Abstract
The utility model provides a planet wheel rolling friction transmission, includes sun gear of dead axle, two planets wheel and rocking arm, wherein the rolling friction transmission is carried out for the nos teeth of a cogwheel to the planet wheel, directly conduct input and output of rocking arm. This kind adopts K -2H type rolling friction planet wheel drive, has not only saved raw and other materials and the teeth of a cogwheel processing cost more than 40% 20% or more, and transmission efficiency obviously improves moreover, and simple structure is reasonable, and the stable performance is reliable, and the life extension is vibrated, the noise reduction, but the wide application in the gear drive of all kinds of machines, the better demand that satisfies energy saving and emission reduction, improves the environment.
Description
Technical field: this utility model relates to a kind of planetary gear train drive device, a kind of anodontia rolling friction planetary gear train drive device.
Background technology: at present, known planet circular system transmission uses 2K-H type, gear mesh form transmitting movement substantially, and gear teeth processing cost can not be saved, planetary gear and two sun gear engagements, raw material transmission cost can not reduce；Transmission efficiency can not improve.
Summary of the invention: in order to change the state of the art, this utility model uses the double-planetary gear of point size to substitute the setting of sun gear without gear teeth roll friction transmission technology and planet carrier, saves raw material and processing cost, improve transmission efficiency.Goal of the invention one is to reduce parts, reduction material, processing, transmission cost；Two is to strengthen 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, and the input point of the power of the time that determines the most instantaneous upper, space relative constancy and stress angle, by reducing parts, adjusting input and output angle speed, differential surface speed, it is achieved improve the purpose of transmission efficiency.
This utility model solves technical problem and be the technical scheme is that two pivoted arms and two planetary gears and dead axle sun gear 2 included in geometrical central axis 1, constitutes K-2H type, i.e. one sun gear, two pivoted arms and two planetary gears.The double-planetary gear 4 of point size installed by input pivoted arm 3, the bull wheel of double-planetary gear 4 engages with dead axle sun gear 2, steamboat is without the gear teeth and the output planetary wheel 6 implementation roll friction transmission on output pivoted arm 5, the steamboat of double-planetary gear 4 claims stress point 7 with the rolling friction point of output planetary wheel 6, stress point is referred to as stress angle with double-planetary gear 3 bull wheel by the angle in axle center 8 with dead axle sun gear 5 meshing point 9, 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.
This utility model provides the benefit that: novel form is unique, and simple and reasonable, transmission performance is reliable and stable, material, and processing cost is greatly reduced, and the life-span is long, noise, vibrates little, and detection test proves: transmission efficiency significantly improves.More preferably meet all kinds of power machine energy-saving and emission-reduction, improve the urgent needs of environment.
Accompanying drawing illustrates: below in conjunction with Figure of description, the utility model is described in further detail.
Fig. 1 is main schematic diagram of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is this utility model test figure
In Fig. 1-2,1. geometrical central axis, 2. dead axle sun gear, 3. input pivoted arm, 4. double-planetary gear, 5. output pivoted arm, 6. output planetary wheel, 7. stress point, the 8. axle center of double-planetary gear 4, the 9. bull wheel of double-planetary gear 4 and the meshing point of dead axle sun gear 2.
Detailed description of the invention: in the embodiment shown in fig. 1, the little wheel drive output planetary wheel 5 not only rotation of the double-planetary gear 4 on input pivoted arm 3 but also revolve round the sun, drive output pivoted arm 5 to rotate along operational forces direction during revolution.Owing to duplex row of variables star-wheel 4 is small one and large one double-planetary gear, bull wheel is active pivoted arm, and steamboat is passive pivoted arm, and therefore actively pivoted arm is more than passive pivoted arm, and operational forces direction is identical with revolution direction, so transmission efficiency improves.It addition, stress point 7 claims stress angle by the angle in double-planetary gear axle center 8 to double-planetary gear 4 with the meshing point 9 of dead axle sun gear 2, stress angle is in 0 ° to 90 ° interval；Owing to input pivoted arm 3 is by double-planetary gear 4 and output planetary wheel 6 driving output pivoted arm 5, so input pivoted arm 3 is consistent with the angle speed of output pivoted arm 5, but owing to two pivoted arm brachiums are inconsistent, so their linear speed is the most inconsistent, transmission efficiency also makes moderate progress.
In the embodiment shown in Figure 2, taking turns 6 positions for the output planetary after double-planetary gear 4 has shown, makes fine rule diagram on the right side of double-planetary gear 4.In order to stability of rotation damages with reducing tooth, double-planetary gear 4 and output planetary wheel 6 are several symmetrical with output pivoted arm 5 at input pivoted arm 3 or uniformly install, and owing to structure is identical, do not mark in this specification and Figure of description.
