Abstract
The utility model provides an electrical vehicle motor rotor composed of the inner and outer rotor rings. The inner rotor ring is installed with interference fit on the inner hole of the outer rotor ring. The wall thickness of the inner rotor ring is 3-12 mm and the outer diameter phi is 80-500 mm. The wall thickness of the outer rotor ring is 1-6 mm. The inner hole diameter matches the outer diameter of the rotor.
Description
Technical field
The utility model relates to motor vehicle, is meant a kind of electric vehicle motor rotor that is used as the combining structure of electric motor car power set especially.
Background technology
The rotor of electric motor car power motor generally adopts all steel integrative-structure form at present.Though all steel integrative-structure rotor can satisfy the needs of power motor running, because its manufacturing forms by molten steel casting, exist and water that foundry goods is yielding, hardness is high, the big waste material of processing and forming amount and the high defective of processing cost, therefore influenced further promoting the use of of all steel integrative-structure electric motor car power motor.
Summary of the invention
Technical problem to be solved in the utility model just is to overcome the defective of all steel integrative-structure electric motor car power motor, provide a kind of by sheet metal through rotor inner ring that the sweating heat shaping is rolled into and the electric vehicle motor rotor after curved circle welding, made through the rotor outer ring combination that the mould roll extrusion forms again by sheet metal as the combining structure of electric motor car power set.The electric vehicle motor rotor of combining structure of the present utility model is constituted by rotor inner ring and rotor outer ring, and the rotor inner ring is installed on rotor outer ring endoporus with interference fit.The wall thickness of rotor inner ring is 3-12mm, external diameter φ 80-500mm; To be 3-12mm strip sheet metal weld behind the pulleying circle makes through overheated shaping again by thickness.The wall thickness of rotor outer ring is 1-6mm, and diameter of bore matches with rotor inner ring external diameter, and the rotor outer ring is that the sheet metal of 1-6mm welds behind curved circle and made by the mould roll extrusion by thickness.The rotor inner ring is installed on outside the endoporus of rotor outer ring divided by interference fit, also can perhaps adopt other technology mode the rotor inner ring to be installed on the endoporus of rotor outer ring by the rivet welding process Installation in the endoporus of rotor outer ring.The rotor inner ring and the rotor outer ring of the rotor after assembling are integrated, and through adjusting and directly use in motor production of processing, make the production cost of rotor reduce about 25% slightly.
Advantage of the present utility model just is to adopt the electric vehicle motor rotor of combining structure, has avoided casting manufacturing process loaded down with trivial details, that fall behind.The electric vehicle motor rotor manufacturing process of the utility model combining structure is simple, labour intensity reduces relatively, and the rotor that assembling is made has been saved manufactured materials through adjusting need not reprocess substantially slightly, has reduced processing cost.Compare production cost with casting process and reduce about 25%.Therefore the electric vehicle motor rotor of combining structure of the present utility model has the vast market promotion prospect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further,
Fig. 1 is the structural representation of existing all steel integrative-structure electric motor car power motor rotor;
Fig. 2 is the structural representation of the electric vehicle motor rotor of the utility model combining structure;
Fig. 3 is the rotor inner ring schematic diagram of the electric vehicle motor rotor of the utility model combining structure;
Fig. 4 is the rotor outer ring schematic diagram of the electric vehicle motor rotor of the utility model combining structure.
With reference to Fig. 1, existing all steel integrative-structure electric motor car power motor rotor is as a whole, adopts casting process to make.
With reference to Fig. 2, Fig. 3, Fig. 4, the rotor outer ring that the rotor inner ring that the electric vehicle motor rotor of the utility model combining structure is represented by Fig. 3 and Fig. 4 represent constitutes.As Fig. 2 for the rotor inner ring being installed on the rotor that forms one behind the endoporus of rotor outer ring.
Embodiment
Below be an embodiment of the present utility model, the actual use of the present utility model is not limited to embodiment.
Embodiment 1, the electric vehicle motor rotor of combining structure
Adopt the electric vehicle motor rotor of the utility model combining structure, rotor is constituted by rotor inner ring and rotor outer ring, and the rotor inner ring is installed on rotor outer ring endoporus with interference fit.The wall thickness of rotor inner ring is 8mm, external diameter φ 225mm; To be 8mm strip sheet metal weld behind the pulleying circle makes through overheated shaping again by thickness.The wall thickness of rotor outer ring is 4mm, and diameter of bore matches with rotor inner ring external diameter, and the rotor outer ring is that the sheet metal of 4mm welds behind curved circle and made by the mould roll extrusion by thickness.The rotor inner ring and the rotor outer ring of the rotor after assembling are integrated, and directly use in motor is produced through adjusting promptly slightly, and operating position is good.The rotor production cost reduces about 25%.
Claims (3)
1, a kind of electric vehicle motor rotor is characterized in that being constituted by rotor inner ring and rotor outer ring, and the rotor inner ring is installed on rotor outer ring endoporus with interference fit.
2, electric vehicle motor rotor according to claim 1, the wall thickness that it is characterized in that the rotor inner ring is 3-12mm, and the wall thickness of external diameter φ 80-500mm rotor outer ring is 1-6mm, and diameter of bore matches with rotor inner ring external diameter.
