Abstract
A kind of magnetic suspension swivel bearing, is mainly made of magnet ring and coil windings, and the magnet ring is magnet ring made of nano-high molecule magnetic material；The coil windings include four high-frequency impulse field coils, four two groups of high-frequency impulse field coils point, and are symmetrical arranged, and are formed rotating around being located on four stems of circuital magnetization body.The magnet ring made of nano-high molecule magnetic material is arranged in coil group, and concentric laying.0.001 0.005mm gaps are formed between four high-frequency impulse field coils and magnet ring.Magnet ring made of nano-high molecule magnetic material is installed on main shaft during use.The present invention can make bearing work under no state of wear, so as to improve the operating accuracy of servomotor and stationarity, and improve the service life of servo motor rotor.
Description
Technical field
The present invention relates to a kind of magnetic suspension swivel bearings, belong to technical field of bearings.It can be made using magnetic suspension swivel bearing
Main shaft works under without mechanical state of wear.
Background technology
The indispensable mechanical part of bearing mechanical technical field is installed in the both ends of main shaft, and main shaft rotating friction force is small,
The mechanical wear of main shaft can be greatly reduced, reduce energy consumption.Therefore it is widely used in the support member of bearing.But certainly
Dynamicization technical field, mechanical rotation movement have higher precision, stationarity, smaller mechanical wear.So as to be proposed more to bearing
High requirement.
The content of the invention
It is an object of the present invention to provide a kind of magnetic suspension swivel bearing, using thrust electromagnetic field main shaft in a floating manner
It is fixed on central axis, enables the floated rotary motion of main shaft.So that main shaft inorganic base is worn, high mechanical precision is kept.
The technical solution adopted is that：
A kind of magnetic suspension swivel bearing, mainly by magnet ring（Moving-coil）It is formed with coil windings, it is characterised in that：
The magnet ring is nano-high molecule magnetic material（The rare earth permanent magnets mixing material such as neodymium iron boron）Manufactured magnet ring, the coil
Winding includes four high-frequency impulse field coils（Coil group is fixed circle）, four two groups of high-frequency impulse field coils point, and it is symmetrical
It sets, and is formed rotating around being located on four stems of circuital magnetization body.Magnet ring is set made of nano-high molecule magnetic material
It puts in coil group, and concentric laying.Form 0.001---0.005mm's between four high-frequency impulse field coils and magnet ring
Gap.
Operation principle
Magnet ring made of nano-high molecule magnetic material is installed on main shaft.When high-frequency electrical pulses field coil is powered, in magnetic
Change four high-frequency electrical pulses field coils on body with generating the toroidal magnetic field with intensity same polarity on magnet ring, formed in circumference
Thrust electromagnetic field is in a floating manner fixed on armature spindle on central axis, makes rotor suspension formula rotary motion, so as to not produce
Raw any mechanical wear, can so keep permanent mechanical precision.
The present invention can make bearing work under no state of wear, so as to improve the operating accuracy of servomotor and steady
Property, and improve the service life of servo motor rotor.
Description of the drawings
Fig. 1 is a kind of example structure schematic diagram of invention.
Specific embodiment
A kind of magnetic suspension swivel bearing, is mainly made of magnet ring 3 and coil windings, it is characterised in that：
The magnet ring 3 is magnet ring made of nano-high molecule magnetic material；The coil windings include four high-frequency impulse magnetic fields
Coil 1, four high-frequency impulse field coils 1 divide two groups, and are symmetrical arranged, and rotating around four cores for being located at circuital magnetization body 4
It is formed on column 5.The magnet ring made of nano-high molecule magnetic material is arranged in coil group, and concentric laying.Four high frequencies
0.001---0.005mm gaps are formed between pulsed magnetic field coil 1 and magnet ring 3, suspends and rotates, without mechanical wear.
Magnet ring made of nano-high molecule magnetic material is installed on main shaft 2 during use.
