Fixation arrangement for fixing stator at housing of electrical rotary machine, has blank holder element having necked-down bolt screwed into screw thread to pre-tension against housing for exerting pressing force on stator via case

摘要

The fixation arrangement has housing (3) in which recess (19) is formed, and which has holder (11) to exert pressing force on stator (5) to fix stator at housing. A screw thread (25) is formed in recess spaced from surface (23) of housing. A blank holder element (13) is formed in holder. The blank holder element has case (15) whose length is smaller than depth of recess. The blank holder element has necked-down bolt (17) which is screwed into screw thread in axial direction to pre-tension against housing for exerting the pressing force on the stator via case.
