Description
The present invention is a kind of stars transmission device.
Many shortcomings such as at present, the use of dead tooth transmission is still quite general, and that this transmission device exists is bulky, cost is high, efficient is low are conspicuous.The second generation transmission device that the eighties occurs has Oscillating Tooth Gear Reducer, as CN85200606; The ripple swing is moving, as CN87216355.5 etc., all belongs to the engagement of skid curve conjugate profiles, and they need be with expensive dedicated gear machine tool production large volume, inefficient tooth gear, and shortcoming is still more obvious.
The objective of the invention is to avoid above-mentioned existing in prior technology deficiency, and provide that a kind of volume spy is little, cost special low, bearing capacity is big, speed ratio is especially big, meshing efficiency is high, the stars transmission device of long service life.
Purpose of the present invention can reach by following measure:
Principle of the present invention is that the driving link between arbitrary axis promotes the star tooth, along giving the pure rolling instantaneous Center conjugation engagement that the phase track drives the driven member transmission.The star tooth had both been made transmission component, and supporting member rotates again.Quicken or the retarder track as long as the star tooth is designed, located and relative fixed, just can realize the multi-freedom degree operation, the stars motion in celestial body.
A kind of planetary speed reducer, have driven member 6 and driving link 1, one termination motor of driving link 1, its special way is: the other end of described driving link 1 is provided with the star toothholder, star tooth 2 is located on the star toothholder, be located on the planet carrier 12 with the star tooth 3 of star tooth 2 engagements, be located on the planet carrier 13 with the star tooth 4 of star tooth 3 engagements, described star tooth 2, one side of star tooth 3 and star tooth 4 is by sound rail 9 positioning and fixing, its opposite side is by quiet rail 8 positioning and fixing, be arranged in the rotating disk of driven member 6 with the star tooth 5 of star tooth 4 engagements, it is 15 that frame 14 is provided with oil duct, and described driving link 1 is provided with pressure pump 16.
Moving rail 11, moving rail 10 and moving rail 7 can be set respectively between star tooth 2 of the present invention and star tooth 3, star tooth 3 and star tooth 4, star tooth 4 and the star tooth 5.
The accompanying drawing drawing is described as follows:
Fig. 1 is a side-looking structural drawing of the present invention.
Fig. 2 faces structural drawing for the present invention.
Below in conjunction with accompanying drawing the present invention is elaborated:
Referring to Fig. 1, an end and the motor of driving link 1 are affixed, and the other end is the star toothholder, with star tooth 2 people's seats.Instantaneous pair of making pure rolling of being meshed with star tooth 2 is star tooth 3, and star tooth 3 is installed on the planet carrier 12 with annular seating, is installed on the planet carrier 13 with the star tooth 4 of star tooth 3 engagements.One side of star tooth 2, star tooth 3 and star tooth 4 is all done the location with fixing by sound rail 9, and its opposite side is all by quiet rail 8 positioning and fixing.Be installed in the rotating disk of driven member 6 with the star tooth 5 of star tooth 4 engagements.When if star tooth 2 does not join owing to conjugate profiles with star tooth 5 with star tooth 4, star tooth 4 with star tooth 3, star tooth 3, for keeping each star tooth pure rolling, can between star tooth 2 and star tooth 3, lay moving rail 11, between star tooth 3 and star tooth 4, lay moving rail 10, lay moving rail 7 between star tooth 1 and star tooth 5, the shape of moving rail can be a cylinder bodily form shape etc. by star tooth Design Theory.The star tooth is the no-load element, and it is a driving component, is again rotatable support.For keeping the pure rolling film lubrication, offer wind-tunnel and oil pressure fluidic networks on the frame 14, promptly oil duct is 15, the pressure pump 16 supply oil ducts that are installed on the driving link 1 are 15 high-pressure sprays, directly are emitted to all contact pointss, generate vortex power system and levitating field, to support external load, load in the balance.When driving link 1 promotes star tooth 2, will drive star tooth 3, star tooth 3 drives star tooth 4, and star tooth 4 drives star tooth 5, and star tooth 5 will drive driven member 6 constant speed transmissions.Driving link 1 and driven member 6 are done the transmission of coaxial or different axis.Star tooth 3 and star tooth 4 are installed in respectively in planet carrier 12 and the planet carrier 13, do planetary motion along dynamic and static track separately, constitute planet accelerator or retarder, produce the huge vortex field of force.Each star tooth is instantaneous does rotation and revolution, as long as given active star tooth, according to mesh theory just can comprehensive driven star tooth conjugation pure rolling flank profil, can obtain many kinds of star flank profils.With embodiment illustrated in fig. 1 is example: with motor driving driving link 1, the other end of driving link 1 is provided with the star toothholder, design 99 seats, the star tooth 2 people's seats with 99 bielliptic(al)s constitute are installed in 100 star teeth 3 that are meshed with star tooth 2 in the planet carrier 12 with annular seating.Referring to Fig. 2, because compile apart from being 0102 with the center 02 of planet carrier 12 at the center 01 of driving link 1, obtaining a gear-stage velocity ratio is 100; Star tooth 3 is meshed with 101 star teeth 4, and its offset distance is 0203, and obtaining two gear-stage velocity ratios is 101; Star tooth 4 is meshed with 101 star teeth 5, installs with one heart, drives driven member 6 by the operation of 10100 speed ratios.When as shown in Figure 1 fixed with prime mover of driving link 1, promptly driven member 6 is made driven member, then obtains gearing down, and speed ratio is 10100; If driven member shown in Figure 16 and prime mover is fixed, promptly driven member 6 is done driving link, then obtains to drive up.
The present invention compared with prior art has following advantage:
1, the star tooth is the no-load element, and described transmitted power and component size are irrelevant, so bearing capacity is very big. Transmitted power is 10-2～10
4KW。
2, meshing efficiency extra-high-speed, meshing efficiency is higher than 90%～99%.
3, cost is very low. Because the part with interchangeability, versatility of standardization, normalization, seriation can be produced, be designed and manufactured into to element in a large number, direct-assembling becomes various stars transmission devices, so integrated cost is very low.
4, service life is very long. Because element can be made to the element of high rigidity, high accuracy, high efficiency, high life, greatly prolong service life.
5, simple in structure, volume is little.Volume only is 1%～50% of a tooth worm gear pairs.
6, speed ratio is 1～10
5, distance between shafts is 5～10
4Mm.
7, be specially adapted to the various accelerating transmission gears that subtract of high speed, heavy duty, precision, high speed ratio.
