Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, a kind of Novel motor rotor assembly, comprise machine shaft 10, the middle part of described rotating shaft 10 is arranged with rotor core 20, described rotor core 20 is provided with armature winding 21, is arranged with commutator 30 in one end of rotating shaft 10, the arranged outside that rotating shaft 10 is positioned at commutator 30 has clutch shaft bearing 40, rotating shaft 10 other end is provided with the second bearing 50, rotating shaft 10 is also arranged with the fan blade 60 between the second bearing 50 and rotor core 20.
As shown in Figure 2 and Figure 3, fan blade 60 comprises the rotating disk 61 be connected with rotating shaft 10 and the multiple blades 62 be arranged on rotating disk 61 end face, described blade 62 circumferentially arranges, the shape of this blade 62 is trapezoidal, and there is the inner edge 62a be obliquely installed, be formed between each inner edge 62a and hold district 63, described armature winding 21 stretches into and to hold in district 63 and armature winding 21 is relative with the inner edge 62a of blade 62.
This motor rotor component adopts said structure, by the structure of fan blade 60 rational Design on Plane more, unchanged on the bulky single of fan blade 60, therefore, operating efficiency when fan blade 60 rotates is constant, but every fan leaf 62 has the inner edge 62a be obliquely installed, fan blade 60 entirety is made to form the accommodation district 63 caved inward from blade 62 to rotating disk 61, and the ledge being positioned at the armature winding 21 of fan blade 60 one end just stretches into this accommodation district 63, greatly save the space of motor internal, thus reduce the overall volume of motor, make the overall structure of motor compacter, decrease the energy consumption of motor simultaneously.
In addition, armature winding 21 stretches in the accommodation district 63 of fan blade 60 formation, blade 62 shape of fan blade 60 is corresponding to armature winding 21 external shape, gap between fan blade 60 and armature winding 21 obviously reduces, air in gap can arrange when rotating by fan blade 60 faster, and in rotation process, under the turning effort of fan blade 60, do not have air-flow and enter into gap, therefore, resistance when fan blade 60 rotates is less, the rotating speed of fan blade 60 comparatively evenly and and continue to rotate with higher rotating speed, make the radiating effect of motor better.
Further, the middle part of rotating disk 61 is provided with the branch sleeve 64 running through rotating disk 61 and in the middle part of branch sleeve 64, offers the through hole 64a that can be sheathed in rotating shaft 10, one end and branch sleeve 64 outer surface of described blade 62 are connected, because branch sleeve 64 runs through rotating disk 61, its length is greater than the thickness of rotating disk 61, therefore, branch sleeve 64 and the contact area of rotating shaft 10 are greater than the contact area that rotating disk 61 is directly connected with rotating shaft 10, make branch sleeve 64 more firm with the connection of rotating shaft 10, rock in rotating shaft 10 when avoiding fan blade 60 to rotate, thus ensure that the normal rotation of fan blade 60, simultaneously, too increase the frictional force between branch sleeve 64 and rotating shaft 10, fan blade 60 is not easily relatively rotated with rotating shaft 10, and every sheet blade 62 is all connected with branch sleeve 64, make the globality of fan blade 60 better, ensure that the intensity of whole fan blade 60.
As shown in Figure 4, described rotating shaft 10 outer surface is provided with the insulating case 70 be adjacent to rotating shaft 10, mounting groove 71 is offered in the middle part of described insulating case 70, the first radial depressions portion 72 and the second radial depressions portion 73 is offered respectively at the two ends of rotating shaft 10, the first ring-shaped platform 72a is formed between the first radial depressions portion 72 and insulating case 70, the second ring-shaped platform 73a is formed between the second radial depressions portion 73 and insulating case 70, described commutator 30 is sheathed in the first radial depressions portion 72 and commutator 30 one end and is against on the first ring-shaped platform 72a, fan blade 60 is sheathed in the second radial depressions portion 73 and branch sleeve 64 one end and is against on the second ring-shaped platform 73a.
After machine shaft 10 outer surface arranges insulating case 70, between rotating shaft 10 and insulating case 70, frictional force is larger, can not relatively rotate, and rotor core 20, commutator 30 and fan blade 60 are all fixedly mounted on insulating case 70, also rotor core 20 can be ensured, commutator 30, fan blade 60 is with rotating shaft 10 synchronous axial system, rotor core 20 is arranged in the mounting groove 71 of insulating case 70, rotor core 20 is not only adjacent to the outer surface of mounting groove 71, and the two ends of rotor core 20 are adjacent to two relative madial walls of mounting groove 71 respectively, add the contact area of insulating case 70 and rotor core 20, increase the frictional force between rotor core 20 and insulating case 70, prevent rotor core 20 and insulating case 70 from relatively rotating further, and commutator 30 to be arranged in the first radial depressions portion 72 and to be against on the first ring-shaped platform 72a, also can not move axially on insulating case 70 while making commutator 30 synchronous axial system, equally, fan blade 60 to be arranged in the second radial depressions portion 73 and to be against on the second ring-shaped platform 73a, make fan blade 60 with while rotating shaft 10 synchronous axial system also can not on insulating case 70 axial rotation.
Further, in order to make rotor core 20, commutator 30 and coordinate tightr between fan blade 60 with insulating case 70, the outer surface of insulating case 70 is provided with reticulate pattern, by arranging reticulate pattern, further increase rotor core 20, commutator 30 and the frictional force between fan blade 60 and insulating case 70, more effectively ensure that rotor core 20, commutator 30 and fan blade 60 are with rotating shaft 10 synchronous axial system.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
