Изобретение относитс к волновым механическим перепа ем и может быть использовано в механических трансмиссн х .This invention relates to wave mechanical nib and can be used in mechanical transmissions.

Известна волнста передача, содержаща гибкое и жесткое колеса и малоинерционный кулаГчковый генератор волн. Между гибким колесом и кулачком генератора установлен гибкий подщипник 1.The wave transmission is well-known; it contains flexible and rigid wheels and a low-inertia kulaguch generator of waves. Between the flexible wheel and the generator cam, a flexible support plate 1 is installed.

Недостатком передачи вл ютс знач№ 1о тельные потери на трение в гибком подшипнике кулачковпч) генератора, определ ющие КПД всей передачи.The disadvantage of transmission is the significant friction losses in a flexible camshaft bearing of the generator, which determine the efficiency of the entire transmission.

Наиболее близкой к изобретению вл етс волнова передача, содержаща гиб- is кое и жесткое колеса и магнитный генератор волн, включающий кулачок и посто нный кольцевой магннт. Посто5шный кольцевой мапшт выполнен жестким и непоовижным , а кулачок представл ет со- 20 бой сплощной овухверишнный овал f 2.Closest to the invention is a wave transmission comprising a flexible and rigid wheels and a magnetic wave generator including a cam and a constant ring magnet. The posterior ring map is rigid and non-editable, and the cam is a solid oval f 2 oval.

Недостатком известной передачи &л етс мала нагрузочна способность.A disadvantage of the known transfer ability is small load capacity.

обусловленна наличием нескольких воздуишых зазоров, создающих значительное сопротивление магнитному потоку.due to the presence of several air gaps, creating significant resistance to magnetic flux.

Це.11Ь изобретени - увеличение нагрузочной способности передачи.The purpose of the invention is to increase the load capacity of the transmission.

Поставленна цель достигаетс тем, I что в волновой передаче, содержащей гибкое и жесткое колеса и магнитный генератор волн, включающий кулачок и посто нный кольцевой магнит, этот магнит вытголнен гибким и установлен между гибким колесом и кулачком, последний выполнен в виде двух посто нных стержневых магнитов, обращенных одноименными полюсами к одноименному полюсу ко/шцевого магнита и установленных с возможностью радиальных перемещений.The goal is achieved by the fact that in a wave transmission containing a flexible and rigid wheels and a magnetic wave generator, including a cam and a permanent ring magnet, this magnet is made flexible and is installed between the flexible wheel and cam, the latter is made in the form of two permanent rod magnets , turned by poles of the same name to the same pole of the co / slotted magnet and installed with the possibility of radial displacements.

Claims

Wave transmission with magnetic wave generator contains flexible wheel I, hard wheel 2, shaft 3 of the wave generator, permanent rod magnets 4 with common heads, spring 5, pins 6 and a flexible ring shaped post-shaped split magnet. The flexible ring & second permanent magnet 7 is fastened securely to the inner nf surface of the flexible wheel 1 in the area of the ring gear, for example, by glueing, the permanent magnets 4 are mounted inside the radial pilinthric direction of the shaft 3 of the wave generator with the possibility of movements along their axes under the action of the spring 5, and from rotation around their axes they are prevented from being directed towards the dimi pins 6 entering & the corresponding grooves of the magnets 4. Transmission works in a punt-like manner. Under the action of the spring 5, as well as the centrifugal forces of the inertia, when the shaft 3 of the wave generator rotates, the permanent magnets 4 move apart and form through the intermediate backing ring, which is the magnet 7, the flexible wheel I ensures that the sponge crowns of the flexible I and hard 2 wave transfer wheels. The flexible ring permanent magnet 7 and the permanent rod magnets 4 are magnetized and assembled in the design of the mechanism, so that they are directed towards each other by poles of the same name. In this case, mutual repulsive forces arise between them, which exclude their mechanical contact and ensure the preservation of a certain radial gap a. The magnitude of the required radial force P for deforming | a flexible wheel with a porous ring, taking into account the magnitude of the transmitted steep torque on the driven link and the magnitude of the radial gap a 14 between, the inner surface of the ring magnet 7 and the outer surface force of the profile heads of bar magnets 4 It is provided by an appropriate calculation of the magnitudes of the force of the spring 5 and the magnetic force field in the gap a with the close interaction of the magnets 4 and 7 of the same poles. By making the permanent ring magnet flexible and placing it between the flexible wheel and the cam, which is made in the form of two permanent rods; of magnets, the amount of air gaps in the path of magnetic fluxes is reduced to one, which reduces the magnetic flux resistance and increases the load capacity of the transmission. An invention of a wave transmission comprising a flexible and rigid wheels and a magnetic wave generator, including a cam and a permanent ring magnet, which is designed to increase the load. The constant constant magnet is flexible and is installed between the flexible wheel and cam, the latter is made in the form of two permanent rod magnets turned by the same poles to the same pole of the ring magnet and installed with the possibility of radial displacements.
