摘　　要：介绍了同向双螺杆挤出机的发展方向以及国内齿轮箱的发展现状,分析了将功率分流式传动结构应用于高扭矩齿轮箱的优势;介绍了齿轮修型技术提高齿轮强度以及实现均载的应用,螺杆间隙和槽深比对挤出机性能的影响,以及提高螺杆轴抗扭能力的两种方法。The direction of the co-rotating twin screw extruder and the current situation of the gearbox is introduced. The advantage of the bilateral gear symmertrical driving system which is used in the high torque gearbox is analyzed. The gearshape modification technology which is used to improve the strength of the gear and achieve uniform load, the influence on extruder of the screw clearance and the groove depth, two way to improve the torsional strength of the shaft are introduced.
