Background technology
At present, aero dynamo rotor is manufactured with slot wedge using steel plate integrated sheet-metal bending, without hole slot in both wings plane, this knot
Structure is when air-flow is by rotor, it is impossible to directly contact rotor windings surface, and the heat that rotor windings are produced is difficult to shed, easily
Rotor is caused to cross heat damage winding insulation, rotor cooling effect is poor.
The content of the invention
The purpose of this utility model is to improve slot wedge structure, product radiating efficiency is improved, so as to ensure that aero dynamo is good
High temperature resistant service behaviour；And reduce the weight of slot wedge, to reduce product weight, reach the purpose for improving aircraft start performance.
The technical solution of the utility model is：
A kind of aero dynamo rotor is with Formula V type groove wedge with holes, it is characterised in that：Along rotor in the both wings plane of slot wedge
Axially it is provided with some convection holes.
Further preferred scheme, a kind of aero dynamo rotor is with Formula V type groove wedge with holes, it is characterised in that：It is described
Convection holes are uniformly distributed on rotor axial.
Further preferred scheme, a kind of aero dynamo rotor is with Formula V type groove wedge with holes, it is characterised in that：It is described
Convection holes are square opening.
Further preferred scheme, a kind of aero dynamo rotor is with Formula V type groove wedge with holes, it is characterised in that：In groove
In each wing plane of wedge, some groups of convection holes are uniformly distributed along rotor axial, every group of convection holes are made up of two convection holes, two
The vertical slot wedge folding line arrangement of individual convection holes.
Beneficial effect
Using the utility model proposes slot wedge, can directly cool down thermal source Exciting Windings for Transverse Differential Protection, increase thermal convection current radiating can
Radiating efficiency is improved, so as to improve the high temperature resistant service behaviour of aero dynamo, it is ensured that aircraft will to the harsh of environment temperature index
Ask.Meanwhile, present invention decreases the weight of slot wedge, airborne products weight can be reduced, so as to improve aircraft start performance.
Additional aspect and advantage of the present utility model will be set forth in part in the description, partly by from following description
In become obvious, or by it is of the present utility model practice recognize.
Brief description of the drawings
Of the present utility model above-mentioned and/or additional aspect and advantage will from description of the accompanying drawings below to embodiment is combined
Become substantially and be readily appreciated that, wherein：
Fig. 1 is three dimensional structure diagram of the present invention；
The rotor three dimensional structure diagram of Fig. 2 assembling present invention.
Wherein, 1 is slot wedge, and 2 be rotor core, and 3 be rotor windings.
Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element or element with same or like function are represented to same or similar label eventually.Below by ginseng
The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model
Limitation.
In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width
Degree ", " thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer ",
The orientation or position relationship of the instructions such as " clockwise ", " counterclockwise " be based on orientation shown in the drawings or position relationship, be only for
It is easy to description the utility model and simplifies describe, rather than to indicate or imply that signified device or element must have specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
The purpose of this utility model is to improve slot wedge structure, product radiating efficiency is improved, so as to ensure that aero dynamo is good
High temperature resistant service behaviour；And reduce the weight of slot wedge, to reduce product weight, reach the purpose for improving aircraft start performance.
As shown in figure 1, the aero dynamo rotor is with Formula V type groove wedge with holes, opened in the both wings plane of slot wedge along rotor axial
There are some square convection holes, convection holes are uniformly distributed on rotor axial；It is equal along rotor axial in each wing plane of slot wedge
Some groups of convection holes of even distribution, every group of convection holes are made up of two convection holes, the vertical slot wedge folding line arrangement of two convection holes.
Using the rotor of the present invention with Formula V type groove wedge with holes, when aero dynamo cooling air-flow passes through rotor, can directly it cool down
Thermal source Exciting Windings for Transverse Differential Protection, adds thermal convection current radiating, and the Exciting Windings for Transverse Differential Protection type of cooling couples cold for heat exchange pattern with thermal convection current mode
But, radiating efficiency is improved, so as to improve the high temperature resistant service behaviour of aero dynamo, it is ensured that aircraft is tight to environment temperature index
It is cruel to require.Meanwhile, this structure slot wedge relatively reduces the weight of traditional slot wedge, reduces airborne products weight, can improve aircraft
Start performance.
Rotor is with Formula V type groove wedge three-dimensional structure with holes as shown in figure 1, assembling rotor three-dimensional structure such as Fig. 2 institutes of this slot wedge
Show, the hole of winding heat from V-groove wedge sheds, taken away by the air-flow circulated along rotor axial direction.
Although embodiment of the present utility model has been shown and described above, it is to be understood that above-described embodiment is
Exemplary, it is impossible to it is interpreted as to limitation of the present utility model, one of ordinary skill in the art is not departing from the utility model
Principle and objective in the case of above-described embodiment can be changed in the range of the utility model, change, replace and
Modification.
