Description

Bearing support of electrical machines with a horizontal shaft The invention relates to a module for holding and receiving bearings, in particular of plain bearings, in electrical machines with a horizontal shaft.

So far, the - constructions differ from bearing brackets due to the different designs B (shield storage machines) and D (pedestal storage machines) according to DIN 42 950 considerably, so that depending on the embodiment, different bearing variants exist, which do not allow a uniform storage system. Hence the manufacturers forced by electrical machines, contrary to other rationalization efforts in terms of the stocks on offer and especially in terms of production, the different ones Bear in mind. The effort is therefore considerable.

Generally known are two types of shield storage machines (design B) of bearings, in particular slide bearings. The end shield hub is used for one to accommodate the plain bearing. The bearing is built directly into the machine. With the other type of storage, the plain bearing hangs between two fastened to the end shield Consoles, the bearing body at its feet at the level of the shaft axis with the Consoles is screwed.

The bearing is therefore attached to the electrical machine in this case. The disadvantage in both cases is that because of the location of the attachment of the bearing bracket access to the warehouse itself is difficult.

With pillow block machines (design D) the plain bearing is separate from the electrical machine is used as a pillow block bearing, with the feet of the bearing body are fastened to the foundation or base frame at the level of the machine base.

The invention is based on the object of specifying a module which for receiving and holding in particular slide bearings in the same way Can be used for types B and D according to DIN 42950 and is easily accessible of the bearing can be used with all known types of lubrication and cooling.

According to the invention, the object is given in the case of a module specified type solved in that the block above the machine base, but is attached below the shaft axis with feet on load-bearing surfaces.

On pillow block machines, the Feet plinths are provided as standing areas, while in the case of shield storage machines, the standing areas are formed by brackets arranged on the end shield. This applies to all types of construction uniformly applicable to the bearing block according to the invention, whereby with regard to significant rationalization of warehouse construction occurs. In addition, is through This design also means that the warehouse is easily accessible for maintenance and accessories in the case of shield storage machines also guaranteed. The invention is described below explained in more detail with reference to the drawing of exemplary embodiments. 1 shows a front and FIG. 2 a (partial) side view of a shield storage machine and FIG. 3 shows a front end and FIG. 4 shows a (partial) side view of a pillow block machine.

In a machine 1 in shield bearing design (Figures 1 and 2) is the block 3 is formed with 4 feet. According to the invention, the feet 4 are below the shaft axis 7, but above the machine base 8 on load-bearing surfaces, attached to the consoles 5 here. The consoles 5 are arranged on the end shield 2. This enables easy access to the warehouse itself.

According to Figures 3 and 4, the footprints of pedestal bearing machines formed by the base 6. With it are the feet 4 of the block 3 according to the invention, pinned below the shaft axis 7 of the machine 1 and the machine base area 8 and screwed. The feet 4 are advantageously permanently connected to the building block 3.
