| Zusammenfassung: | The machine (10) has housings (13) comprising end shields (13.1, 13.2). A cooling body (53) is attached with a fastening element i.e. screw, comprising an insulating part at one of the end shields. The insulating part comprises a sleeve part, which runs between two front-sided arranged flat surfaces. The insulating part is made of material e.g. elastomer, rubber, natural rubber or silicone rubber, with elastic properties. The flat surfaces cover the cooling body in an overlap. A through-hole is formed in the insulating part, and extends from one of the flat surfaces to the other flat surface.
Die Erfindung bezieht sich auf eine elektrische Maschine (10), insbesondere einen Drehstromgenerator. Diese umfasst ein Gehäuse (13) mit mindestens einem Lagerschild (13.1, 13.2) sowie mindestens einen Kühlkörper (53). Der mindestens eine Kühlkörper (53) ist mit mindestens einem ein Isolierteil (62) aufweisenden Befestigungselement (60) an einem der Lagerschilde (13.1, 13.2) befestigt. |
