Power divider with two pair of gears (comparable with double helical gears) counter-rotation, reaches a torque factor of up to 40 Nm/cm³.
The DURUMAX® TPM 3 DOS-V extruder gearbox of Henschel Antriebstechnik offers the extrusion manufacturer high technology on the newest state of the art technology. In the global market the TPM 3 DOS-V has asserted itself against the hardest competition and is meanwhile the most widely used counter-rotating extruder gearbox.
The technical concept of the TPM 3 DOS-V series consists of a reduction gearbox and a distribution gearbox. Both gearbox modules are connected by the thrust bearing housing.
In contrast to the TPM 3 series the distribution of the torque occurs with the DOS gears in the distribution step with two pairs of gears like a double helical gear.
The gearbox can be driven directly by a motor or with a belt at the Input shaft. In the multi-stage helical gearbox, the speed is reduced and 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.
