Embodiment
As Fig. 2, shown in Figure 3, it is the utility model first preferred embodiment, is made of wheel hub 1 and becket 2.
The central part of wheel hub 1 is provided with a central column 11, and this wheel hub 1 is into a ringwall and is looped around central column 11 all sides, the ringwall outer wall 12 of this wheel hub 1 can be established the blade 13 of several width of cloth directives, make this wheel hub 1 can form an impeller, the internal ring wall of this wheel hub 1 is to form joint portion 14, this joint portion 14 be can form matsurface or as shown in the figure parallel with 11 one-tenth of central columns to several ribs.
Becket 2 is to be integral in conjunction with a magnet ring 20 by its internal ring wall, and this becket 2 has one first end 21 and one second end 22, and this first end 21 can be established the ring lip 23 of protrusion, and this ring lip 23 can be for magnet ring 20 1 end butts; And the external diameter of second end 22 of this becket 2 is slightly larger than by wheel hub 1 joint portion 14 around formed internal diameter, and the external diameter of second end 22 of this becket 2 is also greater than the external diameter of first end 21.
As Fig. 4, shown in Figure 5, it is a combination situations of the present utility model, this becket 2 is after being combined with annular magnet 20, first end 21 of this becket 2 by its less external diameter contacted with the joint portion 14 of wheel hub 1 earlier, utilize the external force mode that urges that this becket 2 is pressed in this wheel hub 1 again, this becket 2 is all concealed in wheel hub 1, and make second end 22 of the big external diameter of becket 2 push against the joint portion 14 that is mounted in wheel hub 1, form the becket 2 that is combined with magnet ring 20 and can fixedly positioning in wheel hub 1.
As shown in Figure 6, when 11 one-tenth of the joint portion 14 of this wheel hub 1 and central columns parallel to rib, when this becket 2 is pressed in this housing 1, because of the rib of this formation joint portion 14 is to be made by plastic cement material, therefore the rib of this joint portion 14 has the advantage that is easy to be pushed against into distortion, and this becket 2 can push against the rib that is mounted in this joint portion 14 by second end 22 of big external diameter, form becket 2 more firm be combined in joint portion 14 in the wheel hub 1, and the section configuration of the rib of this joint portion 14 is to form semi-circular shape, or triangle rib 15 as shown in Figure 7, or arc concave shape rib 16 as shown in Figure 8.
As shown in Figure 9, it is second embodiment of becket of the present utility model, this becket 3 has one first end 31 and one second end 32 equally, this first end 31 has the ring lip 33 of protrusion, this ring lip 33 can be for the annular magnet 30 1 end butts of becket 3 inwall combinations, in the middle of present embodiment, the external diameter of this becket 3 is can form isometrical or its second end 32 is slightly larger than first end 31, and first end, 31 outer walls of this becket 3 are the chamferings that form the tool circular arc, the acute angle that the outer wall of this second end 32 then forms the right angle or outwards protrudes.
As shown in figure 10, when this becket 3 is combined in wheel hub 1 inwall by external force pressure, first end 31 of these becket 3 outer walls is because have the chamfering of circular arc, therefore, this becket 3 is can be easy to be pressed in wheel hub 1, and second end 32 of these becket 3 outer walls is owing to form right angle or acute angle, therefore, this right angle of this outer wall second end 32 or acute angle can form the 14 one-tenth location, joint portion that are embedded in this wheel hub 1, make this becket 3 in conjunction with magnet ring 30 have the more firm effect that combines with 1 of wheel hub.
As shown in figure 11, it is becket the 3rd embodiment of the present utility model, this becket 4 has one first end 41 and one second end 42 equally, this first end 41 has the ring lip 43 of protrusion, this ring lip 43 can be for the annular magnet 40 1 end butts of becket 4 inwall combinations, in the middle of present embodiment, outer wall second end 42 of this becket 4 is sharp keen burr 421 that formation one protrudes from becket 4 outer walls, and second end, 42 external diameters of the sharp keen burr 421 of this tool are slightly larger than joint portion 14 formed internal diameters in the wheel hub 1.
As shown in figure 12, when this becket 4 is combined in the joint portion 14 of wheel hub 1 by external force pressure, sharp keen burr 421 external diameters of this becket 4 outer walls second end 42 are because greater than joint portion 14 formed internal diameters in this wheel hub 1, therefore, the sharp keen burr 421 of this second end 42 are can form to be embedded in this joint portion 14, make this becket 4 in conjunction with magnet ring 40 have the more firm effect that combines with 1 of wheel hub.
The magnet ring fixture construction of rotor of the present utility model.Because this wheel hub is when moulding is made, needn't bury this becket of system again, and do not need in wheel hub, to establish buckling body yet, therefore, wheel hub manufacturing, the speed of production of this rotor can be accelerated, and this becket is that the inwall that can be easy to, promptly be bonded to this wheel hub is fixed, therefore, the manufacturing cost of this wheel hub can reduce, again and, when this becket that is combined with magnet ring is bonded to wheel hub, also firm combination can be arranged, therefore, should be when rotated by the formed rotor of wheel hub, also can reach rotation stable, balance, and can reduce the generation of noise.
The utility model can not depart under main spirit and the feature with other different forms enforcement.Therefore, above-mentioned preferred embodiment is just enumerated by way of example, and it should be considered as restriction of the present utility model.Scope of the present utility model is defined by claim, but not is defined by the content of specification.Person very, belong to the claim scope equivalence variation or to revise all be to fall within scope of the present utility model.
