  • the at least one indentation extends beyond the stator in the axial direction, the region projecting beyond the stator projecting beyond the at least one groove in the radial direction and / or in the circumferential direction. In this way, an axial positioning and / or fixation of the stator is achieved in the housing. It is also advantageous if the housing is single-walled or multi-walled, in particular double-walled.
  • the multi-walled housing has the advantage that the structure-borne sound transmission from the stator is reduced to the housing.
  • the at least one recess is advantageously produced by an oscillating on the housing reciprocating pusher, which is moved for example on an elliptical path. This has the advantage that the material is mechanically stressed only slightly during cold forming, so that even brittle or cracking prone materials can be processed.

  • the housing 1 may be surrounded by a cooling jacket, not shown, wherein a cooling medium between the wall of the housing 1 and the cooling jacket is guided along. Since the wall of the housing 1 is completely closed, that is, for example, is not pierced by holes, no leakage in the wall of the housing 1 can occur.

Abstract

L'invention concerne des dispositifs de fixation d'un stator dans un boîtier, avec un boîtier et avec un stator disposé dans le boîtier, le boîtier comprenant sur son pourtour plusieurs indentations pour le serrage du stator sur le boîtier. Les indentations génèrent de cette façon une liaison par friction au moyen de laquelle un couple prédéfini peut être transmis par le stator sur le boîtier. Avec le dispositif selon l'invention, en plus de la liaison par friction, une liaison par complémentarité de forme est atteinte du fait qu'il est possible de transmettre un couple du stator sur le boîtier plus grand que celui selon l'état de la technique. Selon l'invention, il est prévu, sur le pourtour du stator (2), au moins une gorge (9) dans laquelle s'encastre l'indentation (8) du boîtier (1).
