Description
Technical field
The present invention relates to technical field of motors, especially a kind of rotor with novel magnetic source fixed structure.
Background technology
The rotor magnetic source system of prior art comprises: the rotor chip that the profile that the non-magnet material stainless sheet steel is made consists of for columniform fixed cover, the magnetic source that magnetic energy is provided, permeability magnetic material, the glue layer of bonding magnetic source and rotor chip.Magnetic source is pasted on the surface of rotor chip by glue, and the stainless steel fixed cover is socketed on the outer surface of magnetic source, and its effect is that magnetic source further is fixed on the rotor core surface.
The specification requirement of fixed cover is guaranteeing under the prerequisite that technique realizes, and is thin as far as possible, generally can only accomplish 0.3 millimeter: be effective air gap between the electric machine rotor because it takies, thus can not be too thick, in order to avoid affect motor performance.Magnetic source provides the part of motor rotation energy, is one of most important part of motor.The function of bonding glue is that magnetic source and rotor core are bonded together.Rotor core is the necessary element that consists of the motor magnetic circuit.
On technique, first stamping forming rotor core is cleaned up, apply glue at its outer surface and magnetic source inner surface, glue thickness is 0.2 millimeter, and be fixed on corresponding position, use corresponding drying equipment and means, make glue dries, put the fixed cover of being made by stainless sheet steel on the magnetic source surface, the parts technique of rotor is finished.
The advantage of prior art is simple in structure, is easy to realize; But significant shortcoming is arranged also: the non-magnetic stainless steel sleeve that stretch, Bao Yuehao is got in the principle requirement, but complicated on the technique, the thin and thick of bad assurance jacket wall is consistent; Because the fixed cover material is magnetic conduction not, therefore cause in the middle of the effective air gap of electric machine rotor, added the wall thickness of fixed cover, the air gap actual value is increased, affect the performance of motor; Such as: general stainless steel outer sleeve thickness is 0.3 millimeter, and bonding glue thickness is 0.2 millimeter, adds for 0.2 millimeter of the air gap of the smooth and easy rotation of process conditions, makes so the monolateral effective air gap between the electric machine rotor be at least 0.7 millimeter.So greatly increased the depletion of magnetic source in air gap transmits.Cause electric efficiency low, cost is high, and output torque is little.Because this fixed cover does not have adjusting function, therefore can not regulate the fastening force between magnetic source and the motor stator; Need extraordinary glue bonding magnetic source and rotor, need dry adhesive surface, two adhesive surfaces of cleaning, complex process, quality is unreliable.
Summary of the invention
In view of this, be necessary the problem mentioned for background technology, provide a kind of mounting process simple, fixing more reliable and can automatically regulate the adapter sleeve distortion that magnetic source produces because of temperature rise centrifugal force and the phenomenon that gets loose, make better novel rotor magnetic source technique for fixing of motor output performance.
The problem that exists in order to solve prior art, the technical solution used in the present invention is:
A kind of rotor with novel magnetic source fixed structure, it comprises by the stacking column rotor core that forms of multilayer magnetic conduction rotor lamination, be arranged at a plurality of magnetic sources of described rotor core outer surface, the corresponding a plurality of both sides that are arranged at described a plurality of magnetic source outer surfaces have the magnetic source fixed cover assembly of making every the permeability magnetic material in magnetic hole respectively; The even circumferential of described each rotor lamination is provided with a plurality of openings, each described opening extends and connects a draw-in groove greater than the size of this opening to center of circle direction, the both sides of the edge of described each magnetic source fixed cover assembly are provided with kink, the end of the two adjacent kinks of every adjacent two magnetic source fixed cover assemblies stretch in the same draw-in groove with described rotor core by the jump ring card and, thereby described a plurality of magnetic sources are fixedly clamped.
The end of the adjacent kink of every adjacent two magnetic source fixed cover assemblies be respectively equipped with opposite direction respectively towards the inferior kink of the both sides of the edge of described draw-in groove, described magnetic source fixed cover assembly and described rotor core by described kink and described draw-in groove by jump ring card and fixing, be provided with between this two kink that non-magnet material makes every magnetic stripe minimizing leakage field.
Described is strip every magnetic stripe, and it is doubling vertically, and two free margins are respectively to two lateral bucklings, with the adjacent secondary kink coupling of described adjacent two magnetic source fixed cover assemblies.
Be provided with one between each described kink and the described draw-in groove inside edge and regulate the tightening spring, this spring is strip, cross section is V-type, arch or U-shaped, the described kink of openend butt and/or the inferior kink of spring, the described draw-in groove of the top butt inside edge of spring.
Described number every the magnetic hole is a plurality of, and is evenly distributed along the length direction of described magnetic source fixed cover assembly.
With respect to prior art, advantage of the present invention comprises:
The present invention adopt can magnetic conduction fixed cover, because fixed cover has high permeability material to consist of, has opened every the magnetic hole to reduce leakage field on the fixed cover both sides, therefore, fixed cover does not have loss substantially to the conduction of magnetic energy, the back jump ring can guarantee that magnetic source connects closely in rotor, needn't the extremely low bonding mode of dependability.Therefore, can greatly reduce the air gap between the rotor, make the electric machine rotor air gap less than 0.2 millimeter, greatly improve the motor output performance, efficient, output torque, positioning accuracy etc.; Because the tightening regulating spring can be adjusted the fastening force of fixed cover and iron core magnetic source, so, can make magnetic source keep stable, and cancel bonding process, drying process, cleaning makes technique simple, reliable in quality.
