein duplex A planetary gear 2 is nibbled with fixed gear ring 4
It closes, duplex B planetary gear 3 and 5 external toothing of sun gear, the disjunctor coaxial with duplex B planetary gear 3 of duplex A planetary gear 2.
The beneficial effects of the utility model are: drive mechanism and driving form innovation, transmission efficiency significantly improve, test card
It is sensible to have arrived goal of the invention.
Detailed description of the invention: the utility model is described in further detail with reference to the accompanying drawings of the specification.
Fig. 1 is the main schematic diagram of the utility model.
Fig. 2 is the left view of the utility model.
In Fig. 1, Fig. 2,1. pivoted arms, 2. duplex A planetary gears, 3. duplex B planetary gears, 4. fixed gear rings, 5. sun gears.
Specific embodiment: Fig. 1, Fig. 2, shown in embodiment, input the pivoted arm 1 and input axis connection in train,
The big duplex A planetary gear 2 of diameter is engaged with fixed gear ring 4, and the small duplex B planetary gear 3 of diameter is engaged with sun gear 5, sun gear 5
It is connected with exporting axis, the disjunctor coaxial with duplex B planetary gear 3 of duplex A planetary gear 2, input shaft and output shaft are connect with ectosome, simultaneously
Two axis geometrical axis are overlapped.Work power drive pivoted arm 1 on input shaft rotates, and pivoted arm 1 drives duplex A, B planetary gear 2,3 to rotate,
Duplex B planetary gear 3 drives sun gear 5 to rotate, and realizes the speedup movement of entire diameter differential teeth planetary wheel transmission device.If too
Positive wheel 5 is used as wheel for inputting, and pivoted arm 1 is used as output, then, the big duplex A planetary gear 2 of diameter and sun gear external toothing, diameter are small
Duplex B planetary gear 3 engaged with fixed gear ring, realize the retarded motion of entire diameter differential teeth planetary wheel transmission device.
The utility model core technology is: diameter has difference in size, the number of teeth to have the double-planetary gear conduct for more having few difference
The structure setting of leading driving member, the big duplex A planetary gear train of diameter is as input, small 3 conduct of duplex B planetary gear of diameter
Output, and duplex A, B planetary gear 2,3 is coaxial disjunctor, according to lever principle (because duplex A, B planetary gear 2,3 is deformation thick stick
Bar), input pivoted arm is big, and output pivoted arm reduces, and increases input torque, realizes the raising of transmission efficiency.In addition, in planetary gear
It is transmission ratio formula: n1-nH/n3-nH=-Z3/Z1In (wherein n3For dead axle sun wheel speed, n1Moving axis sun wheel speed, nHTurn
Arm revolving speed, Z3The dead axle sun gear number of teeth, Z1The moving axis sun gear number of teeth ,-turn to), due to must be the size of speed revolution value together with it
Symbol substitute into formula operation, transmission ratio final calculation result are as follows: 1+Z together3/Z1, 1 is a constant, and planetary gear is not involved in transmission ratio
It calculates, so, planetary gear changes in any case, influences on gear ratio calculation and little, in the case of this is for conventional gear ratio, mentions
High input torque is still ideal chose.
For uniform force and stability of rotation, duplex A, B planetary gear 2,3 is several symmetrical or uniformly installation together with pivoted arm 1.
