Described rotor core 31 has rivet patchhole 63 making progress in the week of rotor core 31 between the adjacent magnet 32,32.In other words, described the 1st line segment S1 and described the 2nd line segment S2 be the center by rivet patchhole 63 respectively, and magnet 32 and does not intersect with the 1st line segment S1 and the 2nd line segment S2 between the 1st line segment S1 and the 2nd line segment S2.Rivet 33 is inserted in this rivet patchhole 63.
As shown in Figure 4, described the 1st caulking part 51 and described the 2nd caulking part 52 have length direction 51a, 52a respectively.The length direction 52a of the length direction 51a of the 1st caulking part 51 and the 2nd caulking part 52 is towards different directions.This place says that " length direction " refers to the direction of the longest direction (for example long limit or major diameter) by the center of caulking part along caulking part.
That is, described the 1st caulking part 51 and described the 2nd caulking part 52 are respectively rectangles.The length direction of the length direction of the 1st caulking part 51 and the 2nd caulking part 52 is towards different directions.
The length direction 51a of described the 1st caulking part 51 is radially consistent with rotor core 31.The length direction 52a of described the 2nd caulking part 52 is with respect to the radial skew of rotor core 31.
Specifically, the end 521 of the length direction 52a of described the 2nd caulking part 52 is positioned at the downstream of the direction of rotation R of rotor core 31.The other end 522 of the length direction 52a of the 2nd caulking part 52 is positioned at the upstream side of the direction of rotation R of rotor core 31.
And, the length direction 52a of the 2nd caulking part 52 so that a described end 521 be positioned at than the mode of described the other end 522 by the position of the radially inner side of rotor core 31, with respect to the radial skew of rotor core 31.
Observe from the central shaft 31a direction of rotor core 31, described the 1st caulking part 51 intersects with the straight line L of the central shaft 31a of the center that is connected magnet 32 and rotor core 31 with described the 2nd caulking part 52.Specifically, the center of the center of the 1st caulking part 51 and the 2nd caulking part 52 and described straight line L intersect.
The length direction 51a of described the 1st caulking part 51 is consistent with described straight line L.The length direction 52a of described the 2nd caulking part 52 tilts with respect to described straight line L.One end 521 of the 2nd caulking part 52 be positioned at than the center by the 2nd caulking part 52 and with the cross line C of the described straight line L-orthogonal position by the radially inner side of rotor core 31.The other end 522 of the 2nd caulking part 52 is positioned at the position by the radial outside of rotor core 31 than described cross line C.
And, described the 1st caulking part 51 is positioned at the radially inner side of rotor core 31 with respect to magnet 32, namely, the 1st caulking part 51 is positioned at central shaft 31a with magnet 32 and rotor core 31 and couples together the delta-shaped region that forms, magnet 32 and the 1st caulking part 51 are overlapping diametrically, and the length direction 51a of the 1st caulking part 51 is different with the length direction 52a of the 2nd caulking part 52, thereby the riveting intensity of rotor core 31 strengthens at both direction, can improve intensity, and the length direction 52a that can make the length direction 51a of the 1st caulking part 51 and the 2nd caulking part 52 along the magnetic flux circulation towards.
Therefore, can utilize described the 1st caulking part 51 and the 2nd caulking part 52 Motionless electromagnetic steel plate securely on both direction, and the torque that increases rotor core 31, and then raise the efficiency, and do not hinder the circulation of magnetic flux.
If suppose to make the 1st caulking part 51 in the central shaft 31a with the zone between the adjacent magnet 32 and rotor core 31 couples together the zone that forms, the magnetic flux that flows through in the 2nd caulking part 52 residing positions in the outside of the 1st caulking part 51 and magnet 32 towards roughly the same then.Therefore, if make the length direction 52a of the length direction 51a of the 1st caulking part 51 and the 2nd caulking part 52 along the circulating direction of the magnetic flux of roughly the same direction, then the length direction 52a of the length direction 51a of the 1st caulking part 51 and the 2nd caulking part 52 become identical towards, intensity weakens.
Therefore, can utilize smaller the 1st and the 2nd caulking part 51,52 of area to realize the raising of intensity of rotor core 31 and the decline of the rotor performance that prevents relevant torque and efficient simultaneously.
Relative therewith, the caulking part in past is circular, and this circle does not have directivity, in order to increase the intensity based on the rotor core of caulking part, must need to increase circular whole.And if it is whole to increase circle, then caulking part hinders the circulation of the magnetic flux of magnet, and the rotor performance of relevant torque or efficient descends.Like this, there is not the caulking part of the circle of directivity can not realize the raising of intensity of rotor core and the decline of the rotor performance that prevents relevant torque and efficient simultaneously.
In addition, the length direction 51a of described the 1st caulking part 51 is radially consistent with rotor core 31, thus the length direction 51a of the 1st caulking part 51 towards the circulation that becomes the magnetic flux that does not hinder magnet 32 towards.That is, in Fig. 4, represent the circulation of the magnetic flux of described magnet 32 with arrow B 1, the length direction 51a of the 1st caulking part 51 along the direction B1 of the circulation of the magnetic flux of magnet 32 and with its almost parallel.
On the other hand, the length direction 52a of described the 2nd caulking part 52 is with respect to the radial skew of rotor core 31, thus become length direction 51a with the 1st caulking part 51 different towards, can improve the intensity of rotor core 31.
In addition, the width of the Outboard Sections of the radial outside of the magnet 32 in the described rotor core 31 is greater than the width of magnet 32, thereby no matter which direction the length direction 52a of the 2nd caulking part 52 is, the magnetic flux of the magnet 32 that passes through at the Outboard Sections of rotor core 31 all is not subject to the influence of the 2nd caulking part 52.
One end 521 of described the 2nd caulking part 52 is positioned at than the position by the radially inner side of rotor core 31, the other end 522 of the 2nd caulking part 52, thus the length direction 52a of the 2nd caulking part 52 towards become do not hinder from the circulation of the magnetic flux of stator side towards.Therefore, the influence from the magnetic flux of stator side based on the 2nd caulking part 52 can be reduced, the decline of the rotor performance of relevant torque and efficient can be further prevented.In Fig. 4, represent circulation from the magnetic flux of stator side with arrow B 2, the length direction 52a of the 2nd caulking part 52 along from the direction B2 of the circulation of the magnetic flux of stator side and with its almost parallel.
And, observe from the central shaft 31a direction of rotor core 31, described the 1st caulking part 51 intersects with the straight line L of the central shaft 31a of the center that is connected magnet 32 and rotor core 31 with described the 2nd caulking part 52, thereby can further reduce influence based on the 1st and the 2nd caulking part 51,52 magnetic flux, can further prevent the decline of the rotor performance of relevant torque and efficient.
The center of the center of especially described the 1st caulking part 51 and described the 2nd caulking part 52 and described straight line L intersect, thereby can further reduce influence based on the 1st and the 2nd caulking part 51,52 magnetic flux, can further prevent the decline of the rotor performance of relevant torque and efficient.
In addition, described rotor core 31 is leaning on the position of the radially inner side of rotor core 31 to have through hole 61 than described the 1st caulking part 51, thereby through hole 61 does not hinder the circulation of the magnetic flux of magnet 32.
In addition, described rotor core 31 has rivet patchhole 63 making progress in the week of described rotor core 31 between the adjacent magnet 32,32, thereby rivet patchhole 63 does not hinder the circulation of the magnetic flux of magnet 32.
According to the compressor of said structure, owing to have above-mentioned rotor 30, thereby can realize the raising of intensity simultaneously and prevent that performance from descending.
In addition, the utility model is not limited to above-mentioned execution mode.For example, also can make the quantity of the 1st caulking part and the 2nd caulking part surpass 2 times of quantity of magnet, can further improve the intensity of rotor core.
