sZ锥双螺杆挤出机专用齿轮箱
Special Decelerator for sZ Conic Double-screw Extruder
一、原理及概述Principle and overview
SZ锥双螺杆挤出机传动装置是与锥双螺杆塑料挤出机配套的专用机械传动装置，该装置可把主电机的动力经过传动箱减速增扭后输出至分配箱长轴，长轴再通过一对1:1传动比的小锥角螺旋齿轮，带动短轴。长.短轴以螺杆相同的夹角，以异向外旋的方式带动螺杆挤出成型。传动箱采用硬齿面标准设计.齿轮经渗碳淬火磨齿，精度达6级，所有油封皆采用进口产品.传动箱和分配箱内皆配有冷却水管，用于润滑冷却。由于产品齿轮精度高，噪音低，承载能力强，轴承配置相对传统产品有新的改进，因而其总体性能指标优于现行产品。
SZ cone double-screw extruder gearing is a special mechanical driving device matched with conicdouble-screw plastic extruder. This advice decelerates and increases the torque of the power from master motor through gearbox before exporting it to the long shaft of distribution box that drives short shaft through a slender cone screw gear with drive ratio of 1:1, long shaft and short shaft drive screw at the same angle as screw to extrude and mould in the mode of different direction and outward turning. Gearbox is designed with hard tooth surface standard,and gear wheel is treated with carburation and quenching and grinding to achieve the precision of class 6,all of the oil seal is imported products,both gearbox and distribution box are equipped with cooling pipe for lubrication cooling Gear wheel is of high precision,low noise,and high carrying capacity ,resulting in a relatively improved bearing configuration in comparison with traditional one, therefore, the general performance is superior to that of current products.
