发明名称 Thermal Growth Compensating Extrusion Screw Assembly
摘要 An improved extrusion assembly is disclosed which better adapts to thermal changes resultant from the transport of high-temperature extrudate. An extrusion screw present in the assembly includes a hollow portion. A biasing member is disposed in the hollow portion. When the assembly is transporting high-temperature extrudate, the biasing member's included Belleville washer component compensates for the thermal expansion and contraction of the extrusion screw.
