Extruder e.g. planetary-gear extruder, for use during processing of plastics, has sleeve-shaped or ring-shaped sections that are hold on carrier, where carrier is interlocked with sections and carrier in connection with extrusion drive

摘要

The extruder has a planet roller module (5) with a central spindle (11) that consists of sleeve-shaped or ring-shaped sections. The sleeve-shaped or ring-shaped sections posses toothing formed as involute toothing. The sleeve-shaped or ring-shaped sections are provided with circulating planet spindles in an interference manner. The sleeve-shaped or ring-shaped sections are hold replaceably on a carrier, where the carrier is interlocked with the sections and the carrier in connection with an extrusion drive.
