Abstract
The invention discloses an axial magnetic suspension bearing of two magnetic rings with opposite poles. The axial magnetic suspension bearing comprises an axial magnetizing big magnetic ring (1), an axial magnetizing small magnetic ring (2), a main shaft (3) and the like; the axial magnetizing big magnetic ring (1) and the axial magnetizing small magnetic ring (2) are concentric, the polarities of the opposite end faces are opposite, and the axes of the end faces are not parallel; and the axial magnetizing small magnetic ring (2) is fixed with the main shaft (3) together.
Description
Affiliated technical field
The present invention relates to a kind of two axial magnetic suspension bearings that the magnet ring antipole is relative.Permanent magnet is a homopolar-repulsion, and antipole is inhaled mutually, if two magnet ring antipoles are installed can be drawn onto together.But the magnet ring of different-diameter as long as make the magnetic pole end face not directly not relatively, all can produce axial repulsion.Relative the magnet ring antipole of two different-diameters, and keep end face to be in axial not parallel position, just can realize the axial suspension of two magnet rings.Belong to the magnetic levitation technology field.
Background technique
In our general knowledge, the end face of permanent magnet is that the same sex is repelled each other, and there is a natural attraction between the sexes.Naturally, the peripheral region of permanent magnet end face also can keep identical polarity with the permanent magnet end face.
But actual conditions are just in time opposite, and when the permanent magnet end face presented the N utmost point, permanent magnet end face peripheral region can present the S utmost point.The S utmost point that this measurement obtains is not an illusion, is to produce repulsion magnetic field to the extreme face of other magnetic patch S.Antipole magnetic field, this end face outside is not on the books in any textbook, and one that writes the German is cried also not record in " magnetic suspension bearing " book, and this this book is considered as treasured book by the professor of the many universities of China, is praised highly, and strictly observes.If there is not this discovery, German viewpoint also is installed does, encircle the built-in type axial magnetic suspension bearing more and just can not realize.The efficient of axial magnetic suspension bearing just can not improve, and can not accomplish to eliminate radial frictional force when realizing axial magnetic suspension.
Summary of the invention
Principle of the present invention is with two magnet rings that diameter is different, makes it under the concentric state of maintenance, and end face can not be parallel relative; Make two magnet rings be in the antipole relative status simultaneously, such two magnet rings just can be realized mutual axial suspension.
When big magnet ring and bead do not have overlapping mutual cover, there is bigger suction between two magnet ring end faces, just there is bigger radially power partially; After bead entered big magnet ring inboard, its axial suspension power can change, and had a maximum value; But radially suction can reduce gradually, until complete obiteration.So just can accomplish when realizing axial magnetic suspension, eliminate radially power partially.
Only occur in addition after this phenomenon, we just might realize the axial magnetic suspension of cover mutually of many rings.
Under the constant situation of arranging structure, when the mechanical structure of magnet ring self changes, can not influence the generation of above-mentioned axial suspension.
Description of drawings
Fig. 1 is the radial section tectonic maps of the relative axial magnetic suspension bearing of two magnet ring antipoles of the present invention.
The present invention will be further described below in conjunction with accompanying drawing.
Among Fig. 1, the big magnet ring of axial charging (1), axial charging bead (2) and main shaft (3) etc.; The big magnet ring of axial charging (1) is in concentric with axial charging bead (2), and opposing end surface polarity is opposite; End face axial is not parallel; Axial charging bead (2) is installed together with main shaft (3).
The big magnet ring of axial charging this moment (1) will be in mutual axial suspension state with axial charging bead (2).
Claims (1)
1. two axial magnetic suspension bearings that the magnet ring antipole is relative is characterized in that: the big magnet ring of axial charging (1), axial charging bead (2) and main shaft (3) etc.; The big magnet ring of axial charging (1) is in concentric with axial charging bead (2), and opposing end surface polarity is opposite; End face axial is not parallel; Axial charging bead (2) is fixed together with main shaft (3).
