Abstract
An outer rotor component of a motor comprises an outer rotor and bearings. The outer rotor consists of a rotor end, a shell, a magnetic shoe, a bearing housing and a rib which are integrally formed by means of injection molding, the rotor end, the rib and the bearing housing are plastic parts, the rib is disposed on the periphery of the bearing housing, and axially through radiating holes and a blade mounting hole are disposed at the rotor end. The bearing includes a first bearing and a second bearing which are mounted in the bearing housing. The outer rotor component of the motor has the advantages that the amount of parts is low, mounting working procedures are few, production cost is low, products are light, a radiating performance is good, and the like.
Description
Technical field
The present invention relates to motor component, particularly a kind of external rotor assembly of motor.
Background technology
The external rotor assembly of motor comprises external rotor and bearing, and external rotor is made up of rotor tip, casing, magnetic shoe and bearing chamber.In the prior art, above-mentioned rotor tip, casing, magnetic shoe and bearing chamber all are the independent respectively parts that are provided with, and adopt metal material to make mostly.The external rotor assembly of this form exists number of parts many, and installation procedure is many, and product quality is heavy, shortcomings such as production cost height.
Summary of the invention
The object of the invention in order to solve the problems referred to above that prior art exists, provides a kind of external rotor assembly of motor of new structure exactly.
To achieve these goals, the present invention has adopted following technical scheme: a kind of external rotor assembly of motor comprises external rotor and bearing;
Said external rotor is integrally formed through injection moulding by rotor tip, casing, magnetic shoe, bearing chamber and muscle, and rotor tip wherein, muscle, bearing chamber are working of plasticss; Muscle is arranged on the periphery of bearing chamber, and rotor tip is provided with the louvre and the fan blade installing hole of axial perforation;
Described bearing comprises the clutch shaft bearing and second bearing, and the clutch shaft bearing and second bearing are installed in the bearing chamber at interval.
The described clutch shaft bearing and second bearing vary in size, and described bearing chamber is inner small and outside big terraced structure, the less inboard that is installed in bearing chamber of clutch shaft bearing, and second bearing is installed in the outside of bearing chamber more greatly.
Described clutch shaft bearing is identical with the second bearing size, and described bearing chamber is the big reducing breakthrough form structures in middle little two ends, and the clutch shaft bearing and second bearing are installed in the two ends of bearing chamber respectively.
In described rotor tip is coated on casing.
Described rotor tip links to each other with casing is nested, outside the surface of casing is exposed to.
The external rotor assembly of motor of the present invention has following advantage and characteristics:
1, external rotor is integrally formed through injection moulding by rotor tip, casing, magnetic shoe, bearing chamber and muscle, has reduced installation procedure and part count, has reduced production cost;
2, with plastic material substituted metal material, further reduced production cost;
3, realize the product lightweight;
4, adopt integral molded plastic, guaranteed the axiality of bearing chamber and casing; The circularity of rotor also is guaranteed;
5, owing to be provided with muscle and louvre, satisfied the radiating requirements of motor effectively.

Fig. 2 is the bearing chamber among the present invention and the another kind of mounting means sketch map of bearing;
Fig. 3 is the rotor tip among the present invention and the another kind of annexation sketch map of casing.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Referring to Fig. 1, the external rotor assembly of motor of the present invention comprises external rotor and bearing.External rotor is integrally formed through injection moulding by rotor tip 1, casing 2, magnetic shoe 3, bearing chamber 4 and muscle 5, and rotor tip 1 wherein, muscle 5, bearing chamber 4 are working of plasticss; Muscle 5 is arranged on the periphery of bearing chamber 4, and rotor tip 1 is provided with the louvre 11 and fan blade installing hole 12 of axial perforation.
Bearing among the present invention comprises the clutch shaft bearing 6 and second bearing 7, and the clutch shaft bearing 6 and second bearing 7 are installed in the bearing chamber at interval.The clutch shaft bearing 6 and second bearing 7 can be to vary in size; When clutch shaft bearing 6 and second bearing 7 adopt the structure that varies in size; Bearing chamber 4 is designed to inner small and outside big terraced structure; Less clutch shaft bearing 6 is installed in the inboard of bearing chamber 4, and the second bigger bearing 7 is installed in the outside of bearing chamber 4.As shown in Figure 1.
If mould and die accuracy is higher; Clutch shaft bearing then also can adopt big or small identical structure shown in Figure 2 with second bearing; In this case, bearing chamber 4 can be designed to be the big reducing breakthrough form structure in little two ends, centre that the clutch shaft bearing 6 and second bearing 7 are installed in the two ends of bearing chamber respectively.
