Abstract
The utility model discloses an electric generator rotor structure for an automobile, which comprises a rotating shaft, a magnet yoke and a driving-end claw pole part, wherein the driving-end claw pole part is formed by connecting a driving-end claw pole and a steel fan into a whole; the driving-end claw pole is provided with an extending cylinder section matched with the rotating shaft; the steel fan consists of a circular ring and symmetrical fan blades on the circular ring; and an inner circular surface of the circular ring of the steel fan adapts to the outer circular surface of the extending cylinder section of the driving-end claw pole. By adopting the way, the electric generator rotor structure for the automobile leads the driving-end claw pole part to omit a bushing part, ensures the driving-end claw pole and the steel fan to form an integral structure, avoids the unsafe factor of relative rotation among the parts of the driving-end claw pole part when an electric generator is in work, leads the vertical degree between the driving-end claw pole part and a bearing inner ring contact end surface to meet the requirement, and prolongs the service life of a rotor bearing.
Description
Technical field
The utility model relates to electric generators for automobile, especially relates to a kind of electric generators for automobile rotor structure.
Background technology
The electric generators for automobile rotor structure comprises rotating shaft, yoke, drive end pawl utmost point portion, electricity lid end pawl utmost point portion and slip ring, electricity lid end pawl utmost point portion comprises the electricity lid end pawl utmost point and plastic fan, drive end pawl utmost point portion comprises the drive end pawl utmost point, steel fan and lining, the steel fan of drive end pawl utmost point portion is between the drive end pawl utmost point and lining, the end face of the drive end pawl utmost point is the plane of fitting with the steel fan, the one side of lining is fitted with the steel fan, when assembling, the another side of lining needs contact with bearing inner race, such structure, the perpendicularity of the end face that contacts with bearing inner race of lining is had relatively high expectations, even so, because pressure-riveting process and rigging error, the end face squareness that lining is contacted with bearing inner race is bigger than normal, can cause descend the useful life of rotor bearing, there is the unsafe factor that relatively rotates in electric generators for automobile rotor high speed rotating when work between the part of drive end pawl utmost point portion in addition.
The utility model content
Technical problem to be solved in the utility model is: a kind of electric generators for automobile rotor structure is provided, this kind electric generators for automobile rotor structure can prolong the useful life of rotor bearing, the unsafe factor that relatively rotates between the part of drive end pawl utmost point portion when stopping generator work.
Solve this technical problem, the technical solution of the utility model is: a kind of electric generators for automobile rotor structure, comprise rotating shaft, yoke and drive end pawl utmost point portion, described drive end pawl utmost point portion is fused by the drive end pawl utmost point and steel fan and forms, described drive end pawl has the cylindrical section that stretches out that cooperates with rotating shaft, described steel fan is made up of the flabellum of the symmetry on annulus and the annulus, and the cylindrical section periphery that stretches out of the inner headed face of the annulus of described steel fan and the drive end pawl utmost point adapts.
Described steel fan and drive end pawl are extremely integrally welded.
A kind of electric generators for automobile rotor structure of the utility model is adopted in such a way, the lining part has been saved in drive end pawl utmost point portion, the drive end pawl utmost point and steel fan are overall structure, the unsafe factor that has relatively rotated between the part of drive end pawl utmost point portion when having stopped generator work, the perpendicularity that can make drive end pawl utmost point portion contact end face with bearing inner race meets the requirements, and can prolong the useful life of rotor bearing.
Description of drawings
Below in conjunction with accompanying drawing a kind of electric generators for automobile rotor structure of the utility model is done explanation in further detail;
Fig. 1 is the schematic diagram of a kind of electric generators for automobile rotor structure of the utility model;
In Fig. 1,1, rotating shaft; 2, steel fan; 3, the drive end pawl utmost point; 4, yoke; 5, plastic fan; 6, the electricity lid end pawl utmost point; 7, slip ring.
Embodiment
As shown in Figure 1, the electric generators for automobile rotor structure comprises rotating shaft 1, yoke 4, drive end pawl utmost point portion, electricity lid end pawl utmost point portion and slip ring 7, electricity lid end pawl utmost point portion comprises the electricity lid end pawl utmost point 6 and plastic fan 5, drive end pawl utmost point portion is by the drive end pawl utmost point 3 and 2 integrally welded compositions of steel fan, the drive end pawl utmost point 3 has the cylindrical section that stretches out that cooperates with rotating shaft 1, steel fan 2 is made up of the flabellum of the symmetry on annulus and the annulus, and the cylindrical section periphery that stretches out of the inner headed face of the annulus of steel fan 2 and the drive end pawl utmost point 3 adapts.Like this, the lining part can be saved in drive end pawl utmost point portion, the drive end pawl utmost point and steel fan are overall structure, the unsafe factor that has relatively rotated between the part of drive end pawl utmost point portion when having stopped generator work, the perpendicularity that can make drive end pawl utmost point portion contact end face with bearing inner race meets the requirements, and can prolong the useful life of rotor bearing.
