Description
Technical field
The utility model belongs to motor stator core technical field, is more particularly to a kind of motor stator core fixed knot
Structure.
Background technology
The cooperation of electric machine iron core and pedestal at present uses interference fits mostly, it is necessary to support and the processing essence of iron core mating surface
Degree is very high, also to realize assembling using hot jacket by the way of in addition, in order to prevent between iron core and support it is mobile need to be using pin
Mode, live drilling is needed again, assembling technology procedure is more complicated, cumbersome, the work of summer oven drying temperature high workload personnel
Environment is more severe.
The temperature rise of motor is inevitable, effectively to reduce the temperature rise of motor, improves motor insulating reliability, motor has at present
A variety of types of cooling, it is molded for the hot jacket of electric machine iron core and support, the heat of iron core can only be conducted by support to be dissipated
Go out.If using new assembling scheme, the selection of the type of cooling of motor is added, effectively reduces the temperature rise of motor, is improved
The operational reliability of motor.
Generally use iron core is interference fitted with support or the mode of interference fits, is covered by the process of hot jacket
Dress, then further strengthened by pin, prevent the movement between iron core and support.But the processing capacity of this assembly method mating surface
Greatly, requirement on machining accuracy is higher, and radiating mode selection is limited, and radiating effect is limited to.
Utility model content
It is high and can the higher motor stator core of radiating efficiency that the purpose of this utility model is to provide a kind of machining accuracy
Fixed structure.
According to one side of the present utility model, there is provided a kind of fixed structure of motor stator core, including iron core, mistake
Part, end cap and support are crossed, the transition piece is fixedly connected with the iron core, and the transition piece is connected by bolt and the end cap
Connect, the end cap is vertically arranged with the transition piece, and the end cap is connected with the end of the support and covers the support
End face, the iron core be arranged in parallel with the support, are provided between the iron core and the support and are used to accommodate cooling-part
Space.
The utility model is integrally welded using axially assembling, first iron core with transition piece, reduces iron core Excircle machining amount,
Machining accuracy is higher and cost is relatively low；Iron core with transition piece and end cap are assembled, fixes, now only needs processed through bolt
The locating slot crossed on the cylindrical and end casing of part, processing capacity greatly reduce；Said structure can make between iron core and support
The cooler of spatial arrangement cooling iron core, such as cold water, air-cooled can be provided.
In some embodiments, the iron core is welded to connect with the transition piece.Thus improve end turn space and
Iron core intensity.
In some embodiments, the inner side of the end cap is provided with step groove, the connection ring of the inner side of the support and institute
Step groove is stated to be bonded and be bolted to connection.The end cap of ribbon core assembles with support again, and support passes through step groove with end cap
Coordinate, it is ensured that assembling positioning.
In some embodiments, the end cap is structure as a whole with the support.It will can be held to simplify assembling process
Lid is replaced with support with casting, by support and end cap cast solid in casting process；So that what end cap connected with support
It is more firm so that iron core is more firm to be fixed on support.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the fixed structure of motor stator core of the embodiment of the utility model one.
Embodiment
Fig. 1 schematically shows a kind of fixed structure of the motor stator core 3 of embodiment of the present utility model.Such as
Shown in Fig. 1, the motor stator core 3 includes iron core 3, transition piece 4, end cap 2 and support 1.
Transition piece 4 is fixedly connected with iron core 3.Specifically, iron core 3 is welded to connect with transition piece 4, thus improves end turn
Space and the intensity of iron core 3.Transition piece 4 is connected by bolt with end cap 2, and end cap 2 is vertically arranged with transition piece 4.End cap 2 and machine
The end connection of seat 1 and the end face of covering support 1.In this embodiment, the inner side of end cap 2 is provided with step groove, support 1 it is interior
The connection ring of side is bonded and is bolted to connection with step groove.The end cap 2 of ribbon core 3 assembles with support 1 again, support 1 with
End cap 2 is coordinated by step groove, it is ensured that assembling positioning.In other embodiments, end cap 2 is integrated knot with support 1
Structure.End cap 2 and support 1 can be replaced with casting to simplify assembling process, cast support 1 and end cap 2 in casting process
One；So that end cap 2 and support 1 connect it is more firm so that iron core 3 is more firm to be fixed on support 1.Iron core
3 are be arranged in parallel with support 1, and the space for being used for accommodating cooling-part is provided between iron core 3 and support 1.The utility model is integrally adopted
With axial assembling, iron core 3 first welds with transition piece 4, reduces the Excircle machining amount of iron core 3, machining accuracy is higher and cost compared with
It is low；Iron core 3 with transition piece 4 is assembled with end cap 2, fixed through bolt, now only needs to process the cylindrical and end cap of transition piece 4
Locating slot on 2 plates, processing capacity greatly reduce；Said structure can make that space row can be provided between iron core 3 and support 1
Cloth cools down the cooler of iron core 3, such as cold water, air-cooled.
Above-described is only some embodiments of the present utility model.For those of ordinary skill in the art, exist
On the premise of not departing from the utility model creation design, various modifications and improvements can be made, it is new that these belong to this practicality
The protection domain of type.
