Description

Vorrichtung zum Ausgleich der Dehnungen des Zylinders von Kolbenkraftmaschinen. Im nachfolgenden soll eine Vorrichtung zum Ausgleich der Dehnungen des Zylinders von Kolbenkraftmaschinen, insbesondere von Hochdruckdampfmaschinen, beschrieben werden, durch welche die Wärmespannungen beseitigt werden, die dadurch entstehen, daß der Zylinder mit dem Gestell verbunden ist. Nach der Erfindung erfolgt die Verbindung unter Einschaltung an sich bekannter beweglicher Zwischenglieder, z. B. Pendelstützen oder Kugel- oder Rollenlager, während zur Zentrierung an den Verbindungsstellen drei oder mehr .Gleitstücke, z. B. Federkeile, radial angeordnet werden. Die Vorrichtung ergibt den Vorteil, daß die Berührungsflächen zwischen Zylinder und Gestell ein Minimum sind, so daß das Gestell von den Wärmewirkungen des Zylinders zum größten Teil entlastet ist.Device to compensate for the expansion of the cylinder of piston engines. In the following a device to compensate for the expansion of the cylinder of piston engines, in particular of high pressure steam engines, described which remove the thermal stresses that arise as a result, that the cylinder is connected to the frame. According to the invention, the connection is made with the involvement of known movable intermediate members such. B. Pendulum supports or ball or roller bearings, while for centering at the joints three or more .Gleitstück, z. B. spring wedges are arranged radially. The device gives the advantage that the contact surfaces between the cylinder and the frame Are minimum, so that the rack from the thermal effects of the cylinder to the greatest Part is relieved.

In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt. Nach Abb. i besteht .der Zylinder aus zwei Teilen i und 2, die durch Schraubenbolzen 3 miteinander verbunden sind. Um beim Warmwerden des oberen Deckels 4 zusätzliche Wärmespannungen in dem durch diesen. Dekkel gehenden Teil des Schraubenbolzens 3, der im unteren Deckel befestigt ist, zu vermeiden, ist der Deckel 4 nicht unmittelbar gegen .den Bund 6 d'es Schraubenbolzens 3 gezogen, sondern es ist dazwischen eine starke Feder 7 eingeschaltet, so daß sich die Wärmedehnung des Flansches zwangsfrei einstellen kann.In the drawing is an embodiment of the subject matter of the invention shown. According to Fig. I. The cylinder consists of two parts i and 2, which go through Screw bolts 3 are connected to one another. To when the top lid warms up 4 additional thermal stresses in the through this. Cover going part of the screw bolt 3, which is attached in the lower lid, the lid 4 is not immediate against .den collar 6 d'es screw bolt 3 pulled, but there is one in between strong spring 7 switched on, so that the thermal expansion of the flange is free can adjust.

Die Verschraubung des Zylinders mit dem Gestell 8 erfolgt mittels Schraubenbolzen 9 unter Einschaltung von Pendelstützen io, von denen nach Abb. 2 je zwei neben jedem Schraubenbolzen angeordnet sind.The cylinder is screwed to the frame 8 by means of Screw bolts 9 with the inclusion of pendulum supports io, of which according to Fig. 2 two are arranged next to each screw bolt.

Damit die Pendelstützen und( Schraubenbolzen der Dehnung des Zylinders in radialer Richtung nachgeben können, sind sie im Zylinder und Gestell mittels Kugelpfannen i t und kugeliger Unterlegstücke 12 gelagert. Zur Aufnahme von Seitenkräften und Drehmomenten und zur Zentrierung des Zylinders im .Gestell sind an den Verbindungsstellen drei oder mehr Federkeile 13 o. dgl. angeordnet, und zwar sind nach der Abbildung vier um 9o° gegeneinander versetzte Keile vorgesehen.So that the pendulum supports and (screw bolts of the expansion of the cylinder can give way in the radial direction, they are in the cylinder and frame means Ball sockets i t and spherical shims 12 mounted. For absorbing lateral forces and torques and for centering the cylinder in the .Gestell are at the connection points three or more spring wedges 13 o. The like. Arranged, namely according to the figure four wedges offset from one another by 90 ° are provided.

Bei dem Ausführungsbeispiel nach Abb. 3 und 4 sind bei sonst gleichem Aufbau anstatt der Pendelstützen Kugellager 14 verwendet, die im vorliegenden Falle konzentrisch zu den Schraubenbolzen 9 angeordnet sind.In the embodiment of Fig. 3 and 4 are otherwise the same Structure instead of the pendulum supports used ball bearings 14, which in the present case are arranged concentrically to the screw bolts 9.

Der Flansch zur Befestigung des Zylinders am Gestell ist an den Befestigungsstellen möglichst dünn ausgeführt, damit nicht durch seine Wärmedehnung gefährliche Zusatzspannungen in axialer Richtung in die Schraubenbolzen 9 gebracht werden. Es ließe sioh aber :beispielsweise auch hier eine Ausführungsform mittels Feder o. dgl. wie bei der Verschraubung 3 des oberen Zylinderteils anwenden.The flange for fastening the cylinder to the frame is at the fastening points Made as thin as possible so that there are no dangerous additional stresses due to its thermal expansion are brought into the screw bolts 9 in the axial direction. But it would be fine : For example, here, too, an embodiment by means of a spring or the like. As in the Use screw connection 3 of the upper part of the cylinder.
