Abstract
The utility model relates to a brushless claw-pole vehicle generator rotor. The magnetic yoke and the shaft extension of the rotor shaft are respectively made of materials of different properties and then welded with friction into the shaft body; the weld does not have an air gap, which fully guarantees the technical performance of the rotor shaft. The utility model has the advantages of scientific and rational structure and favorable cost performance ratio.
Description
Affiliated technical field
The utility model belongs to electric machinery, relates to a kind of brush-free claw-pole automobile generator rotor structure specifically.
Background technology
The brush-free claw-pole automobile current generator is the automobile common apparatus.The automobile generator rotor axle becomes step-like, and it normally processes with a 45# garden steel, axis body middle part diameter great thing yoke, and two, left and right sides diameter more carefully is the shaft extension part.The armature spindle of the direct machine-shaping of a kind of material of this use, though processing technology is comparatively convenient, the technical performance that it can only satisfy the shaft extension part can not satisfy the yoke magnetic property, influences generator output.Secondly, armature spindle be enclosed within fore paw extremely in, between axis body and the fore paw utmost point, adopt electric welding, difficulty of processing is big, exists air gap to can hardly be avoided.The magnetic resistance that is brought by air gap then also can influence the output of generator.
Summary of the invention
The utility model purpose is that a kind of brush-free claw-pole automobile generator rotor is provided in order to overcome in the prior art not enough.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of brush-free claw-pole automobile generator rotor, its formation comprises the fore paw utmost point, the rear solid end utmost point, armature spindle, it is characterized in that armature spindle comprises yoke and shaft extension composition, yoke and shaft extension are made by the material of two or more different performances respectively, between the above-mentioned fore paw utmost point and yoke between contact-making surface, yoke and shaft extension contact-making surface all adopt friction welding adult.
Yoke is to be made by the good low-carbon steel material of magnetic property in the technical scheme.
Shaft extension is made by the good high-carbon steel material of hardness performance in the technical scheme.
The beneficial effects of the utility model are, because the main shaft of rotor, its yoke and shaft extension are made by the mild steel and the high-carbon steel of different performance respectively, are connected into axis body through friction welding (FW) again, and weld does not have air gap, and is scientific and reasonable for structure; Secondly, contact-making surface all adopts friction welding adult between contact-making surface between manufacture craft upper magnet yoke and shaft extension and the fore paw utmost point and yoke, and weld can not produce air gap, thereby has guaranteed the armature spindle technical performance and the preferable ratio of performance to price.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structure cutaway view.
Embodiment
Shown in accompanying drawing, the rotor of brush-free claw-pole automobile current generator described in the utility model, by the fore paw utmost point 1, the rear solid end utmost point 2, armature spindle 3 is formed, and armature spindle 3 is made up of yoke 31 and shaft extension 32,33, and yoke 31 adopts mild steel to make, shaft extension 32,33 adopts No. 45 high-carbon steel to make, contact-making surface 5,6 employing friction welding adults between contact-making surface 4, yoke and shaft extension between the above-mentioned fore paw utmost point and yoke.
Claims (3)
1, a kind of brush-free claw-pole automobile generator rotor, its formation comprises the fore paw utmost point, the rear solid end utmost point, armature spindle, it is characterized in that armature spindle is made up of yoke and shaft extension, yoke and shaft extension are made by the material of two or more different performances respectively, between the above-mentioned fore paw utmost point and yoke between contact-making surface, yoke and shaft extension contact-making surface all adopt friction welding adult.
2, automobile generator rotor according to claim 1 is characterized in that yoke is to be made by the good low-carbon steel material of magnetic property.
