Description
Technical field
The invention belongs to electric machine structure field, is more particularly to a kind of split-type iron core.
Background technology
With the raising of power of motor, the volume of motor also gradually increases, and transport, lifting to motor etc. bring many tired
Difficulty, effectively to solve the problem, the motor of split-type structure turns into a kind of developing direction of heavy-duty motor.
The split-type iron core valve body of motor how to fix and iron core valve body between how to be connected, and to ensure positional precision
With structural strength, turn into split-type structure urgent problem to be solved.
Existing directly bolt type fixes that quantity to be present more, cumbersome, dismantles the problems such as time-consuming, and directly welds then
The maintenance of gas brings difficult, it is necessary to then bring damage with the mode of cutting for insulation when going module to take apart after giving
Risk.
The content of the invention
It is an object of the invention to provide a kind of fixation that can not only realize split-type iron core but also realize iron core valve body and iron core valve
The fixed structure of fixed split-type iron core between body.
According to an aspect of the invention, there is provided a kind of split-type iron core, including multiple iron core valve bodies and for connecting
The retainingf key of multiple iron core valve bodies, the iron core valve body are circular arc type, and the both ends of the split-type iron core are flange face, institute
The both sides for stating iron core valve body are interface, and the interface of the iron core valve body is provided with multiple grooves, and multiple grooves are located at
On straight line, multiple iron core valve bodies are connected into the iron of circular ring type by the way that the retainingf key is fastened in the groove
Core.Split-type reliable fixation unshakable in one's determination is thus achieved, and intensity is high, and operation is simple and reliable, and be particularly suitable for use in split-type iron
The shorter situation of core valve body axial length, dismantle in addition conveniently, can be provided for later stage split-type iron core maintenance of motor feasible
Scheme, the also assembling for large-scale split-type motor provides structural reference.
In some embodiments, multiple through holes are offered on the flange face.It is easy to the later stage that iron core is fixed into dead axle
On.
In some embodiments, the groove and the retainingf key are interference fit.Can be by retainingf key tively firm
It is fastened in groove, prevents to loosen, ensures the integrally-built stabilization of iron core.
In some embodiments, the retainingf key is connected with the inside of the groove for spot welding.Retainingf key can be prevented
Play.
In some embodiments, the retainingf key is fixedly connected with the groove by screw.Retainingf key can be prevented
Play.
In some embodiments, the groove is identical with the shape of the retainingf key.Thus by retainingf key and groove jail
It is solidly connected.
In some embodiments, the retainingf key is rectangle or trapezoidal or triangle or cylinder.Thus by retainingf key
Firmly connected with groove.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the iron core valve body of split-type iron core of an embodiment of the present invention；
Fig. 2 is the structural representation after the connection in two Fig. 1；
Fig. 3 is a kind of structural representation of the retainingf key of split-type iron core of an embodiment of the present invention.
Embodiment
Fig. 1 to Fig. 3 schematically shows the resolution formula iron core of one embodiment of the present invention.Such as Fig. 1 to Fig. 3 institutes
Show, split-type iron core includes multiple iron core valve bodies 1 and the retainingf key 2 for connecting multiple iron core valve bodies 1.
Iron core valve body 1 is circular arc type, and the iron core valve body 1 of circular arc type can form iron core.The both ends of iron core valve body 1 are flange
Face 11.Multiple through holes 111 are offered on flange face 11, are easy to the later stage that iron core is fixed on dead axle by through hole 111.Iron core valve
The two sides of body 1 are interface 12, and the interface 12 of iron core valve body 1 is provided with a groove 121.Groove 121 is rectangular-shape.
The both ends of groove 121 are connected with the both ends of iron core valve body 1.By the way that a retainingf key 2 to be fastened on to two adjacent iron respectively
Multiple iron core valve bodies 1 are connected into the iron core of circular ring type in the groove 121 of core valve body 1.Thus achieve split-type it is unshakable in one's determination can
By fixation, and intensity is high, and operation is simple and reliable, and be particularly suitable for use in the shorter situation of split-type iron core valve body axial length,
Dismantle in addition conveniently, feasible scheme can be provided for later stage split-type iron core maintenance of motor, be also large-scale split-type motor
Assembling provides structural reference.Groove is identical with the shape of retainingf key 2.2 keys can will be fixed tively firm to be fastened in groove,
Prevent to rotate or slide, ensure the integrally-built stabilization of iron core.In other embodiments, groove and retainingf key 2 can be with
For trapezoidal, triangle and cylinder.Groove is interference fit with retainingf key 2, retainingf key 2 is tively firm fastened on groove
In, prevent to loosen, ensure the integrally-built stabilization of iron core.In other embodiments, in order to prevent the play of retainingf key 2,
Retainingf key 2 is connected with the inside of groove for spot welding；Or retainingf key 2 is fixedly connected with groove by screw, the one end of bolt 3
Penetrated from iron core valve body 1 in retainingf key 2.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, do not taking off
On the premise of conceiving from the invention, various modifications and improvements can be made, these belong to protection scope of the present invention.
