Gear mechanism for twin-screw extruders

摘要

The invention relates to a gear mechanism for twin-screw extruders with a drive pinion for two gear trains, which each drive one of the two screw shafts, each gear train including a power branching means and the summation of the power of the respective power branches taking place by toothings, arranged axially offset on the screw shafts, and torsion elements being provided, which compensate for the different torsions of the screw shafts. To be able to perform uniform power distribution to all four gear trains, a particular angular position of the screw shafts with respect to one another having to be maintained, it is envisaged according to the invention to perform the setting of the toothing by means of three releasable connections so exactly that there is a good division of power.
