Abstract
The invention relates to an assembly method of an electric generation rotor, which is composed of a shaft, having a set of grooves at both ends and a knurling portion and a rotor having a boss. The knurling portion is formed as the part where many projected portions are formed. The boss 6 is formed as a part projected to the enter axis of the rotor and has a height capable of sizing. The shaft and rotor can be coupled rigidly, by having the shaft inserted into the axial hole of rotor and then burying a part of the boss to the knurling portion and groove through the sizing.
Description
Technical field
The present invention relates to the assembly method of generator amature, on being arranged at vehicle etc. and provide in the generator of electric power, the axle of setting combines easily with being pressed into aforementioned centre of rotor part to make the rotor that is arranged on this generator, it is crooked and produce distortion in process of press in to prevent to be arranged at aforementioned epitrochanterian axle, can farthest reduce the off-centre of aforementioned rotor, farthest reduce the imbalance revolution of rotor when revolution, improve the performance of generator.
Background technology
The rotor that is provided with in the electric generater of vehicle of prior art, axial compression is gone into that rotor center portion is provided with by system, as shown in Figures 1 and 2, the side of aforementioned axis 1 from rotor 4 is pressed into forcibly, thereby aforementioned axis 1 begins just to be subjected to powerful resistance from the axis hole of just going into rotor, make aforementioned axis produce initial distortion thus, when axle 1 one side insert the rotor one side by central portion, until an end of aforementioned axis 1 expose in the process, also produce the distortion of aforementioned axis 1 continuously, aforementioned axis 1 can form concavo-convex state in the occasion of fierceness distortion.
On the other hand, if when aforementioned axis 1 is out of shape, then to carry out rectification work as top to it.But, expose the linearity that links up to axle 1 the two ends and the centre of rotor line of aforementioned rotor exterior in mensuration, and the occasion of aforementioned axis 1 bending, will correct this sweep, and, in the occasion of aforementioned rotor, will cut the eccentric part of aforementioned rotor and assign to correct with respect to axle 1 off-centre.
Therefore, as mentioned above, with rotor with the axle combine after, the method of correcting the prior art of this distortion is to reserve the cut amount of rotor in advance, must do its thickness thicker, owing to when correcting axle, also can only correct the two ends of axle merely, can't carry out real rectification work so grade for the pars intermedia of axle, thus, the manufacturing of aforementioned rotor and axle and combine operation and become insoluble problem.Be the air gap of maintenance with the precision of stator, rotor is carried out accurate external diameter processing, so the cut quantitative change is big, owing to be that benchmark is processed with eccentric or crooked, therefore such shortcoming is arranged, promptly after to aforementioned axis processing, its external diameter processing is to be partial to eccentric processing on one side, thus, naturally make the eccentric quantitative change of aforementioned axis big, greatly reduced the durability of generator, production efficiency is reduced, made the decreased performance of generator etc.
Summary of the invention
The present invention develops in view of the variety of issue that exists in the above-mentioned prior art, and its purpose is to provide a kind of assembly method of generator amature.
A kind of assembly method of generator amature, it is characterized in that: the assembling of described rotor comprises following operation: in the inboard at the position that combines with central rotor of axle or the outside be formed obliquely separately knurled portion, and the mountain shaped protrusions of aforementioned knurled portion is made little, and form a plurality of; With part that described axle combines on, the two ends in the central shaft part of the utmost point portion of aforementioned rotor outwards form wheel hub respectively highlightedly, and aforementioned wheel hub are formed the height that can carry out pressure-sizing processing; After the axle that will be shaped as described above inserts in the axis hole of utmost point portion of rotor, the wheel hub that forms in aforementioned utmost point portion is carried out pressure-sizing processing, make the part of wheel hub be filled in the knurled portion that forms on the aforementioned axis by aforementioned pressure-sizing/ca(u)lk processing, and, aforementioned axis is combined securely with rotor by a this part of being filled up by wheel hub.
This method can make the rotor that is arranged on the generator, and the axle of setting combines easily with being pressed into aforementioned centre of rotor part, can prevent to be arranged on aforementioned epitrochanterian axle and in process of press in, produce distortion because of bending, can farthest reduce the off-centre of aforementioned rotor, thereby farthest reduce the imbalance of rotor when revolution, omit above-mentioned rectification work owing to avoiding the aforementioned rotor and the distortion of axle, can farthest reduce the external diameter processing capacity of rotor, need not carry out the eccentric processing and the one-sided processing of axle, thereby can improve the durability of the high speed rotary of generator, improve its performance.
Below, the present invention is described in detail according to following drawings and Examples.
Description of drawings
Fig. 1 and Fig. 2 are the axle of prior art and the cutaway view of rotor bonding state.
Fig. 3 is the cutaway view of the operation of the embodiment of the invention.
Fig. 4 is the cutaway view of the confined state of the embodiment of the invention.
Embodiment
First operation (forming process of axle)
The position that combines with central rotor 4 at axle 1 forms a pair of trench portions 2, and the side or the outside are formed obliquely knurled portion 3 separately within it; In addition, also can not form aforementioned groove, but be formed obliquely knurled portion in the inboard outside.The mountain shaped protrusions of aforementioned knurled portion 3 is made little, and formed a plurality of.
Second operation (forming process of rotor)
Two ends in the central shaft part of the utmost point portion (ボ-Le) 5 of aforementioned rotor 4 form outstanding laterally wheel hub 6 respectively, but aforementioned wheel hub 6 are formed the height of pressure-sizing processing.
The 3rd operation assembly process of rotor (axle with)
As the assembly process of the axle 1 that is shaped as described above with rotor 4, after in the axis hole of the utmost point portion 5 that aforementioned axis 1 is inserted rotor 4, the wheel hub 6 that forms in aforementioned utmost point portion 5 is carried out pressure-sizing processing, by this pressure-sizing processing, the part of wheel hub 6 is filled in respectively on the aforementioned axis 1, form knurled portion 3 and trench portions 2, thereby and fill up by a this part and to make aforementioned axis 1 firm with combining of rotor 4 by wheel hub 6.
The axle 1 and the rotor 4 that assemble up by above-mentioned operation, even do not force to be pressed into processing, also can make them easily and combination securely, can reduce the distortion that is combined in the axle 1 in the aforementioned rotor 4 widely, do not need axle is carried out rectification work with other method yet, needn't as prior art, reserve the cut amount and aforementioned rotor is corrected.
As mentioned above, in the present invention, owing on above-mentioned axle 1, form groove 2 and knurled portion 3, in the utmost point portion 5 of aforementioned rotor 4, form wheel hub 6, when aforementioned axis 1 is combined with rotor 4, wheel hub 6 to aforementioned utmost point portion 5 carries out pressure-sizing processing, just axle 1 can be assembled securely, can not produce the sort of axle of prior art and the distortion of rotor, thus, do not need the foregoing axle that carries out because of distortion and the rectification work of rotor, thereby can make the easy to manufacture of aforementioned axis and rotor, also can be with the reduced thickness of rotor, therefore, can make the external process amount of axle minimum, owing to can significantly reduce the off-centre of aforementioned rotor,, improve the durability of the generator of high speed rotary significantly so can farthest reduce the non-equilibrium state of revolving body, make the stable action of revolving body, and improve the performance of generator significantly.
