Abstract
Eine Zylindertrommel für hydrostatische Kolbenmaschinen hat mehrere in die Zylindertrommel (1) eingebrachte Zylinderbohrungen (5), in denen zur Aufnahme von Kolben Laufbuchsen (7) angeordnet sind, deren Innenwände (14) die Gleitflächen für die Kolben ausbilden. Die Zylindertrommel (1) ist in einem Gehäuse angeordnet, in deren Innenraum ein Leckvolumen ausgebildet ist. An dem Umfang der Zylindertrommel (1) sind Kühlrippen (10) angeordnet. A cylinder drum for hydrostatic piston machines has a plurality of cylinder bores (5) which are made in the cylinder drum (1) and in which bushes (7) are arranged for receiving pistons, the inner walls (14) of which form the sliding surfaces for the pistons. The cylinder drum (1) is arranged in a housing, in the interior of which a leak volume is formed. Cooling fins (10) are arranged on the circumference of the cylinder drum (1).
