Patentiert im Deutschen Reiche vom 23. Juni 1914 ab.Patented in the German Empire on June 23, 1914.
Es ist bekannt, Zylinderdeckel von Verbrennungskraftmasctiinen in ihrer Gesamtheit in zwei vollständig getrennte Teile zu zerlegen, von denen der eine — äußere — zur Aufnähme der Arbeitsdrücke bzw. der Schraubenkräfte bestimmt ist und daher entsprechend kräftig ausgebildet wird, während der zweite — innere ■— in erster Linie zur Wärmeabführung dient und mit Rücksicht auf diesen ZweckIt is known, cylinder covers of internal combustion engines to be dismantled in their entirety into two completely separate parts, one of which - outer - for recording the working pressures or the screw forces is determined and is therefore made correspondingly strong, while the second - internal ■ - serves primarily to dissipate heat and with regard to this purpose
ίο seine Gestaltung erhält.ίο preserves its design.
Es war nun bisher üblich, diese beiden Teile aus gegossenem Material herzustellen, was aber den Nachteil hatte, daß in dem fertigen Stück sogenannte Gußspannungen auftreten, die zu einem Reißen der Wandungen und damit zu schweren Betriebsstörungen Veranlassung gaben.It was now customary to manufacture these two parts from cast material, but this had the disadvantage that so-called casting stresses in the finished piece occur that cause the walls to tear and thus cause serious malfunctions Gave cause.
Um diesen Mißstand zu vermeiden, wird gemäß der vorliegenden Erfindung der innere Teil aus Schmiedeeisen hergestellt, und um mit Sicherheit völlige Spannungsfreiheit zu erreichen, setzt man ihn aus zwei Stücken zusammen, von denen das eine aus einer dicken massiven Platte durch Dreh- und Fräsarbeit herausgearbeitet wird. Das andere Stück besteht aus einer einfachen Deckplatte; beide Stücke werden außerdem ausgeglüht. Es hat dieses Herstellungsverfahren den Vorzug, daß die Wandstärken mit äußerster Genauigkeit innegehalten werden können, daß sie genau meßbar sind, und daß man sicher ist, nur einwandfreies Material zu verwenden, da etwaige Fehler bei der Bearbeitung sofort zu Tage treten werden.In order to avoid this inconvenience, according to the present invention, the internal Part made of wrought iron, and to be sure that it is completely tension-free you put it together from two pieces, one of which is made up of one thick solid plate is carved out by turning and milling work. The other Piece consists of a simple cover plate; both pieces are also annealed. This manufacturing process has the advantage that the wall thicknesses are extremely accurate can be paused, that they are precisely measurable, and that one is sure is to use only flawless material, as any errors in processing immediately will come to light.
In der Zeichnung ist in Fig. 1 im Querschnitt und in Fig. 2 in einer Draufsicht die Erfindung beispielsweise für den Zylinderdeckel einer einfachwirkenden stehenden Maschine dargestellt.In the drawing is in Fig. 1 in cross section and in Fig. 2 in a plan view Invention, for example, for the cylinder cover of a single-acting stationary machine shown.
Es ist α der äußere, zur Aufnahme der Betriebsdrücke und sonstigen Beanspruchungen dienende Teil, welcher aus dem üblichen Material — Gußeisen oder Stahlguß — kräftig hergestellt und durch die Schrauben b mit dem eigentlichen Zylinderkörper fest verbunden ist. Der innere, zur Wärmeabführung dienende Teil besteht aus zwei Einzelstücken, dem Unterteil c und dem Oberteil d. Zwischen beiden befindet sich der Kühlraum e, der durch im Unterteil c angeordnete Rippen f in schmale Kanäle zerlegt ist, durch welche das Kühlwasser mit großer Geschwindigkeit hindurchfließen muß. Dadurch, daß die Platte d jederzeit leicht und vollständig abgenommen werden kann, ist eine gute Reinigungs- und Besichtigungsmöglichkeit des Wasserraumes gewährleistet.It is α the outer part serving to absorb the operating pressures and other stresses, which is made of the usual material - cast iron or cast steel - and is firmly connected to the actual cylinder body by the screws b. The inner part, which is used to dissipate heat, consists of two individual pieces, the lower part c and the upper part d. Between the two is the cooling space e, which is divided into narrow channels by ribs f arranged in the lower part c, through which the cooling water must flow at high speed. The fact that the plate d can be easily and completely removed at any time ensures that the water area can be easily cleaned and inspected.
Der Unterteile ist, wie oben bereits erwähnt, aus einer kräftigen Platte von Schmiedeeisen durch Dreh- und Fräsarbeit entstanden; die erforderlichen Durchdringungen für die Ventile und ebenso die zur Führung des Kühlwassers dienenden Rippen sind bei der Bearbeitung ausgespart.The lower part is, as already mentioned above, Made from a strong plate of wrought iron by turning and milling work; the necessary penetrations for the valves and also for the guidance of the cooling water Serving ribs are cut out during processing.
Der obere Teil d hat die Form einer einfachen Platte, die auf den unteren Teil c aufgelegt ist. Durch eingedrehte Dichtungsflächen, in, die geeignete Dichtungsringe z. B. aus Gummi eingelegt sein können, wird eine Abdichtung des Kühlraumes gebildet.The upper part d has the shape of a simple plate which is placed on the lower part c. By screwed sealing surfaces in, the suitable sealing rings z. B. can be inserted from rubber, a seal of the cooling space is formed.
Auf den Rippen f liegt der obere Deckel glatt auf, da an dieser Stelle eine besondere Dichtung nicht erforderlich ist.The upper cover rests smoothly on the ribs f , since a special seal is not required at this point.
ίο Die Verbindung des wärmeabführenden Teiles c, d mit dem kräfteaufriehmenden Teil a geschieht einerseits durch die Schraubenbolzen g, andererseits durch rohrförmige Anker h, welche in den Durchdringungen i für die Ventile im unteren Teil c eingreifen und die Ventileinsätze umschließen.ίο The connection of the heat-dissipating part c, d with the force-raising part a is done on the one hand by the screw bolts g, on the other hand by tubular anchors h, which engage in the penetrations i for the valves in the lower part c and enclose the valve inserts.
Bei der Ausbildung dieser Anker h sowohl wie der Bolzen g ist darauf Rücksicht genommen, daß sich der gesamte untere wärmeabführende Teil ' gegenüber dem kräfteauf-' nehmenden Teil radial ausdehnen kann. Die Hohlanker h wie die Schraubenbolzen g sind daher mit Spiel durch den äußeren Teil a hindurchgeführt. Auch die beiden Hälften des wärmeabführenden Teiles c, d sind derartig miteinander verbunden, daß eine Ausdehnung des unteren, den hohen Temperaturen im Verbrennungsraum ausgesetzten Teiles c gegenüber dem plattenförmigen Oberteil d möglich ist. Hierzu sind die in der Zeichnung ersichtlichen Spielräume k um die Dichtungsstellen herum gegeben.In the design of this armature h as well as the bolt g , care is taken that the entire lower heat-dissipating part can expand radially with respect to the force-absorbing part. The hollow anchors h and the screw bolts g are therefore passed through the outer part a with play. The two halves of the heat dissipating part c, d are connected to each other such that expansion is the high temperatures in the combustion chamber exposed part c d possible relative to the plate-shaped upper part of the bottom. For this purpose, the clearances k shown in the drawing are given around the sealing points.
Die Kühlwasserführung ist bei der dargestellten Konstruktion so gewählt, daß ein ganz bestimmter Strömungsweg eingehalten werden muß, indem der Kühlraum in einen fortlaufenden schmalen, langen Kanal aufgelöst ist, worin sich entsprechend der großen Wassermenge und dem geringen Querschnitt eine die Kühlwirkung fördernde hohe Wassergeschwindigkeit einstellt. Zur richtigen Wasserführung dienen auch die besonders befestigten, strichpunktiert dargestellten Einsatzstücke n. The cooling water flow is chosen in the construction shown so that a very specific flow path must be maintained by the cooling space is dissolved into a continuous narrow, long channel, in which a high water speed promotes the cooling effect is set according to the large amount of water and the small cross-section. The specially fastened inserts n shown in dash-dotted lines also serve to ensure the correct water flow.
Die Wasserzuführung geschieht beispielsweise bei I, die Wasserabführung bei m. The water supply takes place, for example, at I, the water drainage at m.
Die vorbeschriebene Art der Ausbildung eines Zylinderdeckels bzw. des inneren wärmeabführenden Teiles desselben kann natürlich in ganz ähnlicher Weise außer, wie gezeichnet, bei einfachwirkenden, stehenden Maschinen auch bei doppeltwirkenden und liegenden Maschinen verwendet werden,, und die Vorteile werden bei jeder Verwendungsart dieselben bleiben.The above-described type of formation of a cylinder cover or the inner heat dissipating one Part of it can of course be done in a very similar way except, as shown, in the case of single-acting, stationary machines can also be used with double-acting and horizontal machines, and the advantages will remain the same for every type of use.
