Abstract

Gegenstand der Erfindung ist ein Maschinenaggregat mit einer Wärmesperre, durch die ein während des Betriebes heißer Teil von einem kühlen Teil des Maschinenaggregates getrennt wird, wobei Befestigungsmittel die beiden Teile zusammenhalten und zwischen diesen Teilen ein Kraftfluß über ein oder mehrere kraftübertragende Elemente hergestellt wird.The invention relates to a machine unit with a heat barrier, through which a part hot from operation of a cool part of the Machine unit is separated, with fasteners the two parts hold together and between these parts a flow of force over one or more force-transmitting elements is produced.

Eine kurzbauende, wenig aufwendige Wärmesperre wird dadurch verwirklicht, daß der heiße Teil (1) und der kühle Teil (2) über einander benachbarte, mit Abstand zueinander angeordnete flanschartige Platten (5, 6) verfügen, die über ein oder mehrere kraftübertragende metallische Elemente (9, 16, 17, 18) miteinander verbunden sind, wobei die Verbindung über eine für die Kraftübertragung ausreichende minimale Querschnittsfläche erfolgt.

Figure 00000001
A short, inexpensive heat barrier is achieved in that the hot part (1) and the cool part (2) have adjacent, spaced-apart flange-like plates (5, 6) which have one or more force-transmitting metallic elements ( 9, 16, 17, 18) are connected to one another, the connection taking place over a minimum cross-sectional area sufficient for the force transmission.
