SZ Conical twin-screw gear box

1.General Survey

SZ serial gearbox for Conical Twin-screw Rod Extruder is a special driving unit matached 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 gears with driving ration of 1:1, thus to drive screw rods to rotate outward with different direction.

2.Features Of Product

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

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

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

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

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