Gear reducer for twin screw extruder
Double shaft extruder gears have been built by PIV Drives since 1984 for a variety of applications in the plastics and food industries and have been put into operation around the world to our customers' complete satisfaction. This extremely compact and appealing design means that we are able to provide a modern, high-power gear in small installation spaces.
The gears are case hardened and ground and optimised with a profile correction according to the load, which consists of bending and torsion. A very good noise behaviour is achieved through a high contact ratio.
The axial forces which occur during extrusion from the process part are safely absorbed in the gear with tandem bearings and self-aligning roller thrust bearings.
