摘　　要：概述了国内外多螺杆挤出机传动系统的原理、结构、性能、应用现状和市场情况,分析了其发展趋势。着重论述了高扭矩双螺杆挤出机传动系统的技术发展。并对多螺杆的参数优化以及推力轴承系统的设计技术进展进行了介绍。介绍了双向双螺杆挤出机用传动箱,新型止推装置可替代传统的止推包。提出了用变频控制技术改造螺杆挤出机传动系统的必要性, 同时闸述了改造方法和效果。Summarized the principle, structure, performance, present application and market of driving system of the multi crew extruder domestic and abroad. Analyzed the developing trend. Mainly discussed the technical development of the driving system with high torque twin screw extruder, Intro- duced the optimized parameter of the multi screw and the design technique progress of thrust bearing system. Introduced the driving gear box for bi-directlonal twin screw extruder, the new thrust device can instead of the traditional thrust fit, Put forward the necessity to use frequency conversion control tech- nique to modify the driving system of screw, meanwhile described the modified method and effect.
