Abstract
The invention discloses an external rotor assembly apparatus of an external rotor motor. The external rotor assembly apparatus comprises: an external rotor shell, a center hole of the external rotor shell and a rotor shaft. The rotor shaft is a stack class shaft comprising a large and a small size of concentric shafts. A large part shaft is a smooth circular shaft and is larger than the center hole of the external rotor shell. A small part shaft is smaller than the center hole of the external rotor shell. During assembling to the shaft, the small part shaft can pass through the center hole of the external rotor shell without any interference. After being extruded with a strong force into the shaft, the large part smooth shaft can form tight interference fit with the center hole of the external rotor shell. The small part shaft can not generate deformation. A group of the external rotor assembly apparatus of the external rotor motor with good concentricity, a high passing rate, low costs and a firm bonding force is formed. The external rotor assembly apparatus is suitable for being used in various kinds of alternating-current and direct-current external rotor motors.
Description
Technical field
The present invention relates to a kind of outer rotor motor, especially a kind of outer rotor motor external rotor assembly apparatus.
Background technology
Existing a kind of outer rotor motor external rotor assembly; Be with the straight body armature spindle of whole piece; With interference tight fit mode; Brute force squeezes into the outer rotor case centre bore; Thereby constitute one and combine firm external rotor assembly; Yet; This with the powerful extruding of the straight body armature spindle of whole piece; Reach through material deformation and to become the friction tight frame mode of interference with the outer rotor case centre bore; In process of production, also cause the deformation of armature spindle whole piece axle body simultaneously, thereby it is big to cause occurring external rotor assembly Concentricity tolerance; After wherein a part of external rotor assembly must pass through secondary rectification shaping processing; The qualified use of ability though another part external rotor assembly still also can't be qualified through secondary reshaping processing, can only be scrapped; Obviously; The Concentricity tolerance of this prior art external rotor assembly is big, the orthopedic processing of palpus secondary, and percent defective is high; The shortcoming that production cost is high will be improved.
Summary of the invention
The technical problem that the present invention will solve provides and a kind ofly can reach good concentricity, and qualification rate is high, and production cost is low, outer rotor motor external rotor assembly apparatus that again can strong bonded.
For solving the problems of the technologies described above; The present invention includes outer rotor case; Outer rotor case centre bore and armature spindle; Armature spindle is a repeatedly level axle of concentric big segment; Major part section axle body is smooth circular shaft, and the smooth circular shaft body of major part section diameter is bigger than outer rotor case center-hole diameter, and the smooth circular shaft body of major part section becomes the interference tight fit with the outer rotor case centre bore; Microcephaly's section axle body diameter is littler than outer transcapsidation body center-hole diameter, microcephaly's section axle body bearing set.
Change repeatedly level axle of big segment into through the straight body armature spindle of whole piece with prior art; In extrusion production external rotor assembly process; Because microcephaly's section axle body diameter is littler than outer rotor case center-hole diameter; Can have no to pass the outer rotor case centre bore with interfering; And place outside the scope of interference squeezing action force; Like this when the smooth circular shaft body of brute force extruding major part section interference fit is pressed into the outer rotor case centre bore; Even the contact-segment of smooth circular shaft body of major part section and outer rotor case centre bore is the generating material compressional deformation; But microcephaly's section axle body can not produce deformation; Thereby accurately guaranteed the concentricity of external rotor assembly after the extrusion modling; Basically must not make secondary and correct shaping processing; Just can reach the concentricity standard-required; Production efficiency and qualification rate have been improved greatly; Reduced production cost; And this size is a level extruding adhesion that becomes concentric circles interference tight fit to be produced with the outer rotor case centre bore repeatedly; Very solid and reliable; Be not subjected to temperature; Solvent; Factor affecting such as acid or alkali environment, thereby be adapted at various interchanges; Use in the direct current outer rotor motor external rotor assembly.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Referring to Fig. 1, Fig. 2 and Fig. 3; The present invention includes AC external rotor motor outer rotor case 1; Outer rotor case centre bore 2 and armature spindle; Armature spindle is a repeatedly level axle 3,4 of concentric big segment; Major part section axle body 3 is smooth circular shafts; Smooth circular shaft body 3 diameters of major part section are than the big 0.03mm of ac motor outer rotor case centre bore 2 diameters; Microcephaly's section axle body 4 diameters are than the little 1mm of ac motor outer rotor case centre bore 2 diameters; Microcephaly's section axle body 4 bearing set (not shown)s; When brute force is squeezed into spool; The smooth circular shaft body 3 of major part section becomes the interference tight fit with outer rotor case centre bore 2 in the deformation of contact-segment generating material; And because microcephaly's section axle body 4 is littler than outer rotor case centre bore 2; Can pass ac motor outer rotor case centre bore 2 without let or hindrance; And place outside the extrusion modling frock (not shown) active force scope; Deformation can not take place in whole section microcephaly's section axle body 4 in extrusion process; So; Once just form one group of good concentricity after the extruding; Qualification rate is high; Production cost is low, the AC external rotor motor outer rotor assembly apparatus of firm binding force.
Referring to Fig. 4; Fig. 5 and Fig. 6; The present invention includes direct current outer rotor motor outer rotor case 5; Outer rotor case centre bore 6 and armature spindle; Armature spindle is a repeatedly level axle 7 of concentric big segment; 8; Major part section axle body 7 is smooth circular shafts; Smooth circular shaft body 7 diameters of major part section are than the big 0.03mm of diameter of outer rotor case centre bore 6; Microcephaly's section axle body 8 diameters are stopped the little 4mm of centre bore 6 diameters than external rotor shell; Microcephaly's section axle body 8 bearing set (not shown)s; When brute force was squeezed into spool, the smooth circular shaft body 7 of major part section became the interference tight fit with outer rotor case centre bore 6 in the deformation of contact-segment generating material, so; Once just form one group of good concentricity after the extruding; Qualification rate is high, and production cost is low, the direct current outer rotor motor external rotor assembly apparatus of firm binding force.
