Description

Gegenstand der Erfindung ist eine Rollenführung für Kolben von Maschinen, insbesondere Brennkraftmaschinen. Sie bezweckt, den Kolben möglichst reibungslos im Zylinder zu führen.The invention relates to a roller guide for pistons of machines, in particular Internal combustion engines. Its purpose is to keep the piston in the cylinder as smoothly as possible to lead.

Gegenüber den bekannten Kolbenführungen, bei denen der Kolben an der Zylinderwand geführt wird, besteht die Erfindung darin, daß der Kolben von im unteren Teil ίο der Zylinderwand oder im Gehäuse entsprechend verteilt angeordneten Rollen- oder Kugellagern geführt wird.Compared to the known piston guides, in which the piston is on the cylinder wall is performed, the invention consists in that the piston of in the lower part ίο the cylinder wall or in the housing accordingly distributed roller or ball bearings is performed.

Der Kolben ist hierbei mit abgeflachten Laufflächen für Rollen-" oder Kugellager versehen. The piston is provided with flattened running surfaces for roller or ball bearings.

Die Abbildungen zeigen eine Ausführungsform des Erfindungsgegenstandes an einer Brennkraftmaschine, und zwarThe figures show an embodiment of the subject matter of the invention on a Internal combustion engine, namely

Abb. ι einen Achsialschnitt der Maschine undFig. Ι an axial section of the machine and

Abb. 2 einen Schnitt nach Linie A-B von Abb. i.Fig. 2 is a section along line AB from Fig. I.

Der Zylinder der Maschine besteht aus zwei Teilen 1,2, deren unterer, 1, in entsprechenden Aussparungen 3 die Kugel- oder Rollenlager 6 aufnimmt.The cylinder of the machine consists of two parts 1,2, the lower one, 1, in corresponding Recesses 3 the ball or roller bearings 6 receives.

Der Kolben 4 besitzt etwas kleineren Durchmesser als der Zylinder 1, 2 und dichtet in demselben mit dem Kolbenring 5 ab, der besonders verstärkt ist.The piston 4 has a slightly smaller diameter than the cylinder 1, 2 and seals in the same with the piston ring 5, which is particularly reinforced.

Die Kugel- oder Rollenlager 6 sind auf dem Umfang des Zylinders entsprechend verteilt und in zwei untereinanderliegenden Reihen angeordnet. Sie stehen etwas über die Innenoberfläche des Zylinders vor und gleiten an abgeflachten Laufflächen 7 des Kolbens. Die Achsen 8 zweier untereinanderliegender Kugel- oder Rollenlager 6 sind durch Lagerschienen 9 miteinander verbunden. Die letzteren sind in seitlichen Nuten 10 der Aussparungen 3 geführt und stehen unter dem Einfluß von die Kugel- oder Rollenlager 6 gegen die Kolbenwandung drückenden Federn 11. Dadurch wird eine stets feste Führung des Kolbens bewirkt und etwaige Größenveränderung des Kolbens infolge Wärmewirkung, Abnutzung usw. ausgeglichen.The ball or roller bearings 6 are distributed accordingly on the circumference of the cylinder and arranged in two rows one below the other. They protrude slightly above the inner surface of the cylinder and slide on flattened running surfaces 7 of the piston. The axes 8 of two lying one below the other Ball or roller bearings 6 are connected to one another by bearing rails 9. The latter are in side grooves 10 of the recesses 3 out and are under the influence of the ball or roller bearings 6 against the piston wall pressing springs 11. This ensures that the piston is always firmly guided and changes in size of the piston due to the effect of heat, wear, etc. compensated.

Durch die Anordnung der Rollen- oder Kugellager in der Zylinderwand wird neben dem der reibungslosen Führung noch der Vorteil erzielt, daß der Seitendruck des Kolbens durch die federnd angeordneten RoEen- oder Kugellager aufgefangen wird, so daß keine Abnutzung der Zylinderwand erfolgen kann.The arrangement of the roller or ball bearings in the cylinder wall is next to the smooth guidance still achieved the advantage that the side pressure of the piston is absorbed by the resiliently arranged RoEen or ball bearings, so that no Wear of the cylinder wall can occur.

Die erfindungsgemäße Anordnung der RoI-len- oder Kugellager kann bei Kolbenmaschinen aller Art, z. B. Brennkraftmaschinen, Dampfmaschinen, Pumpen usw., angewendet werden.The inventive arrangement of the roles or ball bearings can be used in all types of piston machines, e.g. B. internal combustion engines, steam engines, pumps, etc. applied will.
