Abstract
The invention discloses a kind of wind-driven generator magnetic suspension bearing, formed including thrust disc from top to bottom, coiling keel and stator, several positioning holes are evenly distributed with the thrust disc, the coiling keel side sets fluted, the stator upper surface is provided with several spacing holes, and stator lower surface is provided with endless groove.The present invention separates stator and rotor using magnetic levitation technology, and so as to reduce startup fan and reduce friction, the bearing sends electromagnetic force and forces rotor suspension on stator after powered up.
Description
Technical field
The present invention relates to generator associated components field, more particularly to a kind of wind-driven generator magnetic suspension bearing.
Background technology
Wind-power electricity generation is that China substitutes one of traditional thermal power generation and hydroelectric important technology as clean energy resource.And
Our small-sized wind power generator is a kind of parallel net type solution provided for family or Small Groups, but in this total generating work(
The substantial amounts of kinetic energy of frictional dissipation of rate traditional bearing in below 10kw generator, make the electric energy delivery efficiency of actual converted low
Under.And kinetic energy must pull against bearing friction power so threshold wind velocity requirement is very harsh, mostly under traditional bearing
Area is without the wind field that can meet such condition for a long time.So designing this magnetic suspension bearing, make rotor suspension after powered up.To be rubbed sassafras
Power is reduced to ultimate attainment.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, present invention offer is a kind of easy to use, simple in construction
Wind-driven generator magnetic suspension bearing.
Technical scheme：To achieve the above object, the present invention provides a kind of wind-driven generator magnetic suspension bearing, including by upper
Thrust disc, coiling keel and stator under and are formed, and several positioning holes, the coiling dragon are evenly distributed with the thrust disc
The setting of bone side is fluted, and the stator upper surface is provided with several spacing holes, and stator lower surface is provided with endless groove.
Further, the quantity of the positioning hole is no less than six.
Further, the depth of the groove is 25-30mm, and the width of groove is 11-15mm.
Further, the quantity of the spacing hole is no less than eight.
Further, the depth of the endless groove is 22-28mm, and the width of endless groove is 32-38mm.
Further, the thickness of the thrust disc is 15-18mm.
Further, the thickness of the coiling keel is 20-25mm.
Further, the thickness of the stator is 40-45mm.
Further, the thrust disc and stator are that pure iron material is made.
Further, the coiling keel are made up of polytetrafluoroethylmaterial material.
Beneficial effect：The present invention has advantages below compared with prior art：Bearing is divided into three-decker, is thrust respectively
Disk, bobbin and stator；Wherein thrust disc and stator is processed using electrical pure iron, can reach magnetic force maximum using the material
Change.Coiling keel use nonconducting polytetrafluoroethylmaterial material.

Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
A kind of wind-driven generator magnetic suspension bearing, including thrust disc, coiling keel and stator composition from top to bottom, institute
State and several positioning holes are evenly distributed with thrust disc, the coiling keel side setting is fluted, and the stator upper surface is set
Several spacing holes are equipped with, stator lower surface is provided with endless groove.Thrust disc is used for connecting blade-section.After powered up can be with determining
Son separation.Needed in coiling keel after being calculated by design requirement around entering copper cash.Stator clock is put into after the completion of coiling keel coiling simultaneously
Fix, wire picks out from joint location, then the upper master section of stator connection.Magnetic suspension bearing produces magnetic force after being powered and pushed away
Power disk is separated with stator.
The quantity of positioning hole is no less than six.The depth of groove is 25-30mm, and the width of groove is 11-15mm.Spacing hole
Quantity be no less than eight.The depth of endless groove is 22-28mm, and the width of endless groove is 32-38mm.The thickness of thrust disc is
15-18mm.The thickness of coiling keel is 20-25mm.The thickness of stator is 40-45mm.Thrust disc and stator are pure iron material
It is made.Coiling keel are made up of polytetrafluoroethylmaterial material.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
