Description
Durch die Entwicklung und Anwendung von hohen Temperaturen ist man bei Kraftmaschinen gezwungen, die Lagerkörper, die früher meist mit dem Maschinengehäuse zusammengegossen waren, von diesem zu trennen, um die durch unmittelbare Verbindung oder Berührung ermöglichte bequeme Übertragung der Wärme vom heißen Gehäuse auf das Lager zu verhüten und dadurch Verziehungen des Lagergehäuses sowie ein Anwärmen des Lagerschmiermittels weitgehendst zu vermeiden.Developing and applying high temperatures is what makes you feel at power machines forced the bearing body, which used to be mostly cast together with the machine housing were to be separated from this in order to facilitate the convenient transfer made possible by direct connection or touch to prevent the heat from the hot housing on the bearing and thereby distortions of the bearing housing and heating the bearing lubricant to a large extent avoid.
Es tritt aber noch eine große Wärmestrahlung vom Turbinengehäuse ausgehend auf, welche ihrerseits das Lagergehäuse, die darunter befindliche Grundplatte und das Fundament einseitig erwärmt. Dadurch treten Dehnungen auf, welche eine Verschiebung der Achse des Zylinders zur Lagermitte sowie auch gefährliche Spannungen in diesen Teilen verursachen können.However, there is still a great deal of heat radiation emanating from the turbine housing, which in turn the bearing housing, the underlying base plate and the foundation heated on one side. This causes strains, which shift the axis of the cylinder to the center of the bearing as well can also cause dangerous voltages in these parts.
Nun ist es bekannt, Schirme als Wärmeschutzvorrichtung in einer den zu schützenden Körper (Kessel, Trockentrommel) umgebenden luftverdünnten Hülle anzuordnen sowie zum Schütze von mit einem Kreiselverdichtergehäuse in unmittelbarer Berührung stehendem Lagergehäuse im Innern des letzteren gekühlte Flächen vorzusehen. Beide .Anordnungen sind jedoch nicht geeignet, die obengenannten Nachteile zu beseitigen.It is now known to use screens as a thermal protection device in one of the to be protected Body (boiler, drying drum) surrounding air-diluted shell to be arranged and to protect with a centrifugal compressor housing in direct contact standing bearing housing in the interior of the latter to provide cooled surfaces. Both However, arrangements are not suitable for eliminating the above-mentioned disadvantages.
Letztere sollen vielmehr durch die vorliegende Erfindung behoben werden. Dieselbe besteht darin, daß zwischen Lagerbock und Maschinengehäuse eine auch das Fundament abdeckende Schirmwand außen angeordnet ist, deren Wärme von einem Kühlstrom abgeleitet wird. Rather, the latter is intended to be remedied by the present invention. Same consists in the fact that between the bearing block and the machine housing there is also a foundation covering screen wall is arranged outside, the heat is derived from a cooling flow.
In der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform beispielsweise dargestellt.In the drawing, the subject matter of the invention is, for example, in one embodiment shown.
Abb. ι zeigt die Anordnung der Schirmwand in seitlicher Ansicht und Abb. 2 in Vorderansicht.Fig. Ι shows the arrangement of the screen wall in a side view and Fig. 2 in Front view.
α stellt das Lager mit dem zugehörigen Lagerbock, und Fundament dar, b das Gehäuse der Kraftmaschine und c die Schirmwand; letztere trennt Lager und Gehäuse derart voneinander, daß der unmittelbare Wärmeübergang durch Bestrahlung unterbunden und eine unzulässige Erwärmung von Lagerbock und Fundament vermieden wird. α represents the bearing with the associated bearing block and foundation, b the housing of the prime mover and c the screen wall; the latter separates the bearing and the housing from one another in such a way that the direct heat transfer through irradiation is prevented and inadmissible heating of the bearing block and foundation is avoided.
Die Schirmwand selbst ist zweckmäßig hohl und wird von einer Kühlflüssigkeit durchströmt, welche die durch Strahlung aufgefangene Wärme der Wand ableitet. Die Schirmwand selbst kann hierbei auch aus wärmeisolierendem Baustoff bestehen oder auch mit dem Lagerbock oder der Grundplatte aus einem Stück hergestellt sein.The screen wall itself is expediently hollow and is cooled by a cooling liquid flows through, which dissipates the heat captured by radiation from the wall. the The screen wall itself can also consist of heat-insulating building material or also be made in one piece with the bearing block or the base plate.
