Description
One, technical field: the present invention relates to a kind of mechanical variable speed drive, especially relevant with planetary transmission.
Two, background technique: planetary transmission, since appearance, for the design of speed changer and operation etc. provide a great convenience, has been widely used in various speed change gear so far.But because the composition of planetary transmission is comparatively complicated, there is again higher required precision, usually the cost higher than general gear pair is had, therefore planetary gear speed-changing function should be had for some, structure is simple again, can realize the place (as electric bicycle uses) that low cost manufactures, planetary transmission just loses the market competitiveness.
Three, summary of the invention: task of the present invention be to provide a kind of can with planetary transmission equivalence and there is simple, the cheap speed changer of structure.
In order to solve above-mentioned task, solution of the present invention is, replaces the gear transmission in planetary transmission with relatively inexpensive sprocket driving whole or in part.
First be all replace gear transmission with sprocket wheel, the sun gear in original planetary transmission is become a sprocket wheel, the present invention is called main chain wheel; Ring gear is turned into another sprocket wheel, the present invention is called time sprocket wheel; Main chain wheel and time sprocket wheel are arranged on respectively to be had on the axially different position of the out-of-alignment of identical rotating center with planet carrier; Change the planetary pinion on planet carrier into two sprocket wheels again, the present invention is called primary planet sprocket wheel and time planet sprocket respectively, primary planet sprocket wheel and time planet sprocket can be installed on the axially different position of the same rotating shaft (this rotating shaft is called planet axis by the present invention) of installing on planet carrier synchronous rotary, and make the axial position of primary planet sprocket wheel and time planet sprocket, be right against main chain wheel and time sprocket wheel installation respectively; Finally main chain wheel is connected with primary planet sprocket wheel chain, secondary sprocket wheel is also connected with chain with time planet sprocket.This is planetary gear derailleur of the present invention, it and traditional planetary transmission have similar shifting characteristics: if allow these three elements of main chain wheel, secondary sprocket wheel and planet carrier (allly have " three elements " printed words later, namely main chain wheel, secondary sprocket wheel and planet carrier is referred to) all unfettered, namely can freely rotate, then this planetary gear derailleur loses gearing completely; If allow any two in these three elements and to make another element maintain static respectively as driving link and driven member, then this planetary gear derailleur is with certain gear ratio transferring power; If make can not relatively rotate between any two in these three elements, all can not relatively rotate between three elements then in this planetary gear derailleur, being equivalent to define direct high transmission (has a special case to illustrate here, when velocity ratio between main chain wheel and primary planet sprocket wheel equals secondary velocity ratio between sprocket wheel and secondary planet sprocket, although main chain wheel can not relatively rotate with time sprocket wheel, planet carrier still can freely rotate.Certainly this is also a part of the present invention, and it is not only by main chain wheel and time sprocket wheel shaft coupling, and planet carrier is still free to rotate).
Because planetary gear derailleur of the present invention is sprocket driving, planetary transmission therefore can be made up because of the narrow limitation of gear transmission in sense of rotation.But, sprocket driving in fact also can resemble gear transmission carries out reversing drive: outside the chain carrying out chaindriven two sprocket wheel neutral positions, newly installation one and the sprocket wheel engaged outside chain again, so this is newly installed on the sense of rotation of the sprocket wheel outside chain and the direction of rotation of original two sprocket wheels, and this just constitutes the reversing drive of sprocket wheel.This reversing drive mode of sprocket wheel is called anti-chain transmission by the present invention.If allow between main chain wheel and primary planet sprocket wheel and adopt anti-chain transmission, and between secondary sprocket wheel and secondary planet sprocket, still adopt the original kind of drive (if also adopt anti-chain transmission, the present invention can certainly be implemented, this also belongs to protection scope of the present invention, just there is no special requirement, generally can not adopt two anti-chain transmissions, therefore the present invention does not do too much discussion to this yet), so also the present invention can be implemented completely, therefore the present invention adopts anti-chaindriven planetary gear derailleur to be called anti-chain formula planetary gear derailleur by this between main chain wheel and primary planet sprocket wheel or between secondary sprocket wheel and secondary planet sprocket.Because the sense of rotation of the primary planet sprocket wheel in this anti-chain formula planetary gear derailleur there occurs change, the sense of rotation between wherein three elements and original different will be caused, numerically (" numerically " represents it is digital value own to velocity ratio such as between main chain wheel and primary planet sprocket wheel, have nothing to do with the sign of numeral, be equivalent to absolute value, below all with, no longer repeat) when equaling velocity ratio with time planet sprocket of time sprocket wheel, this anti-chain formula planetary gear derailleur of the present invention, be provided with the function of differential mechanism, a differential mechanism can be become, its input end is planet carrier, planet carrier can be made a sprocket wheel, direct chain carries out transmission, two output terminals are main chain wheel and time sprocket wheel respectively.
Next in above-mentioned planetary gear derailleur, partly replaces sprocket wheel with gear carry out transmission (this with partly replace with sprocket wheel the reason that gear carries out transmission in planetary transmission be consistent), at main chain wheel and primary planet sprocket wheel or between secondary sprocket wheel and secondary planet sprocket, optional a pair, make it be turned into gear transmission.The present invention replaces transmission for main chain wheel and primary planet sprocket wheel gear here, main chain wheel is turned into master gear, primary planet sprocket wheel is turned into main planetary gear, and makes master gear and main planetary gear engagement.This is a gear transmission and sprocket driving planetary gear derailleur used in combination.The present invention is called gear type planetary gear derailleur.Obviously it is the same that the geared portions in this gear type planetary gear derailleur carries out anti-chaindriven sense of rotation with sprocket wheel above, therefore when the velocity ratio similarly between master gear and main planetary gear is numerically equal to secondary velocity ratio between sprocket wheel and secondary planet sprocket, this gear type planetary gear derailleur, also a differential mechanism can be become, its input end is planet carrier, and two output terminals are master gear and time sprocket wheel.
These above-mentioned two kinds of differential mechanisms, because inside does not have axial force, therefore structure is comparatively simple, volume is also less, and cost easy to manufacture is low, is the first-selected product of low cost running mechanism.
In sum, planetary gear derailleur of the present invention, not only there is the function similar with planetary transmission, and the superiority having planetary transmission incomparable in cost, to be particularly applied on common chaindriven vehicle (as on electric bicycle or tricycle. even speed changer is installed on wheel hub first-class) will its use value more aobvious.But except the advantage in price, because sprocket driving and gear transmission have contrary sense of rotation, therefore, planetary gear derailleur of the present invention, can make up the single and deficiency caused in direction because of the transmission of planetary pinion middle gear.In addition, the present invention also can carry out anti-chain transmission or toothed chain mixed drive, to widen the design space of speed changer further, can also make simple, the cheap differential mechanism of structure simultaneously, this differential mechanism not necessarily wants transmission shaft driven, can act on the sprocket wheel be made up of planet carrier by direct chain.Therefore the present invention has Practical significance.

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Five, embodiment:
Fig. 1 is the structure and working principle schematic diagram of planetary gear derailleur
In figure, main chain wheel 1 and time sprocket wheel 2 are that to be installed on same central shaft system 8 (be the rotating center of main chain wheel, secondary sprocket wheel and planet carrier here, three axles can be had to exist, therefore the present invention is called " central shaft system 8 ") on two sprocket wheels on axially different position, these two sprocket wheels all can rotate freely around central shaft system 8 separately, planet carrier 3 is installed in central shaft system 8, also freely can rotate around central shaft system 8, planet carrier 3 is also provided with planet axis 9, planet axis 9 is provided with primary planet sprocket wheel 4 with time planet sprocket 5 (because the reason of structure, here planet sprocket must link main chain wheel 1 and time sprocket wheel 2 simultaneously, therefore planet sprocket is the sprocket wheel on two axially different positions being installed in same planet axis 9, in order to the convenience illustrated, the present invention is distinguished called after primary planet sprocket wheel 4 and time planet sprocket 5), primary planet sprocket wheel 4 in figure has been drawn in the back side of secondary planet sprocket 5, primary planet sprocket wheel 4 and time planet sprocket 5 can not relatively rotate each other, can only synchronously rotate around planet axis 9, in order to the convenience illustrated, here these two planet sprockets are first set as the same size, use chain connection for transmission between main chain wheel 1 and primary planet sprocket wheel 4, this chain is called main chain 6 by the present invention, also uses chain connection for transmission between secondary sprocket wheel 2 and secondary planet sprocket 5, and this chain is called time chain 7 by the present invention.This just constitutes planetary gear derailleur of the present invention, be not difficult to find out from figure, it and traditional planetary transmission are similar, also three elements are had, i.e. main chain wheel 1, secondary sprocket wheel 2 and planet carrier 3, and the drive characteristic of these three elements is also almost identical, unlike the present invention, gear transmission is become sprocket driving, can difference to some extent with planetary transmission on rotation direction: when these three elements are all unfettered, planetary gear derailleur loses gearing completely; When two in these three elements are respectively as driving link and driven member, and when another element is fixed, then whole planetary gear derailleur is with certain velocity ratio transferring power; Between any two in these three elements can not relative movement time, then three elements in whole planetary gear derailleur all can not relative movement.Be equivalent to define direct high transmission and (but have individual special case here, namely when the velocity ratio between main chain wheel 1 and primary planet sprocket wheel 4 equals secondary velocity ratio between sprocket wheel 2 and secondary planet sprocket 5, although main chain wheel 1 can not relatively rotate with time sprocket wheel 2, planet carrier 3 can freely around central shaft system 8 rotation).
Fig. 2 is that planetary gear derailleur speed ratio of the present invention calculates auxiliary figure.
Because carry out except direct high transmission except the element of three in planetary gear derailleur is all fixed together, only have when in three elements any two respectively as driving link and driven member, and when another element is fixed, whole planetary gear derailleur is just with certain velocity ratio transferring power, as long as therefore one by one three elements are fixed, and the velocity ratio (gear ratio) obtained between other two elements, the present invention provides a kind of easy computational methods here: as Fig. 2-A, planet carrier 3 in figure is black thick solid lines, just in time overlap with the X-axis on coordinate, and central shaft system 8 is just in time in true origin, main chain wheel 1 there is 1 A also just in time drop in the X-axis on the initial point left side, in order to the aspect illustrated, the X-axis of secondary sprocket wheel 2 has drawn shade oblique line with lower part, so that observe, and set the number of teeth of main chain wheel 1 as m, the number of teeth of secondary sprocket wheel 2 is n, and m > n.When planet carrier 3 is fixed, when secondary sprocket wheel 2 is turned clockwise to 180 degree, then main chain wheel 1 just clockwise direction follow time sprocket wheel 2 to turn over an angle be θ, namely become as shown in fig. 2-b, obvious θ=n/m180 degree, the corner ratio in proper order between sprocket wheel 2 and main chain wheel 1 be 180/ θ=m/n, this is when planet carrier is fixed, rotating ratio between secondary sprocket wheel 2 and main chain wheel 1, and sense of rotation is identical.A point on main chain wheel 1 in Fig. 2-B leaves X-axis, if but whole for Fig. 2-B figure (except coordinate axes) is turned over an angle θ counterclockwise around true origin, then A point is still got back in original X-axis, and this is as shown in Fig. 2-C.Fig. 2-C can regard planet carrier 3 when main chain wheel 1 is fixed completely as and turn over θ degree counterclockwise, now secondary sprocket wheel 2 has turned over 180-θ degree clockwise, because the transmission direction between this sprocket wheel 2 with planet carrier 3 is contrary, its corner is than being (180-θ)/θ=(m-n)/n, this is the secondary rotating ratio between sprocket wheel 2 and planet carrier 3 when main chain wheel 1 is fixed, and direction of rotation; Again whole for Fig. 2-B figure (except coordinate axes) is turned over 180 degree counterclockwise around true origin, position when then original Fig. 2-A got back to by secondary sprocket wheel 2, be equivalent to be fixed, as depicted in fig. 2-d, now planet carrier 3 has turned over 180 degree counterclockwise, and main chain wheel 1 has also turned over 180-θ degree counterclockwise, the corner therefore between main chain wheel 1 and planet carrier 3 has been equidirectional rotation than being (180-θ)/180=(m-n)/m.
It should be noted that: the primary planet sprocket wheel that specifies in Fig. 24 is onesize with time planet sprocket 5, and main chain wheel 1 is in different size with time sprocket wheel 2, this is not only to allow computational process simplify, and in fact also represents a general design philosophy.Once discuss with regard to the size cases of each sprocket wheel in planetary gear derailleur of the present invention below: one, when primary planet sprocket wheel 4 is equal with time planet sprocket 5, and when making main chain wheel 1 and time sprocket wheel 2 also equal, so whole planetary gear derailleur becomes one and only has planet carrier 3 freely to rotate, and main chain wheel 1 and time sprocket wheel 2 cannot devices (being equivalent to the situation during m=n in previous calculations formula) in relative rotation, situation when this and the velocity ratio between the main chain wheel 1 said above and primary planet sprocket wheel 4 equal the velocity ratio time between sprocket wheel 2 and secondary planet sprocket 5 is the same, this is a special case, it is a special nature of the present invention.Two, when primary planet sprocket wheel 4 is equally large with time planet sprocket 5, and main chain wheel 1 is when being less than time sprocket wheel 2, situation when this situation and main chain wheel 1 are greater than time sprocket wheel 2 is the same, because the present invention to sprocket wheel titled with " master " or " secondary ", effect is difference two sprocket wheels, pure is because of the needs illustrated for it, therefore no matter be that main chain wheel 1 is large, or time sprocket wheel 2 is large, as long as simply large that is seen as main chain wheel 1: three, when main chain wheel 1, secondary sprocket wheel 2, primary planet sprocket wheel 4 and time these four sprocket wheels of planet sprocket 5 all different large time, as shown in Figure 3, this situation also can illustrate in fact very simply, the way that we can adopt sprocket wheel to replace completely, make it to become primary planet sprocket wheel 4 equal with time planet sprocket 5 time situation.Suppose that the velocity ratio between main chain wheel 1 and primary planet sprocket wheel 4 is a, as long as so we first find a sprocket wheel onesize with time planet sprocket 5 to replace original primary planet sprocket wheel 4, an energy is looked for form with the primary planet sprocket wheel 4 newly replaced the sprocket wheel that velocity ratio is a again, replace original main chain wheel 1, so just, the velocity ratio obtained between a main chain wheel 1 and primary planet sprocket wheel 4 is a, and the planetary gear derailleur that primary planet sprocket wheel 4 is equal with time planet sprocket 5, this be replaced with sprocket wheel before that planetary gear derailleur be equal to completely.Primary planet sprocket wheel 4 why is set equally large with time planet sprocket 5, namely this reason in Fig. 2.
Fig. 4 is sprocket wheel and gear planetary gear derailleur schematic diagram used in combination, this be equivalent to sprocket driving part replace gear transmission in planetary transmission, and the planetary gear derailleur of the gear obtained and sprocket wheel mixed drive, the present invention is called gear type planetary gear derailleur.Main chain wheel 1 in figure replace by master gear 10, primary planet sprocket wheel 4 replace by main planetary gear 11, obviously this also can implement the present invention completely.Because gear transmission is just in time contrary with the sense of rotation of original sprocket driving, therefore, this gear type planetary gear derailleur is closest to original planetary transmission, master gear 1 on it is equivalent to sun gear, secondary chain 7 is then equivalent to a soft ring gear be arranged on time sprocket wheel 2, but ring gear cannot do equally large (existing differential mechanism can be described as with sun gear by planetary transmission, but structure differs greatly), but the size of secondary sprocket wheel 2 in the present invention is by the restriction of master gear 10, can waits large completely and become differential mechanism.Also when the velocity ratio namely between master gear 10 and main planetary gear 11 is numerically equal to the velocity ratio of time sprocket wheel 2 and time planet sprocket 5, gear type planetary gear derailleur of the present invention just becomes a differential mechanism, the input end of this differential mechanism is that planet carrier 3 (can be made a sprocket wheel by planet carrier 3 simply, direct chain carries out transmission), two output terminals are master gear 10 and time sprocket wheel 2 respectively.As can be seen here, for the present invention, differential mechanism also belongs to speed changer, is the speed changer under certain specific velocity ratio, once velocity ratio changes, this differential mechanism also just becomes speed changer.
Fig. 5 is two differential mechanism schematic diagram of the present invention.In right Fig. 5-A, the left side is master gear 10 and two main planetary gears 11, and centre is planet carrier 3, has made a larger sprocket wheel here, can use chain-driving simply, can certainly make umbrella gear transmission shaft driven, but cost be higher; The right is two Chain conveyer pairs that two sprocket wheels 2 and two secondary planet sprockets 5 form, here chain is represented by dashed line, whole differential mechanism can have a shell, as shown in the dot and dash line in figure, but can there is no shell yet, allow outside these gears and sprocket wheel be directly exposed to because the installation shaft of the master gear 10 in Fig. 5-A is nested together with the installation shaft of time sprocket wheel 2, can be formed completely one firmly overall.Fig. 5-B is also a differential mechanism, its structure is slightly different, the internal works of whole differential mechanism has been wrapped up by planet carrier 3, and in outside, sprocket has been installed, although this structure complexity a bit, but effect is (if necessary, also the installation shaft of master gear 10 and the installation shaft of time sprocket wheel 2 can be resembled to overlap Fig. 5-A and load, then structure can be more firm) better.
The planet carrier 3 of two differential mechanisms is in Figure 5 installed all symmetrically two planet axis 9, two main planetary gears 11 and two planet sprockets 5, the spin balancing (dynamic balancing) of differential mechanism is mainly tried to achieve in its effect, next improves driving torque, obviously, all embodiments of the invention above, in order to the balance rotated, all can adopt the method.
This differential mechanism of the present invention, because the active force between each transmission is radially direct, produces without axial force, therefore structure is very simple, for the differential mechanism that common compact running mechanism uses, its thickness only has several centimetres, and therefore this differential mechanism is very cheap practical.
Fig. 6 is two and carries out anti-chaindriven sprocket wheel layout schematic diagram.This planetary gear derailleur with anti-chain drive mechanism is called anti-chain formula planetary gear derailleur by the present invention.Intermediate chain wheel in Fig. 6-A is contrary with the sense of rotation of upper and lower two sprocket wheels, clearly, adopt this anti-chain transmission, one is all carried out transmission differential mechanism by sprocket wheel can be made, middle sprocket wheel is just in time arranged on an output shaft on differential mechanism, and upper and lower two sprocket wheels are just in time arranged in two planet axis 9 (as the planet axis of two in Fig. 5) on planet carrier 3.Sprocket wheel in the middle of Fig. 6-A does less, mainly in order to not make chain and its generation friction on right side.As the sprocket wheel system of centre is large, then guide plate can be adopted to be separated by chain.Intermediate chain wheel and right side chain are carried out with a sprocket wheel on the right the anti-chain transmission schematic diagram that separates by Fig. 6-B, and the intermediate chain wheel in figure is contrary with the sense of rotation of the sprocket wheel of three on its periphery, and this is also anti-chaindriven a kind of method for arranging.Obviously, adopt this anti-chain transmission, not only can make differential mechanism, and the transmission can replaced completely in various embodiments of the present invention above and implement the present invention.
Although the rotating speed of traveller is not generally very high, we still will strive making the dynamic balancing of whole differential mechanism reach best, the more difficult adjustment of obvious anti-chaindriven dynamic balancing, effect is good unlike the differential mechanism in Fig. 5, as long as but careful counterweight, meticulously adjust, its effect also can be very desirable.
In sum, planetary gear derailleur of the present invention, not only there is the shifting characteristics the same with planetary transmission, simultaneously because the sense of rotation of sprocket driving can be contrary with gear transmission, therefore the present invention also can make up the deficiency of planetary transmission in some transmission direction: during as fixed by planet carrier 3, according to the drive characteristic of planetary transmission, peripheral ring gear is contrary with the sense of rotation of sun gear, but utilization the present invention not only completely can when planet carrier 3 be fixed, main chain wheel 1 is made to carry out equidirectional rotation (as shown in Figure 1) with time sprocket wheel 2, and can reciprocally rotate (as Fig. 4, shown in Fig. 6), in fact, light relies on this point, planetary gear derailleur of the present invention, just its existent value is provided with, this is gathering in the crops greatly of pursuing beyond low cost manufacture in the present invention.In addition use anti-chain formula of the present invention and gear type planetary gear derailleur and the differential mechanism made, have structure simple, the plurality of advantages such as easy to manufacture, volume is little, and cost is low are products having market potential.
Planetary gear derailleur of the present invention; multiple structural type (as mixed etc. in undertaken by ring gear and sprocket driving) can be had; here illustrate no longer one by one; for the person of being familiar with of all speed changers; after having read the present invention; naturally also can make more multiple structural change, everything all should belong to protection scope of the present invention.
