Abstract
A kind of planetary gear roll friction transmission device, including one sun gear of dead axle, two planetary gears and pivoted arm, wherein planetary gear are, without the gear teeth, to carry out roll friction transmission, and pivoted arm is directly as input and exports.This use K-2H types rolling friction planetary gear transmission device, not only save more than 20% raw material and more than 40% gear teeth processing cost, and transmission efficiency is significantly improved, it is simple and reasonable, it is stable and reliable for performance, service life extension, vibration, lower noise, can be widely applied in the gear drive of all kinds of machines, better meet energy-saving and emission-reduction, improve the demand of environment.
Description
Technical field：The present invention relates to a kind of planetary gear train drive device, specifically a kind of anodontia rolling friction
Planetary gear train drive device.
Background technology：At present, known planet circular system transmission is basic uses 2K-H types, gear mesh form to pass
Motion is passed, gear teeth processing cost can not be saved, planetary gear is engaged with two sun gears, raw material transmission cost
Can not reduce；Transmission efficiency can not be improved.
The content of the invention：In order to change the state of the art, the present invention is rolled using the double-planetary gear of point size without the gear teeth
Dynamic friction drive technology and planet carrier substitute the setting of sun gear, save raw material and processing cost,
Improve transmission efficiency.Goal of the invention one is to reduce part, reduce material, processing, transmission cost；Two is to add
Big input torque, saves energy consumption, improves transmission efficiency；Three is to increase the service life, reduce noise and vibration.
It is, according to planetary gear characteristic and mechanics principle, to determine the time upper instantaneous, input of the power of space relative constancy
Point and stress angle, by reducing part, adjustment input and output angle speed, differential surface speed, realize improving transmission effect
The purpose of rate.
The technical proposal for solving the technical problem of the invention is：Turn including two in geometrical central axis 1
Arm and two planetary gears and dead axle sun gear 2, constitute the sun gear of K-2H types, i.e., and two turn
Arm and two planetary gears.Input pivoted arm 3 installs the double-planetary gear 4 of point size, double-planetary gear 4
Bull wheel engaged with dead axle sun gear 2, steamboat without the gear teeth with output pivoted arm 5 on output planetary wheel 6
Roll friction transmission is carried out, the steamboat of double-planetary gear 4 claims to receive with the rolling friction point of output planetary wheel 6
Force 7, stress point is with the bull wheel of double-planetary gear 3 by axle center 8 and the meshing point 9 of dead axle sun gear 5
Angle be referred to as stress angle, stress angle is more than 0 °, less than 180 °.Input pivoted arm 3 and output pivoted arm
5 dock with engine and working machine respectively.
Present invention has the advantages that：Novel form is unique, and simple and reasonable, transmission performance is reliable and stable,
Material, processing cost is greatly reduced, long lifespan, and noise, vibration are small, and detection experiment is proved：Transmission efficiency
Significantly improve.More preferably meet all kinds of power machine energy-saving and emission-reduction, improve the active demand of environment.
Brief description of the drawings：With reference to Figure of description, the invention will be further described.
Fig. 1 is main schematic diagram of the invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is test chart of the present invention
In Fig. 1-2,1. geometrical central axis, 2. dead axle sun gear, is 3. input into pivoted arm, 4. double-planetary gear,
5. pivoted arm is exported, 6. output planetary wheel, 7. stress point, 8. the axle center of double-planetary gear 4,9. duplex row
The bull wheel of star-wheel 4 and the meshing point of dead axle sun gear 2.
Specific embodiment：In the embodiment shown in fig. 1, the double-planetary gear 4 being input on pivoted arm 3
Not only rotation but also the revolution of small wheel drive output planetary wheel 5, drives output pivoted arm 5 to turn along work force direction during revolution
It is dynamic.Because duplex variable planetary gear 4 is small one and large one double-planetary gear, bull wheel is active pivoted arm, steamboat
It is passive pivoted arm, therefore active pivoted arm is more than passive pivoted arm, and the force direction that works is identical with revolution direction, institute
Improved with transmission efficiency.In addition, stress point 7 is arrived double-planetary gear 4 and is determined by double-planetary gear axle center 8
The angle of the meshing point 9 of axle sun gear 2 claims stress angle, and stress angle is in 0 ° to 90 ° interval；Due to input
Pivoted arm 3 drives output pivoted arm 5 by double-planetary gear 4 and output planetary wheel 6, so input pivoted arm 3 and defeated
The angle speed for going out pivoted arm 5 is consistent, but because two pivoted arm brachiums are inconsistent, so their linear speed also differs
Cause, transmission efficiency also makes moderate progress.
In the embodiment shown in Figure 2, for the position of output planetary wheel 6 after double-planetary gear 4
It has been shown that, fine rule diagram is made on the right side of double-planetary gear 4.In order to stability of rotation and reduction tooth are damaged, duplex row
Star-wheel 4 and output planetary wheel 6 be it is several input pivoted arm 3 and output pivoted arm 5 it is symmetrical or it is uniform install, by
It is identical in structure, do not marked in this specification and Figure of description.
