ABSTRACT:
A drive unit for use with extrusion devices having counter-rotating double screws with parallel axes overcomes problems with loading of the bearings of such units.
The drive unit has an integral drive and output shaft with a pinion mounted on the output shaft. Two cog wheels or gears mesh with the pinion on opposite sides thereof and one of the cog wheels is mounted on a second output shaft. The other cog wheel acts as an intermediate gear wheel and both cog wheels mesh with an internally toothed hollow gear wheel or ring gear. By making the diameter of the intermediate gear wheel greater than the diameter of the pinion, conventional bearings can be used.
