Advantageous This is because the foot part is simply attached to the stator housing attach.

at Another preferred embodiment, the stator housing a cylindrical shell body on, on the outside of which cooling fins are formed, which extend in the axial direction parallel to each other and are arranged in four groups, with the ends of the cooling fins each group lie approximately in a plane, with boundary cooling ribs each group approximately substantially in a right Angle to each other and the housing attachment section between or on the boundary cooling ribs is arranged and extends in the axial direction of the stator housing. Advantageous is that a shape of the stator housing used multiple times is.

at Another preferred embodiment extends the threaded hole in the radial direction of the stator housing. The advantage here is that the threaded hole well with the mating surfaces interacts.

at Another preferred embodiment, the stator housing a Fußanbaubereich, which two housing mounting sections includes, which are arranged one behind the other in the axial direction and the foot part two the housing mounting portions corresponding sections with the corresponding mounting sections aufweißt. The advantage here is that the foot part safely is held on the stator housing.

In a further preferred embodiment, the stator housing on four Fußanbaubereiche, wherein the extension lines of the Cut the axes of the threaded holes in the central axis of the stator housing at 90 degrees. The advantage here is that the foot is easy to attach to the various threaded holes.

Further Advantages emerge from the subclaims. The invention is not limited to the combination of features of the claims. For the expert, further meaningful combination possibilities arise Claims and / or individual claim features and / or Features of the description and / or figures, in particular the task and / or by comparison with the state the technical task.

The Invention will now be described with reference to embodiments Referring to the drawing explained in more detail. It shows purely schematically:

1 a three-dimensional view with partial section of a stator housing with a fastening device according to the invention;

2 a side view of a foot part for a fastening device according to the invention;

3 a cut through the in 2 shown foot part; and

4 a top view of the in 2 shown foot part.

In the 1 is a fastening device according to the invention 10 on a stator housing 12 shown. The stator housing 10 has a cylindrical shell-shaped body 36 are formed on the outer surface of cooling fins. The cooling fins 36 extend in the axial direction over the outer surface and are aligned parallel to each other arranged in 4 groups. Free-standing ends of the cooling fins 36 Each group is approximately in one plane. Each group is made up of two boundary cooling ribs 38 limited. The boundary cooling ribs 38 of two adjacent groups are arranged substantially perpendicular to each other.

On these boundary cooling ribs 38 is a foot-growing area 40 arranged. The foot-growing area 40 includes a housing attachment section 20 , The housing attachment section 20 includes a mating surface 22 and another counter surface 26 and a threaded bore designed as a blind hole 28 , The counter surface 22 and the other counter surface 26 are perpendicular to each other. A central axis of the threaded hole 28 is at an angle of preferably 45 degrees to that of the mating surface 22 and the other counter surface 26 spanned levels. Preferably, two housing attachment sections 20 in the axial direction of the stator housing 12 one after the other in the foot-growing area 40 arranged.

In total, there are four foot areas 40 arranged on the stator housing.

To the foot-growing area 40 is by means of a screw as a fastener 15 a foot part 14 attached. For this is the fastener 15 through a hole 23 in the foot part 14 guided and in the threaded hole 28 screwed. There are also clip devices, rivets or other releasable as insoluble fasteners 15 conceivable.

The foot part 14 has an attachment section 16 on. The attachment section 16 includes two bearing surfaces 18 which run parallel to each other. Additional points the attachment section 16 another support surface 24 on. In the mounted state is one of the two bearing surfaces 18 on the opposite surface 22 on and the further contact surface 24 on the other counter surface 26 , By the arrangement of the acreage according to the invention 18 and the other acreage 24 in interaction with the counterface 22 and the other counter surface 26 Can the foot also on the stator housing 12 be attached to one of the two bearing surfaces 18 on the other counter surface 26 rests and the further contact surface 24 on the opposite surface 22 rests. Thus, the foot part 14 at all four foot areas 40 of the stator housing 12 be grown in two different positions. This allows a listing of the stator housing 12 in many different positions with only a single embodiment of the foot part 14 , This allows for easier storage and also safe mounting of the foot part 14 ,

For easier releasable attachment of the foot part 14 at the stator 12 , indicates the attachment section 16 two holes 23 on. The two holes 23 are perpendicular to each other and intersect in the interior of the foot part 14 , which is otherwise solid. An axis of the holes 23 forms an angle of 45 degrees to a single bearing surface 18 and the third bearing surface 24 , From the mounted state of the stator housing 12 opposite end of the bore 23 is designed with a larger diameter and thus forms a countersunk head section 30 for receiving a screw head 32 the screw. As in 3 shown, the respective countersunk section ends 30 before drilling 23 cut at right angles.

The foot part 14 has a substantially prismatic body with triangular cross section. At the ends are, as well as in 4 shown in continuation of an outer surface of the ground Body mounting plates molded. The mounting plates have holes or slots. By means of the slots and holes is the foot part 14 attachable to a corresponding device.

The bearing surface 18 and the third bearing surface 24 as well as the counter surface 22 and the other counter surface 26 are preferably reworked material removal in order to achieve a defined surface roughness and planarity.

The stator housing 12 and the foot part 14 are preferably produced as castings, in particular from a globular gray cast iron or nodular cast iron.
