SZ series gearboxes for conical twin-screw extruder are special driving units matched with conical twin-screw rod extruder. It consists of two parts, namely, the reduction box and the distribution box. After reducing speed and increasing torque of the motor, it outputs the motive power to the distribution box, then drives the double output shafts (the included angle is the same with that of twin-screw rods) via a pair of small conical spiral gears with driving ration of 1:1,thus to drive screw rods to rotate outward with different direction.

1.There are involute cylindrical gearbox, which data and structure are optimally designed by the computer.

4.The maximum input speed of the gearbox is normally not larger than 1500 rpm.

-45 ℃ before starting.
