The utility model has the advantages that: it is laborsaving to economize merit, the energy utilization ratio height.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.Accompanying drawing 2,3,4 is the utility model fundamental diagram.
Embodiment
As shown in Figure 1, central shaft 10 is fixed on the support 11, planet carrier 4 rotates around central shaft 10, sun gear 1 is fixed on the central shaft 10, planet wheel 2 shaft types are movably connected on the planet carrier 4, the internal diameter of transmission ring 3 with install wheel additional and 7 be meshed, the internal diameter of transmission ring 3 is meshed with center pulley 12, secondary planet wheel 5 shaft types are movably connected on the planet carrier 4, secondary planet wheel 5 is meshed with transmission ring 3, ratchet 8 is installed on the secondary planet wheel 5, and power output wheel 9 is movably arranged on the central shaft 10, and ratchet 8 links to each other by chain 6 transmissions with power output wheel 9.
Working principle:
See Fig. 2, when the power with F moved in the direction of the clock transmission ring 3, planet wheel 2 drove planet carrier 4, move in the direction of the clock simultaneously, the suffered power in the axle center of planet wheel 2 is 2F, establishes sun gear 1 and the even r of being of the radius of planet wheel 2, and the power that planet carrier 4 is subjected in the 4r place is F.
But the device of Fig. 2 can not be economized merit.
How just can make its device reach the order ground of province's merit?
Can transmission transmission ring 3 when can we it is contemplated that the power that apply F, drive planet wheel 2 and move in the direction of the clock, produce another power simultaneously and can hinder planet carrier 4 rotations again, equal and opposite in direction, the direction of its power are opposite, make planet carrier 4 be in stress balance, and produce displacement again and do work.
See Fig. 3
Suppose that (this place is called equinoctial point at the 4r place on the left side of planet carrier 4 (is reference point with the central axis) for we, as follows) the secondary planet wheel 5 isometrical with sun gear 1 be installed, when installing the power of chain on the secondary planet wheel 5 additional and spur secondary planet wheel 5 along Fig. 3 direction F, secondary planet wheel 5 drives planet wheel 2 by transmission ring 3 and rotates, make the power of the right generation 2F of planet carrier 4, direction is clockwise.The axle center (left side) of secondary planet wheel 5 produces the power of F simultaneously, and direction is counterclockwise.This all is isometrical because of sun gear 1, planet wheel 2, secondary planet wheel 5.Secondary planet wheel 5 is installed on the equinoctial point on the left side, and planet carrier 4 is a run-on point with the axle center, and establishing tooth radius is then F4r=2F2r of r, and planet carrier 4 suffered power are in balance.F in this formula can be an arbitrary value, that is to say no matter apply great load force F on chain, and planet carrier 4 suffered power all are in balance, rotates the required power of planet carrier so and only equals the frictional force between the gear and the resistance of air.
Though 4 suffered power have reached balance but the action effect of Fig. 3 makes planet carrier, still do not have displacement.
How just can make not only stress balance but also produce displacement of planet carrier 4?
See Fig. 4
If we the position of transmission ring 3 to right translation once, mounting center pulley 12 on central shaft 10, the radial design of center pulley 12 less, the distance of the axle center of so secondary planet wheel 5 (equinoctial point) in the relative Fig. 3 with the distance of the engagement place of transmission ring 3 of secondary planet wheel 5, just the radius than planet wheel 2 is big for the radius of secondary planet wheel 5 among Fig. 4.The engagement internal diameter, secondary planet wheel 5 of supposing planet wheel 2 and transmission ring 3 and transmission ring 3 corresponding engagement external diameters equate.When the force level with F drew secondary planet wheel 5, secondary planet wheel 5 made planet carrier 4 that the trend that moves in the direction of the clock be arranged by transmission ring 3 band planet wheels 2, and secondary planet wheel 5 produces an anticlockwise power again simultaneously, makes planet carrier 4 be in balance.Otherwise so, when rotating planet carrier 4, planet wheel 2 circles, and secondary planet wheel 5 revolutions produce displacement less than a week and do work.
The radius of center pulley 12 is changeable, does not have causality with the stress balance of planet carrier 4.The displacement that pulley 12 more little its devices in center are produced is big more.
Transmission ring 3 only plays gearing in device, the relative transmission position phase shift of transmission ring 3 and planet wheel 2, secondary planet wheel 5 etc., and its institute is stressed also to be equated.Should be in design planet wheel 2, secondary planet wheel 5, center pulley 12, transmission ring 3 processing precises, because transmission ring 3 does not have central shaft, central shaft is installed in any position, its device is not economized merit.It with central shaft 10 for stirring a little.Can be designed to crescent shape to center pulley 12, make its surface of contact big.Help the rotation of transmission ring 3 like this.
The position of secondary planet wheel 5 also can be installed in the right among Fig. 4, secondary planet wheel 5 is meshed with the external diameter of transmission ring 3, that designs between the internal diameter of transmission ring 3 and the external diameter is thicker, the shaft core position of secondary planet wheel 5 is at the 4r place, the radius of so secondary planet wheel 5 is programmable than little many of the radius of planet wheel 2, makes them have individual difference to realize displacement in transmission.
