Abstract

The invention relates to a ventilation slot plate for a direct current motor, which comprises a ventilation slot plate, wherein the ventilation slot plate comprises a slot plate teeth part and a slot plate yoke part; the slot plate teeth part and the slot plate yoke part are both provided with triangular slots; and each slot is provided with a supporting sheet which is matched with the slot in shape. The ventilation slot plate for a direct current motor has the advantages that the structure is simple, the parts has strong universality, and the action effect is obvious. Under the condition of ensuring the safety and reliability of motor, the specific geometric distribution of triangular support sheets, instead of the traditional bar type support plates, is used, thereby greatly increasing the ventilation area and further improving the cooling efficiency and motor property.

Description

The direct current machine ventilation channel plate

Technical field

The present invention relates to the direct current machine ventilation channel plate, specifically a kind of ventilation channel plate that is applied on the big-and-middle-sized air cooling radial ventilated cooling motor can promote the motor internal air circulation, improves motor performance thereby take away heat, belongs to technical field of motors.

Background technology

In large and medium-sized direct current machine, for realizing the purpose of motor internal cooling, usually cooling system is installed in the motor top, cooler by advance/circulation of air of air outlet takes away the motor heat.Can directly the heat of core portion be taken away for making air, obtain better cooling effect, the method that adopts usually in the prior art is: on armature core, every a segment distance radial ventilation ditch is set, settle ventilation channel plate in the ventilation ducts, form a radial ventilation system.Cooling air carries out heat exchange by the circulation in the radial ventilation ditch, thereby reaches the purpose of cooling armature core.

In the existing ventilation channel plate structure, its fagging is a long strip type substantially, comprises the I-steel of long straight shape and " Z " shape support sheet of elongation, and support sheet cross section is a rectangle.Yet along with the development of electromechanics trade, power of motor is increasing, and the ratio of capacity and volume is increasing, and is more and more higher to the requirement of turbulence noise aspect, and traditional ventilation channel plate is in the demand that is difficult to satisfy motor aspect flow resistance and the cooling effectiveness.

Summary of the invention

In order to address the above problem, the present invention has designed a kind of direct current machine ventilation channel plate, by using triangle support sheet to increase draught area, prevent that the motor internal temperature rise is too high, turbulence noise is excessive, effectively improve the motor cooling effectiveness, thereby reduce the ventilation noise and improve motor performance, simple in structure, easy to use, part universality is strong.

Technical scheme of the present invention is: the direct current machine ventilation channel plate, comprise ventilation channel plate, described ventilation channel plate comprises frid tooth portion and frid yoke portion, and described frid tooth portion and frid yoke portion are equipped with the triangle slot, and described slot is provided with the support sheet that matches with the slot shape; Use the special geometric of triangle support sheet to distribute rather than traditional long strip type fagging, increase draught area greatly, thereby improve cooling effectiveness and motor performance.

Described frid tooth portion centerline is equipped with slot, and frid yoke portion all is arranged with slot near the tooth root place, and frid yoke portion is positioned on the center line of frid tooth portion and is equipped with slot.

Described support sheet stream interface body is an isosceles triangle, and the inboard of fixed point end frontage and airiness frid, and support sheet fixed point end helps reducing windage down, thereby improves cooling effectiveness and motor performance.

Described support sheet is by slot location and be welded on the ventilation channel plate, and the support sheet is by slot location and welding, effectively prevents to support the sheet problem that comes off.

The invention has the advantages that: simple in structure, part universality is strong, action effect is obvious, under the condition that guarantees motor safety and reliability, use the special geometric of triangle support sheet to distribute rather than traditional long strip type fagging, increase draught area greatly, the scheme that support sheet tip is arranged down, help reducing windage, thereby improve cooling effectiveness and motor performance, the support sheet is by slot location and welding, effectively prevents to support the sheet problem that comes off.

Embodiment

Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.

Shown in Fig. 1-5, the direct current machine ventilation channel plate comprises ventilation channel plate 1, and described ventilation channel plate 1 comprises frid tooth portion 2 and frid yoke portion 3, described frid tooth portion 2 and frid yoke portion 3 are equipped with triangle slot 4, and described slot 4 is provided with the support sheet 5 that matches with slot 4 shapes.

Described frid tooth portion 2 centerline are equipped with slot 4, and frid yoke portion 3 all is arranged with slot 4 near the tooth root places, and frid yoke portion 3 is equipped with slot 4 on frid tooth portion 2 center lines.

Described support sheet 5 stream interface bodies are isosceles triangle, and the inboard of fixed point end frontage and airiness frid 1.

Described support sheet 5 is located and is welded on the ventilation channel plate 1 by slot 4.

Support sheet 5 and slot 4 are one-to-one relationship, and its quantity and arrangement can be adjusted according to the size and the structure of ventilation channel plate 1, and the stress in the time of still must satisfying the silicon steel sheet closed assembly bears requirement.

Ventilation channel plate structure of the present invention makes traditional bar shaped fagging (as shown in Figure 6) into the triangle fagging, has increased the wind path area.Its tip is installed in the slot repeatedly the fixed form of face welding down, not only greatly reduces the wind path windage, reduces turbulence noise, and more firm difficult drop-off.

It should be noted that at last: the above only is the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
