    Fig. 1 The invention relates to an electric stator housing with air cooling. The stator casing of an air-cooled electric machine is known, including a C11y sheet lining with rail No.1 1 L .i However, this casing does not provide the necessary reliability to connect the plating with the stator core. The strongest cover of the invention is the stator casing of an electric machine with air cooling. Uncovered in the form of a sheathing intended for mounting to the stator core, having corrugated cooling fins projecting in the radial direction, elongated in the axial direction 2. Sheeting can only be made in the axial direction only slightly longer than the stator core, so that in addition to serving only; viH cooling the sheathing in the axial direction on both sides, it is necessary to have one part of the casing. With the advent of a new technology in which the molded parts of the casing were directly replacing the "1 elongated sheet skin with cooling fins, this skin should be partially or fully self supporting, in addition to its cooling function. However, to achieve the necessary contact between the surfaces for heat removal and transfer of forces, the connection is made by means of expensive welding with the surface of the stator core, which is a disadvantage of the known construction. The aim of the invention is to increase reliability. This goal is achieved by the fact that, in the stator thrust of an electric machine with air cooling, made in the form of a sheet plating designed for landing on a stator core with corrugated fins, the radial directional guide, curved in the axial direction, has an inner surface of the sheet plating the convexity of the axial Bpa .aeifflv5 provided the strength necessary for pressing the core, with elements at both ends of the casing preventing the expansion of the diameters of the edges at nressovke core. At that, when the stator core is pressed in the stator casing, the inner surface of the stator casing cover parts located between the cooling fins evenly sits rigidly throughout its surface on the stator core and the stator housing and the stator core practically form one node, in which optimal heat transfer is ensured, and the stator housing fully complies with the requirement for being self-supporting. The convex stator housing is accomplished with a preliminary stress, which, when pressing in the stator core, provides a satisfactory almost uniformly distributed pressure throughout the contact surface from the stator housing to the stator core. In this case, the elements that prevent the expansion of the diameters of the edges during the pressing-in of the core are made in the form of rings connected to the sheeting, for example, by welding. At least one of these rings should be located inside the casing. In addition, at least one of said rings may be located outside the casting. The bases of the ribs are preferably welded together; It is preferable to provide a casing provided with paws, one part of which is attached to the ribs and the other is intended to be connected directly to the core. FIG. 1 schematically shows a stator housing with a stator, an axial section; in fig. 2 - stator casing, axial section; on fig.Z stator, axial section; in fig. 4 a stator housing with support rings, axial section in FIG. 5 ib - two different embodiments of the stator of an electric machine with air cooling, front view; Fig.7 paw in the casing and the stator core, the cut. 3 The casing I of the stator with the core 2 of the stator of the electric air-cooled electric motor is formed from sheet plating with a bolted number of molded cooling fins 3 elongated axially and protruding in a radial direction located at a distance from each other around the circumference of the circle, moreover, between the cooling fins are parts of the casing 4 for mounting on the surface of the stator core. The cooling fins 3 can be open (figure 5) or closed (figures and shapes. For mounting the stator casing 1 and the stator core 2, the latter is pressed into the preformed stator casing 1. For this inner surface 5 of the sheathing is made convex axial direction, the inner diameters of the edges at both ends of the sheet plating correspond to the outer diameter of the stator core 2. At the same time, the sheet plating at both ends is provided with stiffening elements which, when pressed into the stator core 2 in l Preventing the lining prevents the diameter of the edges from expanding. The preformed stator casing 1 has a caNbiM of a prestressing of such a kind that the inner surface of the parts of the casing 4 lying between cooling fins 3, when pressed, fits perfectly evenly and firmly its surface to the surface of the core 2 84 of the stator, due to which the set requirements for heat transfer ability and osprinimaemym moments. In addition, the described technology allows the disassembly and reassembly of the stator housing 1 with the stator core 2. These stiffeners can be close to the edge by welding points 6 in the base of the npu along the entire height of the ribs of the coolers 3. The stiffeners are formed by the outer support ring 7 and the inner bearing ring 8, and naturally either two outer or two inner bearing rings could also be used. These support rings serve simultaneously B .ch. the carrier of the protective shields of the machine's bearings (not shown). To install the paws 9, one cooling edge passes through the perimeter of the circumference of the stator casing 1 and the machine paw is welded there, passing through the stator casing 1, with the stator core 2. This is only one of a whole range of possibilities for the design and installation of foot structures. The described stator casing is usually molded from a single sheet, with the cooling fins mechanically performed using punches or chased stamps. Due to the corresponding tension of these tools, it is possible to produce the described convexity of the inner surface of the casing in one working operation.
