(54) METHOD OF MANUFACTURING A DISK ANCHOR ELECTRICAL MACHINE

Invented 1e relates to the technology of manufacturing electric matshn and can be used in electrical engineering about 1.

A known method of manufacturing a multi-layer winding of electrical machines, through which a wire is wound onto a template to secure it from displacement, with an adhesive substance, forms a preform on a gear mandrel to obtain windings. Then, after removing the zigzag from the mandrel, flat elements are attached to the end surfaces of the workpiece and rotate relative to each other around the axis of the winding to the required one. angle l.

The disadvantage of this method is the great complexity of the need to secure the workpiece when it is wound on a template.

A method of manufacturing a winding of a hollow cylindrical core is also known, consisting in winding a winding wire onto a template with an elongation in the form

loops for attaching to the collector ;, gluing the active parts of the winding to the insulating material and placing the template with the winding in the press, this one layer of the winding is fixed on the fixed part and the other is shifted along the first one to lay the winding in plane 2 ..

The disadvantage of this method is more complicated manufacturing process, determined by the need for gluing the active; parts of the winding to iznp imoHHoiviy base and the use of sophisticated technological equipment for laying the winding in the plane.

The purpose of the invention is the simplification of the manufacturing of the core.

The goal is achieved by winding on an annular pattern consisting of two parallel

20 spaced discs with grooves for unloading the active parts of the winding, and shifting the active parts of the winding to the pitch and stacking it in the PGK plane is worn out by turning the discs in opposite directions with their simultaneous approach. . Figure 1 shows collected disc measles; in fig. 2 - scheme of winding the winding on the pattern; in fig. 3 and 4 are variants of the location of the end surfaces of the Kojib target pattern. The following is about the same. .. The winding is made on a winding pattern, voyenoyney form of two yrylly arranged annular disks .1 with grooves 2 for placing the active parts of the winding. The disks are located at a given distance from each other using spacers 3, thus forming a ring pattern dgsh winding drum winding. . The number of spacers 3 is established, based on the condition of ensuring the tightness of the ring AIR template; winding wire winding 4 with wire 5. After winding. spacers can be removed through the holes 6 in the discs. The coils of the winding 4 are wound with a wire 5 on an annular pattern in a spiral with simultaneous conclusions 7. At the same time, the active sides of coil 8 of the helix are placed on opposite sides of the ring pattern in the slots 2, which allows winding of the conductors without fixing each conductor from the displacement. The front portions of the winding 4 can be laid in the shoulders 9, and the leads 7 are connected to the current collector (contact rings or the collector). The specified first pitch of the drum winding core is obtained by rotating the discs 1 of the template relative to each other in opposite side with their simultaneous approach. After turning the turns of the winding core, the disks 1 of the template and the frontal parts are fixed from the relative displacement, for example, by pouring the compound. When making the end surfaces of the template of the rings 10-13 (Fig. 4), it is possible by changing the distance in the axial direction, respectively, of the rings 10 and 13, 11 and 12 (Fig. 3) and 1O and 13 (Fig. 4) to obtain the required lengths of the frontal parts . In addition, when arranging the pattern disks, as shown in FIG. 4, receive obmu-ku with a triangular shape of a coil. To obtain the required length of the outer frontal parts, the device 14 is used. The efficiency of the proposed method is to simplify the manufacturing of cores by winding the windings of the windings into the grooves of the template, while the protrusions from the corrugations not increasing the core thickness increase its axial rigidity and consequently, reliability ... Fo rumula of a b ete n e Method of manufacturing a disk core electric machine, when the coorrm is wound onto a template with simultaneous stepwise conclusions, The coils are twisted from displacement, the active parts of the winding are shifted by a step size and placed in a plane, so that, in order to simplify the manufacturing process, winding is performed on a ring pattern consisting of two paralleleptic arranged discs with grooves to accommodate the active parts of the winding, and the shift of the active parts of the winding by the step size to placing it in a plane is made by turning the discs in opposite directions with their simultaneous approach.
