Изобретение относитс  к приборостроению .The invention relates to instrumentation.

Известен магнитный подвес на посто нных магнитах, содержащий вал, смонтированный в корпусе посредством радиальных магнитных подшипников и осевых механических упоров, и неподвижно установленное на валу подвижA known magnetic suspension with permanent magnets, comprising a shaft mounted in the housing by means of radial magnetic bearings and axial mechanical stops, and a fixed motion mounted on the shaft

ное звено {1}.link {1}.

Недостатком известного магнитного подвеса  вл етс  то, что в нем имеютс  потери на трение в механических упорах и быстрый их износ от воздействи  осевых сил, создаваемых подвижным звеном. Это гравитационные .или инерциапьные силы, действучадие при ускорени х, что снижает надежность и долговечность. The disadvantage of the known magnetic suspension is that there are friction losses in the mechanical stops and their rapid wear due to the axial forces generated by the moving link. These are gravitational or inertial forces acting on accelerations, which reduces reliability and durability.

Цель изобретени  - гоэвымение надежности и долговечности путем защиты осевых механических упоров магнитного подвеса от воздействи  осевых сил.The purpose of the invention is to demonstrate reliability and durability by protecting the axial mechanical stops of the magnetic suspension from the effects of axial forces.

Указанна  цель достигаетс  тем, что магнитный подвес, содержавши вал, смонтированный в корпусе посредством радиальных магнитных подшипников и осевых механических упоров , и установленное на валу подвижное звено, снабжен упорным магнитным подшипником дл  осевой стабилизации ПОДВИЖНОГО звена, при этом подвижное звено установлено на валу с возможностью осевого перемещени .This goal is achieved by the fact that the magnetic suspension, containing the shaft mounted in the housing by means of radial magnetic bearings and axial mechanical stops, and the movable link mounted on the shaft, is equipped with an axial magnetic bearing for axial stabilization of the MOBILE link, while the movable link is mounted on the shaft axial movement.

5 На чертеже изображен предлагаекый магнитный подвес.5 The drawing shows the proposed magnetic suspension.

Магнитный подвес содержит вал 1, смонтированный в корпусе 2 на радиальных магнитных подшипниках 3Magnetic suspension contains shaft 1 mounted in housing 2 on radial magnetic bearings 3

и осевых механических упорах 4. and axial mechanical stops 4.

На валу I установлено с возможностью осевого перемещени  подвижное звено 5. Дл  стабилизации подвижного звена 5 в оСевом направлении относи15 тельнр корпуса 2 подвес имеет упорный магнитный подшипник, состо щий из цилиндрического магнита 6, установленного на подвижном звене 5, и двух фиксированных в корпусе 2 магнитовThe movable link 5 is mounted on the shaft I for axial movement. To stabilize the movable link 5 in the axial direction relative to the housing 2, the suspension has a thrust magnetic bearing consisting of a cylindrical magnet 6 mounted on the moving link 5 and two magnets fixed in the housing 2

20 If соосных цилиндрическому магниту 6.20 If coaxially cylindrical magnet 6.

В случае приложени  к подвижному звену внешних осевых сил, последние будут смещать его (в пределах рабочего зазора) до наступлени  равНо25 веси  сил внешних и магнитных. При этом подвижное звено будет скользить по поверхности валов 1,не нагружа  упоры 4. Таким образом, упоры защищены от осевых сил, приложенныхIf an external axial force is applied to the moving link, the latter will displace it (within the working gap) until the onset of equal to 25 weight of external and magnetic forces. In this case, the movable link will slide along the surface of the shafts 1, without loading the stops 4. Thus, the stops are protected from axial forces applied

дл  удержани  подвижных магнитов радиальных магнитных подшипников 3 в среднем положении и при этом практически не нагру жены магнитными силёкм этих подшипников, следовательно, могут работать сравнительно долго. Внешние силы любого направлени  (как осевые, так и радиальные) в предлагаемом подвесе компенсируютс  магНИТНЫЛВ1 силами пар взаимодействуюших ПОСТОЯннЕлх магнитов, т.е. получен практически почти полный (трехосный) магнитный подвес на посто нный магнитах , В предлагаемом магнитном подвесе предпочтительно использовать посто нные магниты в силу их неограниченной долговечности, простоты и надежности.to keep the moving magnets of the radial magnetic bearings 3 in the middle position and at the same time practically not loaded with the magnetic forces of these bearings, therefore, they can work for a relatively long time. The external forces of any direction (both axial and radial) in the proposed suspension are compensated for by magnetism by the forces of pairs of interacting permanent magnets, i.e. An almost complete (three-axis) magnetic suspension with permanent magnets is obtained. In the proposed magnetic suspension, it is preferable to use permanent magnets due to their unlimited durability, simplicity and reliability.
