Description

The axial magnetic suspension rotary system

Affiliated technical field

The present invention relates to a kind of axial magnetic suspension rotary system, this system suspends the main shaft of vertical axis revolving equipment (for example blower) or axial tension rotating equipment (as the rotation propulsion system of propeller driven airplane) with magnetic suspension bearing, gravity or the load of main shaft and loaded article thereof are suspended with magnetic suspension bearing fully, keep main shaft and load on static and during rotation, be parallel to rotation axial load 100% and be in vacant state.Its suspending power comes from the opposite sex axial magnetic suspension bearing that repels each other.Belong to the magnetic levitation technology field.

Background technique

The rotary support of present various rotary systems is all to rely on conventional mechanical bearings, such as 02105914.4 and the blower such as 201020503605.X be all to adopt mechanical bearing as the rotary support structure, the rotating equipments such as other rotary system such as water turbine, pump, propeller driven airplane and washing machine, all to adopt as far as possible the horizontal axis form, support with mechanical bearing, yet the horizontal axis mechanical bearing can produce huge frictional heating phenomenon when High Rotation Speed, friction energy-dissipating is very large.A large amount of so valuable energy is all to have consumed in transmission process, is not actually used in our daily life.A large amount of energy consumption meetings causes the carbon emission amount to increase, and produces greenhouse gases, causes global warming.

Summary of the invention

Problem to be solved by this invention is that the gravity of the main shaft of rotary system and load thereof or reaction force are suspended fully, 100% when eliminating rotation gravity or the surface friction drag of reaction force, thoroughly eliminate the friction energy-dissipating of reaction force.

Principle of the present invention is that " axial magnetic suspension bearing with mutual cover of many rings of magnetic rock-steady structure " is arranged on the main shaft of rotary system, rotational structure (as blower wheel) is arranged on main shaft, makes main shaft be in complete state of suspension in the vertical-horizontal direction; Main shaft makes its central position that remains on whole bearing by mechanical device, can rotate simultaneously; Line shaft and suspension main shaft keep being rotationally connected, and perhaps power mainshaft and suspension main shaft are as a whole.

Rotational structure on main shaft can replace with the rotating equipments such as the blade of impeller, turbine impeller, washing machine drum, fan blade, wind stick, turbofan motor of blower wheel, pump and helicopter blade, also can support the container of large-scale mixing plant.The direction of its bearing capacity does not require definitely perpendicular to horizontal plane so long as be parallel to the direction of levitation axis and get final product.

The weight of the vertical major of rotary system and load rotational structure is just suspended fully like this, gravity friction during rotation is zero, the friction energy-dissipating of so main rotating part has not just had, the overall test result proves, blower through after the magnetic suspension repacking can obtain extraordinary energy-saving effect.The characteristics of gravity friction energy-dissipating are that weight is larger, and rotating speed is higher, and friction energy-dissipating is also larger, and the characteristics of vertical shaft maglev bearing are, no matter how weight and rotating speed increase, and friction energy-dissipating can not increase.Use magnetic suspension bearing more obvious at the energy-saving effect that large product is.
