Below, with reference to accompanying drawing, embodiment is described.In addition, the embodiment shown in below does not play any restriction effect to the summary of the invention described in claim.In addition, the solution that the full content of the formation below represented by embodiment is not limited to as the invention described in claim is necessary.
Refer to Fig. 1 and Fig. 2, the vertical view of the outer rotor iron core that Fig. 1 provides for the embodiment of the present invention; Fig. 2 is the cutaway view of Fig. 1 along A-A line.
The outer rotor iron core 100 that the embodiment of the present invention provides comprises first end tooth section, intermediate channel section and the second end tooth section vertically successively.Focusing on of the embodiment of the present invention, outer rotor iron core is overrided to form by a kind of external rotor punching, and in order to ensure only to adopt a kind of external rotor punching also can meet the demands, the embodiment of the present invention has done following adjustment.
Multiple punching teeth that external rotor punching comprises punching body 101 and is evenly arranged on the inwall of punching body 101.For the ease of distinguishing punching tooth, the punching tooth of the present embodiment to first end tooth section, intermediate channel section and the second end tooth section renames, and the punching tooth laminating into the external rotor punching of first end tooth section and the second end tooth section is end face internal tooth 102; Internal tooth 103 centered by the punching tooth laminating into the external rotor punching of intermediate channel section, center internal tooth 103 and end face internal tooth 102 are staggered, make to form location notch 105 between the end face internal tooth of the end face internal tooth of first end tooth section and the second end tooth section, location notch 105 is for being engaged (as shown in Figure 3) with the iron core external tooth 202 of internal rotor iron core 200.
Outer rotor iron core 100 provided by the invention, be overrided to form by a kind of external rotor punching, when first end tooth section has laminated, external rotor punching is rotated to an angle, intermediate channel section is laminated, and then laminates the second end tooth section, ensure the second end tooth section and the same angle of first end tooth section, the i.e. punching tooth one_to_one corresponding of the second end tooth section and first end tooth section, and be located along the same line.Outer rotor iron core 100 of the present invention is overrided to form by a kind of external rotor punching, saves one set of die, and the operation of punching simultaneously also reduces together, and the continuity of punching process increases, and improves production efficiency.The present invention is staggered due to center internal tooth 103 and end face internal tooth 102, so outer rotor iron core 100 can produce the effect of twice punching number of teeth amount, therefore can the punching number of teeth amount of corresponding minimizing external rotor punching, make the structure of inner and outer rotors core stamping relatively simple (inside and outside number of teeth amount reduces), the maintenance cost of mould also reduces.
In the present invention one specific embodiment, the angle that center internal tooth 103 and end face internal tooth 102 stagger is the half of angle between adjacent two punching teeth, and namely center internal tooth 103 staggers to the centre of adjacent two end face internal tooths 102.For punching tooth for four of being evenly arranged along the circumference of external rotor punching, then the angle of arbitrary neighborhood two punching teeth is 90 °; Accordingly, the angle that center internal tooth 103 and end face internal tooth 102 stagger is 45 °, and namely center internal tooth 103 is positioned at the centre of adjacent two end face internal tooths 102.
In the present invention one specific embodiment, the outer wall of external rotor punching is evenly provided with multiple for locating the magnet positioning tooth 104 with fixed permanent magnet, the quantity of magnet positioning tooth 104 is 2n times of the quantity of punching tooth, n >=1, and is integer.In the present embodiment, n is preferably 1.It is four for punching tooth, magnet positioning tooth 104 is 8, certainly also can be other quantity, as 16,32 etc., can ensure like this center internal tooth 103 and end face internal tooth 102 stagger respective angles time, the magnet positioning tooth 104 on the outer wall of each external rotor punching can be arranged on same straight line.
Further, each punching tooth is all to the magnet positioning tooth 104 that should be had to be located along the same line with it.It should be noted that, also can there is not corresponding relation with punching tooth in magnet positioning tooth 104.
Refer to Fig. 3-Fig. 7, the front view of the internal rotor iron core that Fig. 3 provides for the embodiment of the present invention; The vertical view of the internal rotor iron core that Fig. 4 provides for the embodiment of the present invention; Fig. 5 is the cutaway view of Fig. 4 along B-B line; The vertical view of the damping rotor that Fig. 6 provides for the embodiment of the present invention; Fig. 7 is the cutaway view of Fig. 6 along C-C line.
The embodiment of the invention also discloses a kind of damping rotor, comprise outer rotor iron core 100 and internal rotor iron core 200, multiple iron core external tooths 202 that internal rotor iron core 200 comprises internal rotor iron core body 201 and is arranged on internal rotor iron core body 201 outer wall.The axle center place of internal rotor iron core body 201 offers iron core axis hole 203, for wearing armature spindle.As shown in Figure 3, the two ends of internal rotor iron core 200 do not have iron core external tooth 202, and oil-feed mid portion has iron core external tooth 202, and therefore internal rotor iron core 200 needs to laminate formation by two kinds of rotor punchings.
Iron core external tooth 202 is engaged with the location notch 105 of outer rotor iron core 100, forms multiple staggered space, for injecting elastomeric material in multiple staggered space, makes inner and outer rotors iron core be combined into an entirety.The even adhesive permanent magnetism body of outer rotor iron core excircle, forms a complete rotor (i.e. damping rotor) by injection moulding.Owing to having rubber filling in damping rotor, rubber has good flexible and retractility, and the vibration produced in damping rotor turns process can be effectively reduced.
Of the present inventionly focus on, outer rotor iron core 100 is as above outer rotor iron core disclosed in embodiment.Owing to having above-mentioned outer rotor iron core, therefore this damping rotor has all technique effects of above-mentioned outer rotor iron core equally, does not repeat them here herein.
Further, iron core external tooth 202 is identical with the quantity of location notch 105, and one_to_one corresponding occlusion.Certainly, the quantity of iron core external tooth 202 also can more than the quantity of location notch 105, and the present invention does not limit.
The embodiment of the invention also discloses a kind of motor adopting above-mentioned damping rotor, owing to having above-mentioned damping rotor, therefore this motor has all technique effects of above-mentioned damping rotor equally, does not repeat them here herein.
