Hey extruder builders: Looking for a compact drive for your single-screw machines?
Henschel America Inc. of Green Bay, Wis., and K&A Knoedler GmbH of Ostfildern, Germany, say they have what you need.
After a year of sales in Europe, the companies are introducing a drive that is half the size of a standard drive, at lower costs. It also puts out torque from the lowest to fast speeds.
The new drive consists of four, three-phase alternating-current motors arranged around one bigger gear. The gear has a hollow shaft in the middle and a thrust bearing in the front. The extruder screw can be directly connected to the hollow shaft.
Another advantage of the hollow shaft is the ability to remove the screw through the drive, or to access the screw for cooling or heating purposes.
Henschel America also announced a new series of economically priced gearboxes for single-screw extruders.
