Abstract

Bei einem Exzenterantrieb (10) für mindestens einen Kolben (12) einer Kolbenpumpe mit einer angetriebenen Welle (14) und einem die Welle umgebenden Lager (16), an dem der mindestens eine Kolben (12) radial zur Welle (14) abgestützt ist, ist das Lager (16) als Gleitlager mit einer metallischen Gleitfläche (18) und einer nichtmetallischen Gleitfläche (20) gestaltet.

Figure imgaf001
In an eccentric drive (10) for at least one piston (12) of a piston pump with a driven shaft (14) and a bearing (16) surrounding the shaft, on which the at least one piston (12) is supported radially to the shaft (14), the bearing (16) is designed as a sliding bearing with a metallic sliding surface (18) and a non-metallic sliding surface (20).
