Description

A kind of magnetic bearing magnet
Technical field
The utility model is related to a kind of magnetic bearing magnet.
Background technology
In the prior art, magnetic bearing is a kind of supporting form by magnetic field force bearing load or suspension rotor.In recent years, This bearing have developed rapidly, especially in high speed, low frictional resistance, height(It is low)It is widely used under temperature and vacuum environment.Magnet It is generally block and be provided with multiple as the main element of magnetic bearing, then uniformly it is arranged on bearing inner race or bearing On outer ring, not only installation difficulty is big, and cost of manufacture is high, and magnetic field intensity is smaller, less stable.
The content of the invention
In order to overcome the shortcomings of there is a kind of above-mentioned, simple and compact for structure, installation of the utility model offer in the prior art Convenient, the magnetic bearing magnet of stable performance.
The technical scheme in the invention for solving the technical problem is:A kind of magnetic bearing magnet, including in cylinder Magnet body, the center of the magnet body is through there is axis hole, and it is logical that the periphery of the magnet body is evenly equipped with least 3 positioning Hole, the axis of the positioning through hole is parallel with the axis of the axis hole.
Further, the number of the positioning through hole is 6.
Further, the magnet body is made up of sintered neodymium iron boron material.
Further, the axial two ends end face of the magnet body is coated with one layer of magnetic conduction film layer, the magnet body One layer is coated with the inwall of cylindrical side wall and the axis hole every magnetosphere, should be described every one layer of wearing layer is coated with outside magnetosphere One layer of zinc coat is coated with outside magnetic conduction film layer and wearing layer and on the inwall of the positioning through hole.
When in use, magnet body can independently turn into bearing inner race or bearing outer ring to the utility model, when magnet sheet When body is as bearing inner race, magnet body can be installed by shaft hole sleeve outside rotating shaft in the positioning through hole of magnet body Keeper, keeper is mutually fixed with rotating shaft again, so as to realize the installation of magnet body, when magnet body is used as bearing outer ring, Magnet body can install keeper, keeper by shaft hole sleeve outside bearing inner race in the positioning through hole of magnet body Mutually fixed with bearing block again, so as to realize the installation of magnet body, easy for installation, low manufacture cost.
The beneficial effects of the utility model are:1st, magnet body can independently turn into bearing inner race or bearing outer ring, no It is only simple and compact for structure, and magnetic field intensity is big, good stability.2nd, magnet body realize installing by axis hole and positioning through hole and Positioning, easy for installation, low manufacture cost.3rd, positioning through hole selects 6, not only magnetic force stabilization, and material-saving.4th, magnet sheet Body is made up of sintered neodymium iron boron material, is more than N48 in particular by performance and magnetic energy product adds HCJ sum to be more than 60 Sintered Nd-Fe-B magnetic material be made, possess high magnetic property, its maximum magnetic energy product exceeds ferrite more than 10 times, magnetic Stable performance, and machining property is good, consequently facilitating processing.5th, the setting of magnetic conduction film layer, magnetic conduction effect is good.6th, every magnetosphere Setting, prevent iron filings etc debris adsorb on the cylindrical wall and axis hole of magnet body so that influence magnet body turn It is dynamic.7th, the setting of wearing layer, can effectively prevent magnet body from being worn and torn because of rotation.8th, the setting of zinc coat, rotproofness is good, because In malaria, Several Thiourea Derivatives on Zinc Plate Surface can form one layer of very thin and compact oxide layer, and it is difficult to be dissolved in water, therefore to zinc coat Play a protective role, if after oxide layer generates insoluble zinc salt with other compositions in air, corrosion-resistant effect is more preferable, Magnet body to being made up of sintered neodymium iron boron material has protective effect.
Brief description of the drawings
Fig. 1 is stereogram of the present utility model.
Fig. 2 is sectional view of the present utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Reference picture 1, Fig. 2, a kind of magnetic bearing magnet, including in the magnet body 1 of cylinder, in the magnet body At the heart at least 3 positioning through hole 3, the axis of the positioning through hole 3 and institute are evenly equipped with through the periphery for having axis hole 2, the magnet body The axis for stating axis hole 2 is parallel, preferably, the number of the positioning through hole 3 is 6.
When in use, magnet body 1 can independently turn into bearing inner race or bearing outer ring to the utility model, when magnet sheet When body is as bearing inner race, magnet body 1 can be sleeved on outside rotating shaft by axis hole 2, installed in the positioning through hole 3 of magnet body Upper keeper, keeper is mutually fixed with rotating shaft again, so as to realize the installation of magnet body 1, when magnet body 1 is used as bearing outer ring When, magnet body can be sleeved on outside bearing inner race by axis hole 2, and keeper is installed in the positioning through hole 3 of magnet body, fixed Position part is mutually fixed with bearing block again, so as to realize the installation of magnet body 1, easy for installation, low manufacture cost.And magnet body 1 can independently turn into bearing inner race or bearing outer ring, be not only simple in structure compact, and magnetic field intensity is big, good stability.Positioning Through hole 3 selects 6, not only magnetic force stabilization, and material-saving.
The magnet body 1 is made up of sintered neodymium iron boron material, add more than N48 and magnetic energy product in particular by performance in Report sintered Nd-Fe-B magnetic material of the coercivity sum more than 60 to be made, possess high magnetic property, its maximum magnetic energy product exceeds More than 10 times of ferrite, magnetic property stabilization, and also machining property is good, consequently facilitating processing.
The axial two ends end face of the magnet body 1 is coated with one layer of magnetic conduction film layer 4, the cylindrical side of the magnet body One layer is coated with the inwall of wall and the axis hole 2 every magnetosphere 5, should be every being coated with one layer of wearing layer 6, the magnetic conduction outside magnetosphere One layer of zinc coat 7 is coated with outside film layer 4 and wearing layer 6 and on the inwall of the positioning through hole 3.The setting of magnetic conduction film layer 4, Magnetic conduction effect is good, every the setting of magnetosphere 5, prevents the debris of iron filings etc from adsorbing on the cylindrical wall and axis hole of magnet body, from And the rotation of magnet body is influenceed, the setting of wearing layer 6 can effectively prevent magnet body from being worn and torn because of rotation, and zinc coat 7 sets Put, rotproofness is good, because in malaria, Several Thiourea Derivatives on Zinc Plate Surface can form one layer of very thin and compact oxide layer, and it is difficult Water is dissolved in, therefore zinc coat is played a protective role, if after oxide layer generates insoluble zinc salt with other compositions in air, it is resistance to Corrosiveness is more preferable, and the magnet body to being made up of sintered neodymium iron boron material has protective effect.
