SHTDN Twin Screw Extruder Gearbox Introduction

Twin Screw Gearbox adopting latest standard ISO1328,the precision of cylindrical gear of spherical involute, and combining our long term experience and specialty of twin screw extruder, SHTDN gearboxes are meticulously designed with top advanced designing ideas in the world for co-orientated rotating twin screw extruder, with entirely independent Intellectual Property Rights.
The gears are made of carburizing steel of high-strength alloy of good quality by carburizing and quenching for teeth, of which all the gear grinding processes are finished by imported gear grinding machines. Gear parameters are optimized and specially designed for the characteristics of twin screw extruder, reducing stress concentration on root of gear and improving gear surface conditions. We have improved gear intension of flexural fatigue, fatigue strength and ratio of wide diameter. We have also adopted the latest designing idea and technology of heating treatment for the structure of gears, thereby ensured gears from uniformity of precision and strength.
