Parallel twin-srew counter-rotation

This counter-rotating extruder gearbox is based on our proven DOS design with a torque factor up to 44 Nm/cm³.

The DURUMAX® T1MAX extruder gearbox of Henschel Antriebstechnik offers to the extrusion manufacturer the newest state of the art technology. In comparison to the TPM 3 DOS-V series it offers an up to19 % higher torque.

Outstanding Characteristics :

  • High "power density" with all used center distances
  • Modular and suitable design
  • High efficiency by reduction of rotary parts
  • Exceptionally high operational safety
  • Torque ratings determined by the customers and market requirements
  • Excellent price-performance ratio

The technical concept of the T1MAX 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 similar gear pairs (like a double helical gear) with optimized design.

The gearbox can be driven directly by a motor or with belt at the input shaft. In the multi-stage helical gearbox the speed is reduced while the required torque is created. This torque is transmitted in the distribution gearbox to the two counter-rotating output shafts. The axial forces resulting from the extrusion process are absorbed by thrust bearings inside the thrust bearing housing.
