Abstract
The utility model proposes a kind of stator sector pieces, including：Radially inner side is evenly arranged with the fanning strip ontology of multiple notches, and the radial outside of the fanning strip ontology is provided at least one link slot, for being connect with out frame；The both sides of any one link slot are respectively arranged at least two radiating grooves；It is provided with connecting hole on fanning strip ontology between each link slot and the radiating groove of one side.The stator sector piece of the utility model carries heat sinking function, solves the heat dissipation problem of this stator sector piece, while improving agility and stability that this stator sector piece is connect with out frame.
Description
Technical field
The utility model is related to electrical generator fields, particularly relate to a kind of stator sector piece.
Background technology
Stator core is the important composition component of generator, and stator core is the techniques such as to laminate by stator sector piece to be processed into
Type.The radially inner side of stator sector piece is provided with notch, is used for coiling stator winding；The radial outside of stator sector piece is smooth
Curved surface, for being welded with engine base.The structure of existing this stator sector piece leads to the stator core of high-power generator
External cooling area is insufficient, is easy fever.
Utility model content
The utility model proposes a kind of stator sector piece, solves the problems, such as stator sector piece heat dissipation in the prior art.
What the technical solution of the utility model was realized in：
A kind of stator sector piece, including：Radially inner side is evenly arranged with the fanning strip ontology of multiple notches, the fanning strip
The radial outside of ontology is provided at least one link slot, for being connect with out frame；Distinguish the both sides of any one link slot
It is provided at least two radiating grooves；It is provided with connection on fanning strip ontology between each link slot and the radiating groove of one side
Hole.
Preferably, the radial outside setting of the fanning strip ontology has between two link slots there are two link slot
Predetermined angle；
Angle between two adjacent link slots of two adjacent fanning strip ontologies of head and the tail of arbitrary neighborhood is equal to pre-
If angle.
Preferably, there are three radiating grooves for setting between two link slots.
Preferably, between the quantity of the radiating groove at the head and the tail both ends of each fanning strip ontology and equal to two link slots
The quantity of radiating groove.
Preferably, each link slot is parallelogram, after two or more fanning strip ontology superpositions, the company after superposition
Access slot is the isosceles trapezoid of notch narrow slot bottom width.
The beneficial effects of the utility model are：The stator sector piece of the utility model utilizes the heat dissipation on fanning strip ontology
Slot radiates, and carries heat sinking function, need not separately weld radiating piece in fanning strip ontology, solves stator sector piece heat dissipation and asks
Topic.In addition, be provided with link slot on stator sector piece, for connect with out frame, link slot both can by connector and
Out frame connects, while also functioning to the effect of positioning, is further able to increase the stability and convenience of connection.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of the stator sector piece of the utility model.
In figure：
1, fanning strip ontology；2, link slot；3, radiating groove；4, connecting hole.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment：A kind of stator sector piece as shown in Figure 1, including：Radially inner side is evenly arranged with the fan of multiple notches
The radial outside of shape piece ontology 1, fanning strip ontology 1 is provided at least one link slot 2, for being connect with out frame；It is any
The both sides of a link slot are respectively arranged at least two radiating grooves 3, for radiating；The heat dissipation of each link slot 2 and one side
It is provided with connecting hole 4 on fanning strip ontology between slot 3, convenient for laminating the progress of process.
The radial outside setting of fanning strip ontology 1 has predetermined angle there are two link slot between two link slots；Arbitrarily
Angle between two adjacent link slots of two adjacent fanning strip ontologies of adjacent head and the tail is equal to predetermined angle, so that fixed
Sub- fanning strip is laminated.
Radiating rate in order to better improve, there are three radiating grooves for setting between two link slots.In order to keep head and the tail adjacent
Fanning strip ontology be superimposed faster, the quantity of the radiating groove at the head and the tail both ends of each fanning strip ontology and be equal to two link slots
Between radiating groove quantity.
In order to improve the stability that fanning strip ontology is connected with out frame, each link slot 2 is parallelogram, two
Or after multiple fanning strip ontology superpositions, the link slot after superposition is the isosceles trapezoid of notch narrow slot bottom width.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
