Abstract
The utility model relates to automobile generators and provides an automobile generator rotor. The bottom of a gap in a claw of a claw pole on an end of a collecting ring is in an arc-shaped transition form. And two grooves are arranged in a surface of the claw pole on the end of the collecting ring neighboring to a fan blade. The grooves are enclosed by the fan blade and form through-hole type thread holes. Orifices on one ends of the thread holes are arranged in the bottom of the gap in the claw while orifices on the other ends of the thread holes are neighboring to an installation shaft. When in assembling, a lead bypasses the gap in the claw of the claw pole and is clipped in the grooves. Then, the fan blade is installed to fix the lead in the thread holes formed by enclosing the grooves. No hole punching is needed and no lead fixing structure needs to be added between the collecting ring and the fan blade. Thus, the assembly is convenient. Compared with a prior hole punching technique, the thread holes in the utility model has lower requirements in precision, and no external hole punching procedure needs to be added. The thread holes are easier to form in punch and forge molding. And waster caused by deformation of punched holes can be avoided. Thus, the processing of the claw pole and the fan blade can be simplified.
Description
Technical field
The utility model relates to automobile current generator, especially a kind of automobile generator rotor.
Background technology
The rotor of automobile current generator is made up of coil windings, yoke, the pawl utmost point, installation shaft, collector ring; Wherein yoke is claimed skeleton again; Coil windings is wrapped on the skeleton, and the two pawl utmost points are oppositely arranged, and coil windings and skeleton are installed in the two pawl utmost points and surround in the formation chamber; And extremely make each pawl magnetic poles of the pawl utmost point through the magnetization pawl; The excitation mechanism that is made up of coil windings, skeleton, the pawl utmost point is installed on the generator housing through installation shaft, and collector ring is sleeved on the installation shaft of rear end, and coil windings forms electrical connection through collector ring and brush.
In order to improve the heat dispersion of generator, present automobile current generator is provided with internal fan usually, promptly a flabellum is installed at the pawl of an adjacent end with collector ring on extremely.The correspondence position of the pawl utmost point and flabellum is provided with through hole respectively and constitutes through wires hole, and lead-in wire directly passes the pawl utmost point by the pawl utmost point one side through through wires hole and is connected with collector ring then with flabellum, but there are two problems in this mode: the difficulty of processing that has increased the pawl utmost point and flabellum; Lead-in wire perforation inconvenience; Lead-in wire passes the applying in order to guarantee to go between behind the through wires hole, between collector ring and flabellum, needs to increase the fixed structure of lead-in wire, therefore assembles loaded down with trivial details.
The utility model content
The utility model technical problem to be solved provides a kind of pawl utmost point and flabellum processing and automobile generator rotor easy to assembly simplified.
The utility model solves the technical scheme that its technical problem adopted: automobile generator rotor; Comprise installation shaft, the pawl utmost point, collector ring, be fixed on the flabellum that collector ring one end pawl is extremely gone up; The inter-claw space bottom of the said collector ring one end pawl utmost point is an arc transition; And the adjacent surface of the collector ring one end pawl utmost point and flabellum is provided with two grooves, constitutes through hole type through wires hole by the flabellum closed pockets, and aperture and installation shaft that the aperture of through wires hole one end is positioned at inter-claw space bottom, the other end are adjacent.
Further, said groove is the straight-line groove along pawl utmost point radial arrangement.
Further, the axis hole periphery of flabellum is provided with and the groove corresponding opening, and the groove that is exposed by opening part constitutes the through wires hole aperture adjacent with installation shaft.
The beneficial effect of the utility model is: during assembling; At first lead-in wire is walked around the inter-claw space of the pawl utmost point and snap in the groove; Then flabellum being installed in pawl extremely goes up; Thereby lead-in wire is fixed in the through wires hole that is made up of the groove sealing, need not to bore a hole, also need not between collector ring and flabellum, to increase the fixed structure of lead-in wire, therefore easy to assembly.Compare with existing drilling technology, the through wires hole of the utility model is low to required precision, and need not increases extra punching step, easy-formation more in the impact forging moulding, and that can avoid that the punching distortion causes scraps, and therefore can simplify the pawl utmost point and process with flabellum.
Description of drawings
Fig. 1 is the structural representation that the utility model is provided with the reeded pawl utmost point;
Fig. 2 is the cooperation sketch map that the utility model is provided with the reeded pawl utmost point and flabellum.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Like Fig. 1, shown in Figure 2; The automobile generator rotor of the utility model; Comprise installation shaft, the pawl utmost point 1, collector ring, be fixed on the flabellum 2 on the collector ring one end pawl utmost point 1, inter-claw space 11 bottoms of the said collector ring one end pawl utmost point 1 are arc transition, and the adjacent surface of the collector ring one end pawl utmost point 1 and flabellum 2 is provided with two grooves 3; Constitute through hole type through wires hole by flabellum 2 closed pockets 3, aperture and installation shaft that the aperture of through wires hole one end is positioned at inter-claw space 11 bottoms, the other end are adjacent.
During assembling; At first lead-in wire is walked around the inter-claw space 11 of the pawl utmost point 1 and snap in the groove 3; Then flabellum 2 is installed on the pawl utmost point 1; Thereby lead-in wire is fixed in the through wires hole that is made up of groove 3 sealings, need not to bore a hole, also need not between collector ring and flabellum 2, to increase the fixed structure of lead-in wire, therefore easy to assembly.Compare with existing drilling technology, the through wires hole of the utility model is low to required precision, and need not increases extra punching step, easy-formation more in the impact forging moulding, and that can avoid that the punching distortion causes scraps, and therefore can simplify the pawl utmost point and process with flabellum.
Above-mentioned groove 3 can be circular arc, curved, rectilinear etc. along the pawl utmost point 1 axis hole tangential.In instance as shown in the figure, said groove 3 is the straight-line groove along the pawl utmost point 1 radial arrangement.The position of two grooves 3 is provided with by concrete lead-in wire position, and in instance as shown in the figure, two grooves 3 are positioned on the same diameter.
The aperture that above-mentioned through wires hole and installation shaft are adjacent when installation shaft is provided with along wire casing that the installation shaft axis extends, can be arranged on the axis hole inner peripheral surface of the pawl utmost point 1.In instance as shown in the figure, the axis hole periphery of flabellum 2 is provided with and groove 3 corresponding opening 21, and the groove 3 that is exposed by opening 21 places constitutes the through wires hole aperture adjacent with installation shaft; In addition, also can make groove 3 expose through the axis hole that enlarges flabellum 2 and constitute the aperture.But no matter be the axis hole aperture that increases opening 21 or enlarge flabellum 2, all only need when stamping-out flabellum 2 axis holes, to change the shape of drift, and need not to increase the step of stamping-out.
