Abstract

The utility model provides a splicing structure for armature fanning strips of large and medium DC motors. The splicing structure comprises armature fanning strips, wherein an armature slot, a key slot and a screw rod hole are punched on each armature fanning strips; a plurality of armature fanning strips are spliced to form an integral annular armature punching sheet; seams are formed between adjacent armature fanning strips; two integral annular armature punching sheets are laminated up and down to form a whole; seams of the two integral annular armature punching sheets are mutually staggered; matching wedges are mounted in the key slots; and screw rods are mounted in the screw rod holes. The laminated armature fanning strips are positioned through matching wedges and combined through the screw rods, so that radial and axial displacement of the armature fanning strips are effectively controlled and the integrity of the whole armature core is improved.

Description

The splicing construction of big-and-middle-sized direct current machine armature fanning strip
Technical field
The utility model relates to a kind of splicing construction of armature fanning strip of large and medium DC motor, is particularly useful for the above direct current machine of height of center Z1000.
Background technology
The armature stamping of the DC motor below the armature external diameter φ 1250mm because cylindrical is smaller, can directly adopt the full circle punching out.But when the armature external diameter surpasses φ 1250mm, just can't adopt the full circle punching out, can only adopt the fanning strip splicing, carry out iron core with fanning strip and press-fit.Fanning strip splicing complex procedures, present manufacturer is difficult to grasp to its key technology, and the globality of the armature core after press-fiting is generally not good.
The utility model content
The purpose of the utility model is to provide a kind of splicing construction of big-and-middle-sized direct current machine armature fanning strip; Utilize a full circle of fanning strip splicing becoming; Through two-layer intersection up and down, and screw rod, wedge effectively control the radial and axial displacement of armature fanning strip, improves the globality of whole armature core.
The technical scheme of the utility model is following:
A kind of splicing construction of big-and-middle-sized direct current machine armature fanning strip; Comprise the armature fanning strip; Punching out has armature slot, keyway and screw hole on the said armature fanning strip, and a plurality of said armature fanning strip splicings become a full circle shape armature stamping, between every adjacent armature fanning strip seam are arranged; Two said full circle shape armature stampings laminate up and down and are one, and the seam of two full circle shape armature stampings staggers each other; Cooperate wedge to be installed in the said keyway, screw rod is installed in the said screw hole.
Its further technical scheme is: each full circle shape armature stamping is made up of 6 armature fanning strips.
Its further technical scheme is: the external diameter of the full circle shape armature stamping that is spliced into is more than or equal to 1440mm.
The useful technique effect of the utility model is:
The utility model can satisfy external diameter and laminate needs greater than the armature stamping punching out of φ 1250mm, and intersects, effectively controls the radial and axial displacement of armature fanning strip closing screw rod and wedge through seam, improves the globality of whole armature core.
Description of drawings
Fig. 1 is the structural representation of single armature fanning strip.
Fig. 2 is the structural representation that the armature fanning strip laminates into the utility model.
Embodiment
For enabling further to understand the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited about the utility model.
As shown in Figure 1, armature fanning strip 1 is the component units of the armature stamping of large and medium DC motor, and punching out has armature slot 2, screw hole 3 and keyway 4 on the said armature fanning strip 1.
As shown in Figure 2, the armature stamping of large and medium DC motor comprises the some armature fanning strips 1 that surround a full circle shape.In the present embodiment, full circle shape armature stamping is spliced into by six armature fanning strips 1, between every adjacent armature fanning strip 1 seam 7 is arranged.In the present embodiment, the external diameter of the full circle shape armature stamping that is spliced into is more than or equal to φ 1440mm.When carrying out punching and laminate, two full circle shape armature stampings are laminated up and down be one, the seam 7 of bilevel full circle shape armature stamping staggers each other.The armature fanning strip that laminates; Adopting the cooperation wedge to position, adopt screw rod to carry out handle closes: wherein six keyways 4 are packed into and are cooperated wedge 5; The circle location is used in when remaining keyway 4 laminates as iron core; Last whole iron core adopts screw rod 6 tight closing again, accomplishes press-fiting of armature core, improves the globality of whole armature core.
Above-described only is the preferred implementation of the utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of the basic design that does not break away from the utility model, all should think to be included within the protection range of the utility model.
