Last century, the nineties was come, and along with the fast development of correlation techniques such as power electronic technology, microelectric technique, modern electrical machine control theory and new material and complete, rare earth was introduced into elevator traction machine manufacturing technology field.Permanent magnetic synchronous traction machine becomes to have become the mainstream model of novel step traction machine.After 2008, country is to the energy-conservation and increasing environmental protection dynamics, and permanent magnetic synchronous traction machine has obtained using more widely.
The permanent magnet fixed form of permanent magnet motor generally has two kinds in the market, and a kind of is with pressing plate and screw permanent magnet; Another kind is that rotor and permanent magnet are adopted that glue is bonding, fill up with the material of mud shape between permanent magnet and the permanent magnet and fix.The shortcoming of said method one is: screwed hole is processed on rotor, the technology more complicated; Screwed hole is on pressing plate, and pressing plate must adopt the material that is fit to tapping, and cost height, processing are greatly.Adopt method two, the China Patent No. of the applicant's invention: 200710071174.7, remain in certain shortcoming: circumference calibration technology is relatively more difficult between permanent magnet/magnet steel and the permanent magnet/magnet steel, though the mud shape that adopts has curing and fills up effect, but need do dynamic balancing, still simple inadequately desirable.
Chinese patent does not have to find the technology identical with the utility model by retrieval.
Summary of the invention
The purpose of this utility model provides a kind of magnet steel fixture, is useful in permanent magnet/magnet steel fixing of permanent magnet motor and every the used device of magnetic.Have a shortcoming for overcoming prior art, the magnet steel fixture that provides has every magnetic and fixed permanent magnet/magnet steel double action, and characteristics such as good stability simple in structure, that installation and processing convenient, magnet steel is fixing, has filled up the blank of prior art.
Content of the present utility model is described as follows in conjunction with the accompanying drawings:
The utility model provides a kind of magnet steel fixture, comprises the rotor 1 and the magnet steel 2 that is arranged in the rotor 1 of permanent magnet motor, it is characterized in that:
Described rivet connecting rod 3 calibration be arranged in rotor 1 inwall face mutually two magnet steel 2 between,
Described rivet connecting rod 3 is by plastic plate 5 and vertically be arranged on the plastic plate 5 and have at least two rivet 4 to constitute,
Be provided with the hole for rivet 4 riveted joint usefulness on the inwall of described rotor 1, the size in this hole and quantity and set rivet 4 match,
The hole of the riveted joint usefulness on the rivet 4 on the described rivet connecting rod 3 and rotor 1 inwall connects 2 of two magnet steel described rivet connecting rod 3 being pressed on face mutually.
The quantity of described rivet connecting rod 3 determines that according to the hole of riveted joint usefulness and the quantity of set magnet steel 2 on each rotor 1 be generally 24, but be not limited to 24, evenly calibration is arranged in the inwall of rotor 1.
Described rivet 4 is non-magnetic metal material.
Described plastic plate 5 both sides are the inclined-plane, with two magnet steel 2 that face mutually that plastic plate 5 cooperates on inclined-plane with plastic plate 5 is arranged to anti-inclined-plane, be skewed after the installation and compress mutually.
The utility model compared with prior art, realized the object of the invention, overcome the weak point that prior art exists, owing to designed the rivet linkage, its calibration is arranged between the sheet magnet steel that rotor inner wall faces mutually, play every magnetic and fixedly dual-use function effect, the structure because this device employing metal and nonmetallic materials are combined into one has machinery and plasticity two specific characters, installs simple and convenient, realize non-conductive and magnetic conduction not, avoid eddy current and magnetic loss effectively.Need be on rotor or pressing plate tapping, processing is got up convenient, and has reduced manufacturing cost, has improved product quality, has prolonged useful life.
Description of drawings
Fig. 1 is a user mode schematic diagram of the present utility model;
Fig. 2 is part 3 schematic three dimensional views among Fig. 1;
Fig. 3 is the cutaway view of Fig. 2.
Identify among the figure: 1, rotor, 2, magnet steel, 3, the rivet connecting rod, 4, rivet, 5, the plastotype plate.
Embodiment
Accompanying drawing 1-3 is the utility model most preferred embodiment figure.
Further describe the content and the embodiment of detailed technology of the present utility model below in conjunction with accompanying drawing.
Fig. 1 represents that the utility model provides be equipped with the rivet linkage the permanent magnet motor rotor portion, among the figure, utilize epitrochanterian pair of rivet hole, strip calibration frock is fixed on carries out calibration in the rotor 1, this calibration frock is characterized as the spacing that strip has two screwed holes and diplopore and equates with rivet hole.By glue magnet steel 2 tentatively is fixed on the rotor 1 then, by riveting gun the two rivets 3 of composite rod are riveted on the rotor, allow the inclined-plane of plastotype plate 5 parts of the two rivets of composite rod push down the inclined-plane of adjacent two magnet steel, produce certain pressure magnet steel 2 is fixed on the rotor 1.
