SZ Series Twin Screw Plastic Extruder Gearbox

SZ series Conical Twin Screw Extruder Gearbox

Product Description

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.

Product Feature

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

2.The gears are made of top-quality high strength low carbon alloy steel after carbon penetrating, quench and teeth grinding. It has high hardness on teeth surface, large bearing ability, small noise, smooth operation and high driving efficiency.

3.The material of the distribution box is nodular grate casting iron and the gears have high-strength ground teeth, in which snake-shaped cooling water pipes are distributed.

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

5.The temperature in work environment is -10℃-45 ℃.When temperature is lower than 0℃,the lubricant oil should be preheated to + 10℃ before starting.
