Embodiment
Please refer to Fig. 1 and Fig. 2, Fig. 1 is the combination sketch map that the utlity model has the motor rotor 1 of the magnetite collar, and Fig. 2 is the element exploded perspective view of motor rotor 1.Motor rotor 1 has an axle center 10, one first collar 20, one second collar 40 and a plurality of magnetite 30.Axle center 10 has one first end 11, one second end 12 and a periphery 13.First end, 11, the second collars 40 that first collar 20 is linked in axle center 10 are linked in second end 12 in axle center 10, and a plurality of magnetites 30 then are arranged on the periphery 13.First collar 20 and second collar were located at 10 two ends, axle center in 40 minutes; And has identical structure in fact; Therefore can single mold and create by the mode of plastics or aluminium casting forming; The cost of reduce making, the mode of plastics or aluminium casting forming can be easy to first collar 20 and second collar 40 are processed any desired contour simultaneously, so can design its profile easily to reach and the magnetite 30 fixing effect that closely cooperates.
Please refer to Fig. 3, Fig. 3 is the wherein sketch map of a magnetite 30 of motor rotor 1.Magnetite 30 among the embodiment of the utility model is microscler sheets, but not as limit.As shown in Figure 3, magnetite 30 has one first end 31, one second end 32, one first cambered surface 33 and one second cambered surface 34.When magnetite 30 was arranged on the periphery 13 in axle center 10, first cambered surface 33 of magnetite 30 contacted with periphery 13 and is attached on the periphery 13, so first surface 33 also is a circular arc.
Please refer to Fig. 4, Fig. 4 is the sketch map of first collar 20 of motor rotor 1.First collar 20 has a plurality of equally spaced each other separation ribs 21, when first collar 20 is linked in first end 11 in axle center 10, these separation ribs 21 be against periphery 13 and and axle center 10 between form a plurality of storage tanks 22.Please in the lump with reference to also having a plurality of equally spaced each other separation ribs 41 on figure 2, the second collars 40, when second collar 40 is linked in second end 12 in axle center 10, these separation ribs 41 be against periphery 13 and and axle center 10 between form a plurality of storage tanks 42.
Assembling for ease; And make and to fit tightly between first collar 20 and second collar 40 and the magnetite 30 with fixing magnetite 30; After at first first collar 20 being linked in first end 11 in axle center 10; Form a plurality of storage tanks 22 between the separation rib 21 of first collar 20 and the periphery 13 in axle center 10, and equally spaced each other separation rib 21 makes that also the storage tank 22 that forms has identical distance.Then first end 31 of each magnetite 30 is extended to wherein in the corresponding storage tank 22, equally spaced storage tank 22 can guarantee that each magnetite 30 also equally spaced is arranged on the periphery 13 in axle center 10 each other.Then again second collar 40 is linked in second end 12 in axle center 10, and the separation rib 41 of second collar 40 and second end 32 of also ccontaining each magnetite 30 of periphery 13 formed equally spaced storage tanks 42.Can fast and accurately assemble motor rotor 1 like this, and each magnetite 30 is equally spaced distributed on axle center 10.On the motor rotor 1 of Fig. 1, can add upper bearing (metal) at two ends in addition and outside magnetite 30, coat a protective sleeve (figure does not show).In addition, because the assembling of motor rotor 1 need not add the program of heating, therefore can directly use the magnetite 30 that magnetizes in advance to assemble.And the storage tank 22 of first collar 20 also makes things convenient for 30 pieces of magnetite to put in, and does not need to use in addition tool to separate magnetite 30, effectively avoids magnetite 30 magnetic each other to inhale and scolds the difficulty that causes in the assembling.
Please refer to Fig. 5, Fig. 5 is the generalized section of motor rotor 1, and wherein Fig. 5 only shows first end 31 of first collar 20 and axle center 10, each magnetite 30, and second collar 40 is also similar with Fig. 5 with second end 32 of axle center 10, each magnetite 30.As shown in the figure; First cambered surface 33 of magnetite 30 contacts with the periphery 13 in axle center 10 and fits; And the storage tank 22 of first collar 20 has one the 3rd cambered surface 23 (like Fig. 4); And the 3rd cambered surface 23 with its second cambered surface 34 of ccontaining magnetite 30 have identical profile, therefore can completely be connected on the magnetite 30, as shown in Figure 5; Therefore when first end 31 of magnetite 30 extends to storage tank 22, first end 31 (second ends 32 of 40 complete coating magnetites 30 of second collar) that first collar 20 can complete coating magnetite 30.In the embodiment of the utility model, second cambered surface 34 of magnetite 30 is that both sides have the arc-shaped surface than deep camber, and is therefore not parallel each other with first cambered surface 33 (being positive arc surface), and a commentaries on classics phenomenon of such profile design can minimizing motor rotor 1.Because the contour feature of second cambered surface 34 of magnetite 30, make any storage tank 22 of first collar 20 can be greater than the wall thickness T2 of storage tank 22 central authorities, to reach complete coating at wall thickness T1 near separation rib 21 places.
In addition; In the embodiment of Fig. 1 and Fig. 2; Motor rotor 1 uniformly-spaced is arranged on the periphery 13 by 8 microscler sheet magnetites 30; But not as limit, magnetite 30 profiles of the motor rotor 1 of the utility model and quantity also can have other to change, and first collar 20 and second collar 40 that two ends are used for fixing magnetite 30 then also cooperate the quantity of magnetite 30 and profile to change.Under general application; Be uniformly-spaced to be arranged on the periphery 13 in axle center 10 between each magnetite 30 of motor rotor 1; But mode that also can unequal interval is arranged; First collar 20 and the separation rib 21,41 in second collar 40 that two ends are used for fixing magnetite 30 then have desired unequal interval storage tank 22,42 according to design, and each storage tank 22,42 all can cooperate the profile of each magnetite 30.
Motor rotor disclosed in the utility model; End in the axle center puts a magnetite collar earlier; The magnetite collar has separation rib and by separation rib and the formed a plurality of storage tanks of axle center one end, can conveniently the magnetite that magnetizes earlier one end be inserted in each storage tank like this.Then again another magnetite collar is enclosed within the axle center other end, a plurality of storage tanks of another magnetite collar are also distinguished the other end of ccontaining each magnetite simultaneously.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
