Public limited company Brown Boveri 4 Cie., Baden / Schveiz Housing for electrical machines

The housing of rotating electrical machines is generally used formed by a cylindrical body provided with or without cooling fins, which still has fastening pieces such as E.g. tile can be added and on which one creates areas for attaching the terminal box or a sign.

In certain cases, these components are obtained in a single piece, especially if the housing is cast using the casting process (pressure, Mold, croning or sand casting) is made. In other Cases are the additional parts by welding, screw connection or in some other way close * eight that therefore from one other material than the housing can be.

The present invention relates to a polygonal, in particular rectangular, housing intended for electrical machines or square cross-sectional outer shape, characterized in that it is on at least one and preferably on all outer main surfaces T-shaped grooves for fastening various Has parts such as terminal box, feet, etc.

The attached drawing shows, as indicative but not restrictive examples, several types of execution of the invention as well as various possible uses.

- Figure 1 is the cross section of a housing.

- Figure 2 is a front view.

- Figure 3 and 4 are cross sections of housings for electrical Machines in a protected design or in a closed design with external cooling fins.

- Fig. 5 and 6 are cross-section details, which are two different Show uses of such housings.

The housings shown in Figure 1 to 4, which are in the casting process or produced in some other way (e.g. by welding) have two T-shaped grooves 1 and 2, 3 and 4, etc .; all grooves have theirs Opening to the outside for the insertion of screws or fastening hooks to allow.

The housing shown in Figure 3 differs from the one in Figure 1 in that it is protected; the one in Fig. 4 is closed compared to the solution in Fig. 1 and provided with cooling fins.

Figure 5 shows the use of the grooves to secure a terminal box, which can be achieved by engaging the hooks 6 and 7 in the lateral lower part of the groove happens. The stops θ and 9 are used for lateral guidance and support against the two Flanks of the T-slots in order to meet the toughest regulations with regard to the impact resistance of electrical machines. Figure 6 shows the use of the grooves to attach the housing directly to a wall 10 with the help of a nut 11, which is located in the wide area of the groove, as well as a threaded screw 12 which is screwed into the nut 11. Many other Applications are possible, especially the attachment of feet, which are attached to the housing in the same way as in Figure 6 will.
