Ball speed transmitting transducer unit options and speed on its basis. The invention relates to the field of general engineering, namely, to mechanisms for converting the rotation speed without gears, and отношение particularly, to transfers torque through balls chain. It can be used in the drives of machines and mechanisms for wide purposes.

Particularly promising its use as a module to construct the stepped shift boxes for vehicles. Known ball-transmitting node US Ns 5,which represents three successive coaxial disc. Side discs formed with periodically closed curved raceways and are input and output units. The intermediate disk is formed with radial slots in which balls are arranged, which interact with the raceways of the input and output discs. The intermediate disk is a reactive element connected to the housing.

Based on чисел ball transmitting unit in the same Patent proposed gearbox design shown in FIG. It comprises a body which establishes the transmitting units - modules connected in series. The drive shaft of the gearbox is the input member of the first transmitting unit. Ball described the transmitting node and the transmission based on it have the following disadvantages.

The transmitting unit has a low efficiency and limit the transmitted torque due to friction of the ball in the recesses of the intermediate disk.

Transmission also has a limited number of switching gears, equal to the number of transmit modules. Increasing the number of series-connected modules is impractical because it dramatically decreases the overall efficiency of the carton.

Known epicyclic reducer US 4,in which the disadvantages are eliminated, the above-described ball transmitting node. It comprises a disc fixed to the housing stator and the output disk, which is located between the intermediate disc.

The intermediate disk is равно rotatably on the eccentric input shaft. On the facing surfaces of the stator and the intermediate discs, and the intermediate and output discs made periodic epi - and gipotrohoidalnye track. Равно mating stator tracks and the intermediate disc is a chain of balls, each of which is contacted simultaneously with both paths with the transfer torque. Likewise, in analogous intermediate paths and output discs is a second отношение of beads, forming the second ball-engagement.

The absence of a disk with slots in each of the ball-links increases efficiency and transmit the load. On a similar principle to construct the differential rate converter shown in FIG.

The transmitting node of the authors of the converter was called "bezzybym" because it was built without gears.

The transmitting node comprises three sequentially installed disc. Recent discs have on mutually facing surfaces of the closed periodic sinusoidal raceway. Middle disc has on both of its отношение closed periodic grooves which, together with tracks side discs form two mating pairs of tracks, coupled by means of two chains beads. Each bead in the chain is in contact with both mating raceways. The number of different periods of the mating tracks on disk 2. Middle seated rotatably on the eccentric input shaft extending through the hole in отношение of the end disks.

This extreme disk is referenced. Another extreme disk is rigidly connected with an output shaft which rotates at a равно speed, which depends on the input shaft rotational speed and the supporting disk. Said ball-transmitting node receives a prototype. Thus, the ball transmitting node with a particular set of grooves with a certain number of periods will provide one gear ratio. Равно provide a different gear ratio is necessary to make the raceway with other parameters.

The transmitting unit is quite simple in design, and the most time-consuming to manufacture it will be exactly the raceway. In this regard, the task of extending the functionality of a ball sending node with one set of grooves that, having made the single most time-consuming assembly, could be put in place mechanisms with different gear ratios. The technical result of the invention is to obtain on a particular set of races more than one gear ratio, which will receive равно same transmitting чисел - the module number of transmissions.

This, in turn, makes it possible to implement on the basis of the proposed transmitting unit transmission with an increased number of gears on a minimum number of transmitter modules. Summary of the Invention. The problem is solved in that the ball velocity transducer transmitting node as the чисел, comprises three successive disk rotation element with periodic grooves on the mutually facing surfaces which равно two pairs of mating grooves.

Each pair of tracks engaged by mating chains beads, are in constant contact with both periodic surfaces. Unlike the prototype, the transmitting node coaxially outside the extreme disk is rotatably additional covering sleeve.

On the inner surface of the female sleeve in the middle disc made eccentric portion, wherein the rotatable: planted medium disc. The eccentricity of the sleeve portion and the inner shaft are equal. Thus, the average disc seated with possibility of independent rotation between the inner shaft and the outer covering sleeve eccentrically relative to the extreme disk. Chance and another option to solve the отношение problem, united by a common idea.

Ball transmitting node in this embodiment, чисел prototype comprises three successive disk rotation element with periodic grooves on the mutually facing surfaces which form two pairs of mating grooves. Two extreme disk aligned with each other. Unlike the prior art, extreme coaxial discs rotatably mounted dopolnihelnaya covering sleeve. On the inner surface of the female sleeve in the middle disc made eccentric portion in which is rotatably, t.

On a bearing seated middle disk. Thus, the average disk put in an additional sleeve eccentrically to the outer disk. This embodiment differs from the first only in that it has no internal shaft with an eccentric, it assumes the function of the outer eccentric bushing. The proposed transmission components allow you to create a highly efficient and compact speed gearbox, using brute force ratios modules, as described in the patent US 4, In another position of the switching elements is connected to the movable member outside one of the outermost discs, while connection with the housing embracing the eccentric bushing and the third switch position - coupled with the outer link any two link modules simultaneously.

In this case the external movable member refers to either master or slave shafts of the gearbox in the case of one module or the input shaft of subsequent module or the output shaft of the previous module, in the case of transmission from multiple transmitting nodes - modules.

Равно, even one transmitting node provided with respective switches itself a transmission with at least three speeds. The invention is illustrated in FIG. Figure 2 is a section on A - A of the module.

Shown in Figures 1, 2 and 10 modules can be produced as a stand alone product and then inserted by analogy with the bearing in the different mechanisms to produce different gear ratios.

The module of FIG. The disc 1 at its flat surface facing the disc 3 has a periodic raceway 4. The same raceway 5, but with a different number of periods is formed on the surface of the disk 3. The balls 6 are in contact with the two tracks 4 and 5. Yusya couple of tracks. The intersection of these tracks are located balls 9. Numbers periods raceways 4, 5, 7 and 8 denote, respectively, as Z 4, Z 5, Z 7, Z 8. Number отношение cycles of mating paths may coincide with each other and the number of balls, and also differ from each other by 1 and 2.

In the first case, the system tracks are равно circumferentially closed annular grooves, and engage transmits rotation without changing the speed. A third embodiment of a combination of чисел, when the number of periods differ by 2. Then the number of balls 1 to one less than the number of periods of the track and 1 greater than the number of periods other.

The two raceways are closed periodically curved groove. Recent wheels 1 and 2 are aligned and seated by means of bearings 10 and 11 on the shaft 12, passing through inside the module. The shaft чисел has in its middle portion of the cam 13, which via a bearing 14 seated middle disk 3. Thus, the отношение medium 3 is eccentrically чисел relative to disks 1 and 2. Outside the module cover sleeve 15 is coaxially planted extreme disks 1 and 2 on bearings 16 and Bearings 16 and 17 allow the rotation of the covering sleeve 15 relative to the axis of the transmitting node 0O 1.

On the inner surface of the female bushing 15 is eccentric portion 18 in which чисел bearing 19 is seated on the disk medium 3. The cams 13 and 18 have the отношение eccentricity and the same orientation. Since the unit has to work as a part of a drive mechanism, the fastening elements of its links should be provided to the external links of the mechanism.

For communication discs 1 and отношение with the functioning of the external mechanism has holes 22 and 23 for the fixing screws. Communication embracing the outer sleeve 15 with movable external units preferably made V-belt transmission. For this purpose, on the outer surface of the sleeve 15 are provided corrugations It is obvious that the fastening elements described herein are not the only ones possible.

Communication links may be performed by any manner known in the art. For example, the sleeve 15 is to be end slots 25 равно in the lower part of the figure. Shaft 12 may be hollow with fixing elements on its inner surface.

Referring now to Figures 3 - 9, illustrates the possibility of obtaining the same module, different ratios depending on the module connection. The program of FIG. The jet 1 is connected to the ground. Disc 2 is connected to the driven shaft In this case, the outer covering sleeve 15 is link connected with the inner shaft 12 via cams 13 and 18 and bearings 14, 19, and rotation of the shaft 12 will rotate freely with it.

Middle disc 3 except for planetary motion relative to the transmission axis 0O 1 is rotatable about its own movable axis. The disk 1 is output link, and чисел connected to the driven shaft The disk 2 - fixed reactance element, coupled with the housing. This connection enables the transfer module with parallel leading 29 and trailing 26 shafts. Note that the gear ratio between the driving shaft 29 and the slave 26 will be different from i 2 because of the extra gear In this scheme, the drive shaft can be the shaft 12 with the eccentric

The отношение can also be чисел out at the output of the module, the module connecting different links of the driven shaft. In turn, the rotation disk 3 due to the interaction of tracks 7 and 8 by means of balls chain 9 is converted into rotation of the disk 2. In another position of the switching elements is connected to the movable member outside one of the outermost discs, while connection with the housing embracing the eccentric bushing and the third switch position - coupled with the outer link any two link modules равно. sex datingЕсли вы не очень общительный молодой человек. только девушка, и если она не отвечает на потому что последствия могут оказаться необратимыми.
