Abstract

The invention discloses a stator pressing ring structure which comprises a stator pressing ring. Outward extending axial binding rods integrally made with the stator pressing ring are arranged on the end face of the stator pressing ring, the end face of the stator pressing ring is provided with an annular slope, the binding rods are distributed on the end face of the stator pressing ring according to needs of windings at binding fixing ends, and an insulation tape is wound on each binding rod and subjected to dipping paint curing treatment. The stator pressing ring structure is high in strength and reliability and capable of effectively fixing preformed windings.

Description

The stator pressing ring structure

Technical field

The present invention relates to relate to a kind of support stator pressing ring of traction electric machine, the support stator pressing ring of particularly high-power motor-car and locomotive traction motor.

Background technology

The support of the High power Traction motor of single-machine capacity more than 500kW that Foreign High Power railway motor-car and locomotive use; The general Welding Structure that adopts both sides casting trim ring to add middle steel plate; After stator punching laminates, in support and form iron core, be referred to as to call out frame by weld all around.The railway locomotive of China's introduction at present and the High power Traction electric machine stand manufacturing technology of motor-car also adopt this mode of production.

At present; What the stator winding of these motors adopted is the moulding winding, and the moulding winding overhang generally all need be fixed on stator flange or the support, adopts usually the winding overhang colligation on the insulation supporting mechanism; The insulation supporting mechanism is fastened on the stator pressing ring with securing member; This traditional fixed form need be used supporting mechanism and the securing member that insulating material is made, and has bad mechanical strength, and the many costs of part count are expensive; The supporting mechanism that insulating material is made is damaged easily, securing member shortcoming such as come off easily.

Summary of the invention

The object of the present invention is to provide a kind of intensity height, good reliability, and can be effectively the fixing stator pressing ring structure of moulding winding.

In order to achieve the above object, technical scheme of the present invention is: a kind of stator pressing ring structure, comprise stator pressing ring, and the end face of stator pressing ring is provided with the overhanging axial binding bar of processing one with stator pressing ring.

Has annular slope on the end face of said stator pressing ring.

Said binding bar is ten, and is evenly distributed on the end face of stator pressing ring.

After adopting said structure; Because the end face of stator pressing ring is provided with the overhanging axial binding bar of processing one with stator pressing ring, is wound with insulating tape on the binding bar, and the dipping lacquer cured; Therefore can be effectively the fixing end of moulding winding; And owing to be to process one with the stator pressing ring end, strength ratio used the fastening fixture intensity of securing member higher in the past, better reliability.

Description of drawings

Fig. 1 is a front view of the present invention;

Fig. 2 is the right view of Fig. 1.

Embodiment

The embodiment that provides below in conjunction with accompanying drawing does further detailed explanation to the present invention.

Referring to Fig. 1, shown in 2, a kind of stator pressing ring structure comprises stator pressing ring 1, and the end face of stator pressing ring 1 is provided with the overhanging axial binding bar 1-1 that processes one with stator pressing ring 1.Be wound with insulating tape on the binding bar, and the dipping lacquer cured.

Referring to shown in Figure 1,, has annular slope 1-2 on the end face of said stator pressing ring 1 in order in installation process, to damage later on.

Referring to shown in Figure 1, in order to fix the moulding winding overhang, said binding bar 1-1 is ten, and is evenly distributed on the end face of stator pressing ring 1.

Referring to Fig. 1, shown in 2, when the present invention uses, stator pressing ring 1 is fixed on the out frame; Then with the end banding of moulding winding on ten binding bar 1-1 of stator pressing ring 1, binding bar 1-1 and stator pressing ring 1 are cast as one, and are wound with insulating tape on the binding bar 1-1; And the dipping lacquer cured, the effective fixing end of moulding winding, and owing to be to be cast as one with stator pressing ring 1-1 end; Strength ratio used the fastening fixture intensity of securing member higher in the past, better reliability.
