Abstract
The invention relates to a magnetic steel piece deflection device of a servo motor. The magnetic steel piece deflection device comprises a rotating shaft (1) and magnetic steel pieces (3). The multiple magnetic steel pieces (3) are of a tile shape and connected end to end to form a row which is adhered to the outer circumference of the middle of the rotating shaft (1). A magnetic steel piece deflection sleeve (2) is connected to the outside circumference of the middle of the rotating shaft (1) in a sleeved mode. Notches (6) are formed in the positions, corresponding to the magnetic steel pieces (3), of the magnetic steel piece deflection sleeve (2). One side of each notch (6) is provided with a linear edge, and the other side of each notch (6) is provided with a continuous step edge (4) which is formed by sequentially connecting a plurality of steps. The magnetic steel pieces (3) are tightly attached to the corresponding steps one to one. The magnetic steel piece deflection device is simple in structure, and efficiency and angle accuracy of magnetic steel piece deflection installation are greatly improved in the magnetic steel piece deflection process.
Description
Technical field
The present invention relates to electric machine structure field, particularly relate to a kind of magnet steel arrangement for deflecting of servomotor.
Background technology
In servomotor technical field, often can run into a kind of phenomenon, after motor has assembled; rotor is because the effect of motor stator teeth groove; rotate not smooth, common alleged slot effect namely, excessive slot effect can badly influence the rotation precision of motor.In order to reduce slot effect, the solution that technical staff often takes is that magnetic pole phase countershaft has certain angle, the mode of namely magnetic pole deflection.But the magnet steel of One's name is legion is installed to certain angle and be arranged in order that to paste rotating shaft be the work of wasting time and energy very much, and when pasting, be easy to occur that stickup is inaccurate, the inconsistent problem of deflection angle is urgent problem so how to improve sticking efficiency and the accuracy of magnetic pole deflection.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of magnet steel arrangement for deflecting of servomotor, simple in structure, the efficiency that while greatly having improved magnetic pole deflection, magnet steel deflection is installed and the accuracy of angle.
The technical solution adopted for the present invention to solve the technical problems is: the magnet steel arrangement for deflecting that a kind of servomotor is provided, comprise rotating shaft and magnet steel, described magnet steel is tile, there are some, end to end being on the middle part periphery that a row sticks on rotating shaft, described outside, rotating shaft middle part disc is socketed with magnet steel deflection cover, this magnet steel deflection puts the position corresponding with magnet steel and has breach, one side of this breach is straight line, another side is the continuous step limit that has several steps to be in turn connected to form, and described magnet steel is close to layout one by one with corresponding step.
The two ends, middle part of described rotating shaft are arranged symmetrically with limited location boss, and this positive stop lug boss withstands with the magnet steel that is positioned at two ends.
The difference of the central angle on described continuous step limit between adjacent step and breach straight line equates.
The internal diameter size of described magnet steel is identical with the middle part outside dimension of rotating shaft.
The quantity of described magnet steel should be not more than the quantity of topping bar in continuous step limit, and this quantity is not more than 4.
Described magnet steel deflection cover aluminium alloy or copper alloy are made.
beneficial effect
The present invention relates to a kind of magnet steel arrangement for deflecting of servomotor, simple in structure, when install magnet steel on the continuous step limit that utilizes magnet steel deflection to overlap, carry out spacing, guaranteed the accuracy of magnet steel deflection angle, treat after row's magnet steel installs, magnet steel deflection cover to be taken off, the first row magnet steel of just can take is pasted remaining all magnet steel as benchmark, has greatly improved the installation effectiveness of magnet steel.
Accompanying drawing explanation
Fig. 1 is that master of the present invention looks sectional structure chart;
Fig. 2 is the end view of magnet steel deflection cover of the present invention;
Fig. 3 is the front view of magnet steel deflection cover of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As Figure 1-3, embodiments of the present invention relate to a kind of magnet steel arrangement for deflecting of servomotor, comprise rotating shaft 1 and magnet steel 3, described magnet steel 3 is tile, there are some, end to end being on the middle part periphery that a row sticks on rotating shaft 1, outside described rotating shaft 1 middle part, disc is socketed with magnet steel deflection cover 2, on this magnet steel deflection cover 2, the position corresponding with magnet steel 3 has breach 6, one side of this breach 6 is straight line, another side is the continuous step limit 4 that has several steps to be in turn connected to form, and described magnet steel 3 is close to layout one by one with corresponding step.
The two ends, middle part of described rotating shaft 1 are arranged symmetrically with limited location boss 5, and this positive stop lug boss 5 withstands with the magnet steel 3 that is positioned at two ends.
The difference of the central angle on described continuous step limit 4 between adjacent step and breach 6 straight lines equates.
The internal diameter size of described magnet steel 3 is identical with the middle part outside dimension of rotating shaft 1.
The quantity of described magnet steel 3 should be not more than the quantity of topping bar in continuous step limit 4, and this quantity is not more than 4.
Described magnet steel deflection cover 2 is for to make without the material of magnetic force, as aluminium alloy or copper alloy, prevent and magnet steel 3 between produce suction power.
During use, first magnet steel deflection cover 2 is socketed in to the outside of rotating shaft 1, align with positive stop lug boss 5 in its two ends, then the step of being close on continuous step limit 4 is pasted in a row by the magnet steel of equal number 3 successively, treat after row's magnet steel 3 installs, magnet steel deflection cover 2 to be taken off, the first row magnet steel 3 of just can take is pasted and is left all magnet steel 3 as benchmark.
Do not need to measure the deflection angle of every a slice magnet steel 3, corresponding different model, it is just passable that the product of different size only need to be changed different magnet steel deflection covers 2, greatly improved the installation effectiveness of magnet steel.
