Abstract

The present invention relates to an extruder arrangement having a drive motor and a switching gear (3) which is provided with an input shaft (21) and an output shaft (35). A double switching pinion (25) is arranged between first and second switching positions on the input shaft (21) in moving manner but not rotated against the input shaft. In each gear, a switching pinion (41, 42) is directly joggled to a shift gear (33, 33') of a central shaft (29, 29'), thereby rotating to the output shaft (35) from the central shaft.

Description

technical field

[0001] The invention relates to an extrusion device according to the preamble of claim 1 . Background technique

[0002] In practice, in extrusion plants of this type a gearshift transmission / reducer (hereinafter referred to as transmission) is used, on the input shaft of which transmission two pinions are mounted freely rotatable via rolling bearings, said pinions It is in constant mesh with a gear mounted non-rotatably on an output shaft parallel to the input shaft. Between the pinions arranged on the input shaft, a gear shift sleeve is non-rotatably connected to the input shaft by means of internal teeth. By displacement in the longitudinal direction of the input shaft, one or the other of the pinions can be connected to the input shaft in a rotationally fixed manner by means of the selector sleeve. The pinion, which is connected to the input shaft without the aid of a shift sleeve, performs a relative rotational movement with respect to the input shaft....
