150mm Screw Diameter High Torque Gearbox For Twin Screw Extruder Machine
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.
----Double drive design enables the B axis to be driven by two gears without increasing the tooth width.
----Optimal structure and complex assembly lead to the cost rise.
----All bearings are sourced from global recognized brands,so output torque is more stable.
---Streamlined design,the end of gearbox cover can be opened,easy to install and replace.
