The classical 3-shaft-concept with a torque factor of up to 22 N/cm³ for counter rotation.
The DURUMAX® TPM 3 gearbox was the first extruder gearbox with the 3-shaft power distribution concept and has already been in the market for more than 40 years. In spite of its long existence, this gearbox presently has a wide range of applications.
The technical concept of the TPM 3 series consists of a reduction gearbox and a distribution gearbox. Both gearbox modules are connected by the thrust bearing housing.
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.
