Like single screw extruder gearboxes they are also employed in the plastic extruder machinery and the rubber extruder machinery.

Now, you must be wondering what exactly differentiates the single screw extruder gearbox from the twin screw extruder gearbox.

Well, in twin screw extruder gearbox two screws are being utilized which work in counter-rotating movements. So, designing them can be a bit tricky because it requires dimension that will deliver high torque in both the screws.

We are widely popular in the market as the manufacturer and supplier of Twin screw extruder gearboxes designed to enhance the high torque and high speed conditions or output rate.

On design basis it is quite similar to the twin screw extruder gearboxes. However, it is equipped with heat dissipation and oil lubrication systems which offers high output rate even under high loading force conditions. And secondly, the axial thrust which are incorporated in the twin screw extruder gearboxes are supported with the help of axial roller swivel type thrust bearing which are coupled to the thrust bearings which are again arranged in tandem arrays.

Design of the twin screw extruder gearboxes

• They are cast in graded iron.
• They have bearings that are cast in set alloys.
• Inner walls of the gearboxes are coated with epoxy and they are lubricated with the help of the high performance oils.
• They have helical teeth of different dimension which increases the efficiency of the machinery.
• They have internal cooling coils which aid in the heat dissipation mechanism of the gearboxes.
• The gear unit has been distributed into four different sections which are reduction gear unit, distributor gear unit, adaptor housing and the thrust housing which are basically connected to the extruder machinery.

Advantages of using the twin screw extruder gearboxes

There are multiple reasons which clearly signify why should choose this extruder gearbox for your plastic extruder or rubber extruder machinery.

So, here I will be listing some of the advantages of using the twin screw extruder gearboxes which are as follows:

• Their gearbox structure dimensions ensure the maximum possible rotational movement between the two screws.
• They have high torque
• High output rate.
• High heat dissipation capacity
• High power transmission capacity
• Thrust bearings or more specifically axial thrust bearings which are tandemly arranged.
• Built in lubrication and heat dissipation systems.
