Description
Technical field
The technical field of middling speed magneto alternator rotor magnetic pole installation is the utility model is related to, is referred in particular in one kind
Fast magneto alternator rotor magnetic pole mounting structure.
Background technology
Middling speed magneto alternator used in wind-driven generator unit at present, in order to ensure the reliability of field structure
Embedded field structure is used mostly, while is turned for the ease of the processing of permanent magnet, the structure of usual magnetic pole segmentation, i.e. generator
By 8-10, individually magnetic poles are spliced for each pole of son, so for how by the magnetic pole splicing of multiple segmentations again with rotor
Support, which reliably connects, becomes a technical barrier.
(see Fig. 1) in conventional design, first two square openings of punching press in each rotor magnetic pole punching, recycle two
Square screw rod is penetrated in the square opening in punching, by it is each extremely on single rotor magnetic pole be concatenated into together, both ends pass through
The pole end-plate of two pieces of stainless steels is linked together using nut, while the radial direction of every square screw rod processes four spiral shells
Pit, punching press one bolt hole is reserved in the radial direction in the rotor magnetic pole punching of screwed hole correspondence position, rotor field spider it is outer
Four through holes are processed in radial direction corresponding to surface, then rotor magnetic pole is installed on rotor field spider by bolt.
Following technological difficulties be present according to conventional design：
1st, rotor magnetic pole is connected by bolt with rotor field spider, and rotor is subjected to centrifuge in rotor magnetic pole rotary course
The effect of the complicated power such as power, unilateral magnetic force, it is higher for the process control requirements of bolt installation, and bolt quantity is more
(each pole 8, every pole of motor 24) expends man-hour.
2nd, four rotor magnetic pole punchings have been needed on each rotor magnetic pole in two through holes of radial direction punching press, the punching press of punching
Technique becomes complicated, and is not easy to the management and control of material.
3rd, substantial amounts of (each pole 8, every pole of motor 24, the totally 192) through hole of processing is needed on rotor field spider, while need to be adopted
With the lead to the hole site of hook milling cutter rotor field spider intrados put down ream, the processing technology of rotor field spider becomes sufficiently complex.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art and shortcoming, it is proposed that a kind of safe and reliable, simple
Middling speed magneto alternator rotor magnetic pole mounting structure practical, simple and efficient to handle so that the processing of part becomes more
Simplicity, assembly technology are more convenient.
To achieve the above object, technical scheme provided by the utility model is：A kind of middling speed magneto alternator turns
Sub- magnetic pole mounting structure, the rotor magnetic pole punching of rotor magnetic pole is designed to dovetail configuration, and in middling speed magneto alternator
Rotor field spider on the dovetail groove of corresponding construction is processed using profile milling cutter, the rotor magnetic pole punching is stacked to be placed on rotor
In dovetail groove on support, and there is gap in an one side side corresponding with dovetail groove, be adapted for placing size
Wedge, place wedge toward the gap and rotor magnetic pole punching is connected with rotor field spider for interference, will after placement wedge
The magnet steel pressing plate of two pieces of stainless steels is installed at the both ends of rotor magnetic pole, ensures rotor in rotary course, rotor magnetic pole will not
Get loose.
The utility model compared with prior art, has the following advantages that and beneficial effect：
1st, rotor magnetic pole punching uses dovetail configuration, and rotor field spider uses oat tail groove structure, connected by wedge interference
Mode, the traditional structure that compares eliminates substantial amounts of connecting bolt, while having saved cost of parts, eliminates installation bolt
Man-hour used.
2nd, installation bolt is more strict for assembling process technology controlling and process, and reliability is low, and is being set using oat tail groove structure
Rotor magnetic pole is reduced on meter and occurs the risk released in rotor rotation process, structure is reliable.
3rd, all rotor magnetic pole size shapes are all general, without distinguishing, it is only necessary to distinguish N, S pole, greatly save
The warehouse cost of material.
4th, the dovetail groove on rotor field spider is processed and formed at one time using profile milling cutter, and processing technology is easy.
Brief description of the drawings
Fig. 1 is middling speed magneto alternator rotor magnetic pole mounting structure schematic diagram of the present utility model.
Fig. 2 is middling speed magneto alternator rotor magnetic pole mounting structure sectional view of the present utility model.
Embodiment
With reference to specific embodiment, the utility model is described in further detail.
Referring to shown in Fig. 1 and Fig. 2, the middling speed magneto alternator rotor magnetic pole mounting structure described in the present embodiment, have
Body is that the rotor magnetic pole punching 1 of rotor magnetic pole is designed into dovetail configuration, and in the rotor field spider 2 of middling speed magneto alternator
On the dovetail groove 3 of corresponding construction is processed using profile milling cutter, the rotor magnetic pole punching 1 is stacked to be placed on rotor field spider
In dovetail groove 3, for the reliability of generator operation, an one side side corresponding with dovetail groove 3 reserves 5mm gap,
The wedge 4 being adapted for placing size, place wedge 4 toward the gap and make it that rotor magnetic pole punching 1 is with rotor field spider 2
Interference is connected, and the both ends of rotor magnetic pole are installed to the magnet steel pressing plate 5 of two pieces of stainless steels after placement wedge 4, ensure rotor
In rotary course, rotor magnetic pole will not be got loose.
Examples of implementation described above are only the preferred embodiment of the utility model, are not limited with this of the present utility model
Practical range, therefore the change that all shape, principles according to the utility model are made, all should cover in the scope of protection of the utility model
It is interior.
