The invention relates to electrical engineering, in particular to the technology of manufacturing electrical machines.

The purpose of the invention is to simplify the manufacturing technology and increase reliability.

FIG. Figure 1 shows the scheme for making the workpieces of the stops on the bearing shield, the stator in the housing (the arrangement of the parts before their articulation, fastening elements not shown); in fig. 2 - view A on figo 1; in fig. 3 is a diagram of the implementation of the workpieces of the stops on the bearing shield, the stator without the housing (the arrangement of the parts before their articulation, the fastening elements are not shown) in FIG. 4 is a diagram of the implementation of the blanks of the stops on the stator, in particular on its case (the arrangement of the parts before their articulation, the fastening elements are not shown).

Example 1 (Fig. 1 and 2). At the end of the bearing shield 1 of al

spike shield 1. (shown by horizontal hatching).

Example 3 (figure 4). Blanks

2 radial stops 3 are made on the end of the cast body 4 of aluminum alloy. The process of forming radial stops 3 is similar to that shown in Example 1, while the stops

3 body 4 cover the cylindrical surface of the bearing shield 1.

The proposed method of assembling an electric machine makes it possible to simplify the process of forming radial stops by plastic deformation of the workpieces for said stops, made, for example, at the same time as the part during its manufacture (casting). This, in turn, provides a solid fastening of the radial stops on the face of the part and their reliable contact with the male surface of the part being joined, which increases the operational reliability of attaching the shield to the stator

mini alloy in the process of casting an electric machine. In addition, billets 2 for radial stops 3 are made. The length q of billets 2 exceeds the thickness B of the body 4 of the stator 5 G In the stator 5 there is a rotor 6. Along the perimeter of the billets 2 are grooves 7 to remove the deformed material. After centering the rotor 6 relative to the stator 5, the parts to be joined (bearing shield 1 and body 4) are exposed to an axial force P sufficient to deform the workpiece in the area of its face contact with the body 4. In this case, part of the length of the workpiece 2 (shown

The radial stops made by the proposed method allow multiple disassembly of the electric machine in repair plots with a subsequent assembly, in which the centering of the rotor relative to the stator is performed without using special equipment and equipment at the radial pins performing the function of the centering elements.
