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, and four high-frequency impulse field coils divide two groups, and are symmetrical arranged, and are constituted 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 gaps 0.005mm 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 when use.The utility model can make bearing work under no state of wear, to improve the operating accuracy and stationarity of servo motor, and improve the service life of servo motor rotor.
Description
Technical field
The utility model is related to a kind of magnetic suspension swivel bearings, belong to technical field of bearings.Using magnetic suspension swivel bearing
Main shaft can be made to work 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.To be proposed more to bearing
High requirement.
Utility model content
The purpose of this utility model is to provide a kind of magnetic suspension swivel bearing, using thrust electromagnetic field main shaft to suspend
Mode is fixed on central axis, enables the floated rotary motion of main shaft.To make main shaft inorganic base wear, high machinery essence is kept
Degree.
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, it is described
Coil windings include 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 arranged, and is constituted rotating around being located on four stems of circuital magnetization body.The magnetic made of nano-high molecule magnetic material
Ring is arranged in coil group, and concentric laying.0.001--- is formed between four high-frequency impulse field coils and magnet ring
The gap of 0.005mm.
Operation principle
Magnet ring is installed on main shaft made of nano-high molecule magnetic material.When high-frequency electrical pulses field coil is powered,
Four high-frequency electrical pulses field coils on magnetizer, with the toroidal magnetic field of intensity same polarity, form circumference with generation on magnet ring
Interior thrust electromagnetic field is in a floating manner fixed on armature spindle on central axis, makes rotor suspension formula rotary motion, to
Any mechanical wear is not generated, can keep permanent mechanical precision in this way.
The utility model can make bearing work under no state of wear, to improve the operating accuracy peace of servo motor
Stability, and improve the service life of servo motor rotor.
Description of the drawings
Fig. 1 is a kind of example structure schematic diagram of utility model.
Specific implementation mode
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 impulses
Field coil 1, four high-frequency impulse field coils 1 divide two groups, and are symmetrical arranged, and rotating around being located at the four of circuital magnetization body 4
It is constituted on a stem 5.The magnet ring made of nano-high molecule magnetic material is arranged in coil group, and concentric laying.Four
The gaps 0.001---0.005mm are formed between high-frequency impulse field coil 1 and magnet ring 3, are suspended and are rotated, without mechanical wear.
Magnet ring made of nano-high molecule magnetic material is installed on main shaft 2 when use.
