Blade press and extrusion unit gear box

The gearbox, a common product in the field of power transmission, can provide power transmission functions for wind power generation units and various mechanical processing industries. However, for each specific application scenario, the role played by the gearbox varies greatly, which directly leads to the specialization and division of the gearbox. 

In the field of plastic extrusion processing, the gearboxes of the pelletizing and extrusion units can be regarded as a very crucial core component. As the gearbox that connects the motor and the screw, its functions are manifested in several aspects: reduction, torque increase, changing the transmission direction, and power distribution, etc. Especially in the field of twin-screw extrusion, the gearbox needs to transfer the motor's torque to the two screws. Under the constraint of the center distance between the two screws, how to obtain a higher torque ratio while ensuring the long service life of the gearbox has become a difficult problem that the researchers and designers of gearboxes need to face.
