Description
Technical field
It the utility model is related to machine field, and in particular to a kind of stator pressing ring and traction electric machine.
Background technology
Stator pressing ring is a kind of Electric machine structure part, to compress stator lasmination, as shown in figure 1, it is applied more to be a kind of
Extensive stator pressing ring structure.
From Fig. 1, it can be seen that because stator pressing ring function is more single, its structure is also relatively simple.
Therefore, although existing scheme is using relatively broad, simple in construction, function is single, and the motor of specific function is come
Say not optimal selection.
Utility model content
The purpose of this utility model is to provide a kind of stator pressing ring suitable for traction electric machine.
In order to solve the above-mentioned technical problem, the utility model provides a kind of stator pressing ring, including：In determining for octagonal shape
Sub- trim ring body, positioned at one side of stator pressing ring body be provided with two protrusion upper arms, two protrusion upper arms be suitable to on engine truck
Resilient support be connected.
Further, some air vents are placed with along the inner ring circumferencial direction of stator pressing ring body, and respectively with stator punching
On air vent composition stator ventilating duct.
Further, by each air vent be divided into four groups and respectively stator pressing ring body inner ring in diagonal it is symmetrical.
Further, each group air vent includes 7 air vents.
Further, a wire hole is additionally provided with the stator pressing ring body, the three-phase of stator winding draws copper bar and is suitable to lead to
The wire hole is crossed to be immediately directed against in terminal box from motor internal.
Another aspect, the utility model additionally provide a kind of traction electric machine.
The traction electric machine includes said stator trim ring.
The beneficial effects of the utility model are, this stator pressing ring is provided with two protrusion upper arms, can with engine truck
Resilient support is connected, and to hang motor, the repetition for avoiding suspension device of motor is set, and simplifies electric machine structure；Therefore, originally
Stator pressing ring it is particularly suitable power is big, on locomotive traction motor of small volume.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is a kind of widely used stator pressing ring structure；
Fig. 2 is the structural representation of stator pressing ring of the present utility model；
Fig. 3 is the profile of A-A positions in Fig. 2.
In figure, stator pressing ring body 1, inner ring 100, two protrude upper arm 101, resilient support 102, air vent 103, wire hole
104。
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
Embodiment 1
Fig. 2 is the structural representation of stator pressing ring of the present utility model；
As shown in Fig. 2 a kind of stator pressing ring of the present utility model, including：In the stator pressing ring body 1 of octagonal shape, position
Two protrusion upper arms 101 are provided with one side of stator pressing ring body 1, two protrusion upper arms 101 are suitable to and the elasticity on engine truck
Support 102 is connected.
This stator pressing ring is provided with two protrusion upper arms 101, can be connected with the resilient support 102 on engine truck, to
Motor is hung, the repetition for avoiding suspension device of motor is set, and simplifies electric machine structure；Therefore, this stator pressing ring is particularly suitable
Power is big, on locomotive traction motor of small volume.
In the present embodiment, some air vents 103 are placed with along the circumferencial direction of inner ring 100 of stator pressing ring body 1, and divided
Stator ventilating duct, the motor that the design needs to divulge information especially suitable for stator are not formed with the air vent 103 on stator punching.
As a kind of preferred embodiment of air vent 103, each air vent 103 is divided for four groups and respectively in stator pressure
It is symmetrical in diagonal to enclose the inner ring 100 of body 1, each air vent 103 is improved ventilation effect around setting.
Optionally, each group air vent 103 includes 7 air vents 103, and ventilation effect is improved using multiple air vents side by side 103
Fruit.
Fig. 3 is the profile of A-A positions in Fig. 2.
As shown in figure 3, being additionally provided with a wire hole 104 on the stator pressing ring body 1, the three-phase of stator winding draws copper bar
Suitable for being immediately directed against by the wire hole 104 from motor internal in terminal box, the design effectively shortens winding and terminal box
Connection distance.
Embodiment 2
On the basis of embodiment 1, the present embodiment 1 provides a kind of traction electric machine, including：Stator as described in Example 1
Trim ring.
This stator pressing ring is provided with two protrusion upper arms 101, simplifies electric machine structure；Wire hole 104 is additionally provided with, is effectively shortened
The connection distance of winding and terminal box, and the symmetrical motor ventilation hole 103 of diagonal is set, needed suitable for stator
The motor of ventilation, and then meet a variety of motor needs.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right
Property scope.
