To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below by specific embodiment party
Formula is described in further detail to the utility model.
" one embodiment " or " embodiment " referred to herein refers to may be included at least one realization side of the utility model
Special characteristic, structure or characteristic in formula." in one embodiment " that different places occur in this manual not refers both to
Same embodiment, nor the single or selective embodiment mutually exclusive with other embodiment.
MW levels rotor of direct-drive permanent magnet wind driven generator iron core unshakable in one's determination is laminated by punching, and the punching includes punching
Film trap, after a plurality of punchings are stacked layer by layer, the punching groove in each punching connects to form a longer punching groove.In order to
Prevent punching from producing skew in lamination process, and eliminate the sawtooth being likely to occur in punching groove, side set phenomenon, the utility model
Provide a kind of new MW level rotor of direct-drive permanent magnet wind driven generator iron core laminating frocks.
As shown in Figures 1 to 4, MW levels rotor of direct-drive permanent magnet wind driven generator iron core laminating frock provided by the utility model
Including upper prefabricating plate 1, precompression screw 2, lower prefabricating plate 3 and groove lining bar 4.
The upper prefabricating plate 1 and the lower prefabricating plate 3 are cyclic structure, the upper prefabricating plate 1 and the lower prefabricating plate 3
External diameter of the external diameter with the mounting bracket unshakable in one's determination 6 of the generator amature match.It is circumferentially uniform on the upper prefabricating plate 1
A plurality of connecting holes 11 are equipped with, internal thread is provided with the connecting hole 11.Circumferentially formed with level on the lower prefabricating plate 3
Supporting surface 31.
The aperture of the external diameter of the precompression screw 2 and the connecting hole 11 matches, and is set on the outer wall of the precompression screw 2
There is the external screw thread that the screw-internal thread fit with the connecting hole 11 uses.
The width of the groove lining bar 4 is slightly less than the groove width for the punching for forming the generator rotor core.It is specific at some
In embodiment, the width of the groove lining bar 4 is smaller 0.1-0.2mm than the groove width of the punching.
The installation and removal of the groove lining bar 4 for convenience, in certain embodiments, as shown in figure 4, the groove sample
Rod 4 includes the body 41 of rectangle and forms the boss 42 on the body 41, and institute can be easily moved through the boss 42
State groove lining bar 4.
Please continue to refer to shown in Fig. 1, MW levels rotor of direct-drive permanent magnet wind driven generator iron core laminating provided by the utility model
The application method of frock is as follows：
A, punching is stacked layer by layer to the core slots of mounting bracket 6 unshakable in one's determination, starts the structure of generator rotor core 5.
B, after the first predetermined thickness has often been folded in punching, a groove lining bar 4 is respectively mounted in each punching groove, to complete once
The adjustment alignment of punching.
Groove lining bar 4 effectively can prevent punching from occurring local offset during stacking, so as to reduce the unevenness degree of punching.This
Outside, groove lining bar 4 can eliminate the sawtooth occurred in punching groove, the side set imagination.
C, after the second predetermined thickness has often been folded in punching, a precompressed is carried out, to realize the compression layer by layer of each punching.
Specific pre-compaction process is as follows：First, the lower prefabricating plate 3 is hoisted to the upper surface of punching layer, on described
Prefabricating plate 1 is hoisted on the rotor-end capping of generator rotor core；Then, by the corresponding installation of a plurality of precompression screws 2
Screw in the connecting hole 11 and downwards, until the lower end of each precompression screw 2 and the supporting surface 31 are inconsistent, with reality
Now downward precompressed；After precompressed terminates, the precompression screw 2, the upper prefabricating plate 1 and the lower prefabricating plate 3 are removed successively.
Because a plurality of connecting holes 11 are evenly distributed on the upper prefabricating plate 1, therefore in pre-compaction process, iron core
The uniform force of mounting bracket 6, so as to be deformed because of unbalance stress.
D, when punching layer reaches predetermined thickness, end plate is soldered on the upper surface of punching layer, generator rotor core 5
Structure is completed, and each precompression screw 2 is removed out of punching groove.
In certain embodiments, first predetermined thickness is 90-100mm, and second predetermined thickness is 200-
220mm。
In certain embodiments, the duration of each precompressed is 30 minutes, precompression 200N.m-250N.m.
, can not only be complete using MW levels rotor of direct-drive permanent magnet wind driven generator iron core laminating frock provided by the utility model
Laminate shaping into generator rotor core, and efficiently solve generator rotor core occur in lamination process sawtooth,
Phenomena such as side set, and the unevenness degree of punching can be reduced.
Described above fully discloses specific embodiment of the present utility model.It is pointed out that it is familiar with the neck
Any change that the technical staff in domain is done to specific embodiment of the present utility model is all without departing from right of the present utility model
The scope of claim.Correspondingly, the scope of claim of the present utility model is also not limited only to foregoing specific embodiment party
