Abstract
The utility model discloses a rotor for an alternating-current generator. The rotor comprises a front claw pole, a back claw pole and a rotating shaft, wherein the front claw pole comprises a boss; the inner diameter of the boss is greater than the inner diameter of the front claw pole; and the front claw pole is fixed with the rotating shaft through the boss. In the rotor, the axial size of the rotating shaft can be adjusted, so that the assembly process flow is reduced.
Description
Technical field
The utility model relates to a kind of technical field of generators, relates in particular to a kind of rotor that is used for alternating current generator.
Background technology
In automobile, the effect of alternating current generator is that the part mechanical energy with engine becomes electric energy, to all power consumption equipments power supplies except that starter, and in time storage battery is carried out boost charge.Alternating current generator mainly is made up of rotor, stator and front and rear cover etc.Rotor is the rotating magnetic field part of three-phase synchronous alternator.
As shown in fig. 1, Fig. 1 is the part of employed rotor in the prior art, and this rotor comprises rotating shaft 1, the fore paw utmost point 2 and the rear solid end utmost point 3, adopts usually in the prior art fore paw utmost point 2, the rear solid end utmost point 3 are fixed with the mode that rotating shaft 1 press-fits respectively.Generally, the fore paw utmost point 2 of this rotor, the rear solid end utmost point 3 are fixing with rotating shaft 1 respectively, and the axial dimension of its rotating shaft 1 is difficult to regulate.And in assembling process, must strictly distinguish the fore paw utmost point 2, the rear solid end utmost point 3, avoid that the two is out of position, so the assemble flow complexity, be unfavorable for the raising of output.
Summary of the invention
The purpose of this utility model is to provide a kind of rotor that is used for alternating current generator, and this rotor can be regulated the axial dimension of rotating shaft, reduces the assembly technology flow process.
For achieving the above object, the disclosed technical scheme of the utility model thes contents are as follows:
A kind of rotor that is used for alternating current generator comprises the fore paw utmost point, the rear solid end utmost point and rotating shaft, and this fore paw comprises a boss on extremely, and described boss internal diameter is greater than described fore paw utmost point internal diameter, and the described fore paw utmost point is fixed by described boss and rotating shaft.
Further, this fore paw utmost point and described boss forging and molding.
Further, the diameter of this rotating shaft is 12mm to 22mm.
Further, this boss internal diameter is 14mm to 24mm.
Further, the thickness of this boss is 2mm to 4mm.
Further, the thickness of this boss is 2.5mm.
Further, the height of this boss is 3mm to 8mm.
Further, the height of this boss is 6.5mm.
Compared with prior art, the rotor that is used for alternating current generator provided by the utility model by setting up a boss at fore paw on extremely, can be regulated the axial dimension of rotating shaft, reduces alternating current generator assembly technology flow process.
Description of drawings
Can be about the advantages and spirit of the present invention by following detailed Description Of The Invention and appended graphic being further understood.
Fig. 1 is the structural representation of employed rotor in the prior art;
Fig. 2 is the profile of the fore paw utmost point of the related rotor of the utility model;
Fig. 3 is the profile of the related rotor of the utility model.
Embodiment
Describe specific embodiments of the invention in detail below in conjunction with accompanying drawing.
As shown in Figure 2, Fig. 2 is the profile of the fore paw utmost point of the related rotor of the utility model.Among Fig. 2, this fore paw utmost point is made up of two parts, comprises the fore paw utmost point 201 and boss 202.This boss 202 and the fore paw utmost point 201 are one-body molded when forging.The internal diameter of boss 202 is greater than the internal diameter of the fore paw utmost point 201.When the fore paw utmost point of the prior art is connected with rotating shaft, directly press-fits to form or increase by a part and be used for auxiliary the installation.The fore paw utmost point and the auxiliary part of installing are compressed into rotating shaft together, and size of should auxiliary thickness that part is installed regulating rotor by the machine work smear metal, so not only increased and pressed the auxiliary operation that part is installed, satisfied the rotor axial dimensional requirement but also will after the rotor assembling, also will carry out machining.The utility model increases by a boss 202 at fore paw when the fore paw utmost point forges on extremely, reserves the axial dimension that needs, and need not carry out smear metal in addition after the rotor assembling and process.
As shown in Figure 3, Fig. 3 is the profile of the related rotor of the utility model.This rotor comprises the fore paw utmost point 201, rotating shaft 101 and the rear solid end utmost point 301.The structure of the fore paw utmost point of the prior art and the rear solid end utmost point is closely similar, and difference is slightly only arranged.In the alternating current generator assembling process, must strictly distinguish the fore paw utmost point, the rear solid end utmost point, avoid that the two is out of position.Therefore need increase at assembly technology and distinguish flow process, also therefore increase installation time.By on the fore paw utmost point 201, increasing by a boss 202, on structure, distinguish, and then can omit differentiation flow process in the alternating current generator assembling process with the rear solid end utmost point 301, reach the purpose that reduces installation time.
The rotor that is used for alternating current generator, the diameter of its rotating shaft 101 can be designed as between the 12mm to 22mm, and the internal diameter of its boss 202 is slightly larger than the diameter of rotating shaft 101, can boss 202 internal diameters be designed between the 14mm to 24mm according to the diameter of rotating shaft 101.It uses durability degree stronger in order to make rotor provided by the utility model, and reliability is better.The thickness of boss 202 can be designed to be preferably 2.5mm between the 2mm to 4mm, and the height of boss 205 can be designed to be preferably 6.5mm between the 3mm to 8mm.
Compared with prior art, the rotor that is used for alternating current generator provided by the utility model by setting up a boss at fore paw on extremely, can be regulated the axial dimension of rotating shaft, reduce alternating current generator assembly technology flow process, and can improve the durability degree and the reliability of rotor.
Described in this specification is preferred embodiment of the present invention, and above embodiment is only in order to illustrate technical scheme of the present invention but not limitation of the present invention.All those skilled in the art all should be within the scope of the present invention under this invention's idea by the available technical scheme of logical analysis, reasoning, or a limited experiment.
