Parallel Twin-Screw Co-rotation

Co-rotating power divider with two gear pairs (comparable with double helical gears) reaches a torque factor of up to 24 Nm/cm³ 

Based on the approved TPM 3-DOS-V series of counter rotating twin shaft extruder gearboxes Henschel developed the DURUMAX® TGE 3-DOS series for co-rotating extrusion in 1997. The range has been continuously extended. 

Outstanding Features:

  • High "power density" at all center distances

  • Modular and practical design

  • High efficiency due to a minimum of rotating parts

  • Exceptionally high operational safety

  • Torque ratings determined by the customers and markets requirments

  • Excellent price-performance ratio

The technical concept of the TGE series consists of a reduction gearbox and a distribution gearbox. Both gearbox modules are connected by the the thrust bearing housing.

Similar to the TPM 3 DOS-V series the distribution of the torque is done by two pairs of gears (like a double helical gears) with optimized design.

The gearbox is driven by a motor directly at the input shaft. In the one-stage helical gearbox the speed is going to be reduced while the required torque is created. This torque is transmitted in the distribution gearbox to the two co-rotating output shafts. The axial forces coming from the extrusion process will be absorbed by thrust bearings inside the thrust bearing housing.
