Power transfer path one：Power is transferred to input gear, input gear by input shaft (power source) by input shaft
The revolving force of input is transferred to the internal tooth of gear ring.The revolving force for being transferred to gear ring internal tooth rotates the multiple engaged with gear ring internal tooth
On planetary gear, planetary gear is set to be rotated around the wheel shaft of itself.Input to planetary revolving force by with multiple rows
The central gear of star gear engagement passes to output shaft, completes power transfer path one.In the path, power source input is defeated
Enter the number of teeth, the inside and outside number of teeth of gear ring, the planetary number of teeth, the adjustment of the central gear number of teeth of gear, be the rotation of output shaft
Power can be increased or decreased or constant key, i.e., by adjusting the gear ratio of above-mentioned five kinds of gears, obtain output shaft revolving force

Principle is：Pass through the path using same input shaft (i.e. same power source), impart power to planet carrier
Gear.Input shaft-speed increasing gear-idler gear-planet carrier gear.The revolving force of speed increasing gear is passed to again by centre
Gear drives planet carrier gear rotation.The revolving force of planet carrier gear is transferred on each planetary wheel shaft by planet carrier,
Multiple planetary gears are driven to be revolved round the sun around central gear along gear ring internal tooth.The direction of rotation of planet carrier and the direction of rotation of gear ring internal tooth
Conversely, when opposite direction is rotated, according to gear ring internal tooth and the ratio of central gear, output speed is increased, so as to increase output shaft
Rotation speed.When the number of teeth 10T=planet carriers of the number of teeth 100T ÷ central gears of gear ring internal tooth rotate a circle, planetary gear revolution one
Circle, output shaft increases by 11 and encloses.The revolving force that planetary gear is produced when rotating passes to central gear, with power transfer path one
Rotation speed can increase the rotation speed of output shaft after combining.In this process, by adjusting the number of teeth and planet carrier tooth of speed increasing gear
The number of teeth of wheel carrys out the rotation speed of motivation of adjustment source input, makes the rotation speed of output shaft and increases.
When need input shaft direction of rotation it is identical with the direction of rotation of output shaft when, in power transfer path 2

When opposite, input gear and gear ring the external tooth link in idler gear and power transfer path 1.
As shown in Figure 5：A kind of planetary gear speeder of many playscript with stage directions applications can be used in series, such that it is able to obtain multistage
Rotation speed, the increased power transfer path of revolving force.A kind of more than 2 (plural number) planetary gear speeder is entered into action edge connection
Connect, obtain the output characteristic of larger rotation speed and revolving force.
The revolving force of input shaft rotates gear ring by input gear, makes the multiple planet gear drives engaged with gear ring internal tooth
Central gear is rotated, so that the revolving force of input shaft passes to output shaft.Or revolving force from same input shaft and
Rotation speed, planet carrier is passed to by planet carrier gear, and revolving force and rotation speed from input shaft connect by with planet carrier again
The wheel shaft for connecing passes to planetary gear, and each planetary gear is rotated in the opposite mode in gear ring direction of rotation along gear ring internal tooth, so that
Increase the rotation speed of central gear, the revolving force and rotation speed of power transfer path 1 pass to output shaft, can increase output shaft
Revolving force and rotation speed.After described power transfer path one and the power of power transfer path two converge, by increasing capacitance it is possible to increase output
The rotation speed and revolving force of axle.Gear ring direction of rotation is opposite with the direction of rotation of planet carrier to increase rotation speed, so as to increase defeated
The rotation speed of shaft.
Original planetary gear speeder or decelerator be planetary gear in fixed carrier along gear ring internal tooth rotation,
By the revolving force of input shaft and rotation speed pass to central gear, finally by output shaft export structure, be a kind of revolving force and
Rotation speed is in the power set of inverse ratio.The application drives planet carrier to rotate together with by a power source input shaft, makes each planet
Gear revolves round the sun along central gear, and the direction of rotation of each planetary revolution direction and gear ring is conversely, each planetary rotation
Direction is identical with the direction of rotation of gear ring, as shown in Figure 22 to Figure 24, according to active force 21 and the principle of reaction force 22, tooth
When circle internal tooth is around planetary gear rotation, planetary gear produces a reaction force, now, planet can be driven with less power
Frame is inverted, so as to obtain the technique effect for increasing rotation speed, thus produces gear ring to increase with the tooth ratio of central gear, rotation
Power is increased.So that rotation speed and revolving force increase simultaneously.
The revolving force increase of output shaft is produced by power transfer path one.The rotation speed of output shaft increases transmits road by power
Footpath two produces.Can also can realize increasing by 2 times of output shaft rotation speed under conditions of input shaft revolving force is not increased, and not
Also the revolving force of output shaft can be increased in the case of increasing input shaft rotation speed.
In conventional art：When the revolving force of input shaft is 100Nm, when rotation speed is for 1000rpm, the rotation speed of output shaft is
The rotation speed of 2 times, i.e. output shaft is 2000rpm, and revolving force is 1/2 i.e. 50Nm.The present invention is a kind of revolving force and rotation speed point
