SZ系列锥形双螺杆挤出机齿轮箱
SZ Serial Gearbox for Conical Twin-Screw Rod Extruder
一、概述
SZ系列锥形双螺杆挤出机齿轮箱是与锥形双螺杆塑料挤出机配套的专用传动装置。该齿轮箱由减速箱与分配箱两部份组成，可将电机动力经减速增扭后，输出至分配箱，再通过分配箱一对1：1传动比的小锥角螺旋齿轮，驱动双出轴（两轴夹角与两螺杆夹角相同），带动螺杆以异向外旋的方式运转。
SZ Serial Gearbox for Conical Twin-Screw Rod Extruder is a special driving unit matched with conical twin-screw rod extruder.it consists of two parts,namely,the reduction box and the distribution box.After reducing speed and increasing torque of the motor,it outputs the motive power to the distribution box,then drives the double output sharts(the included angle is the same with that of twin-screw rods) via a pair of small conical spiral gears with driving ratio of 1:1,thus to drive screw rods to totate outward with different direction.
二、产品特点 Features of Product：
1、齿轮箱齿轮采用渐开线圆柱齿轮，其参数、结构经过计算机优化设计。
2、减速箱齿轮材料采用优质高强度低碳合金钢，经渗碳、淬火处理，采用磨齿工艺，齿面硬度高，承载能力大，噪音小，运转平稳，传动效率高。
3、分配箱箱体材料为球铁，齿轮为磨齿高强度齿轮，内部布有蛇形冷却水管。
4、齿轮箱输入最高转速一般不大于1500r/min.
5、工作环境温度－10－+40℃，当环境温度低于0℃时，启动前润滑油应加热到+10℃。
1、There are involute cylindrical gears in the gearbox,which data and structure are optimally designed by the computer.
2、the gears are made of top-quality high-strength low carbon alloy steel arter carbon penetrating,quench and teeth grinding.It has high hardness on teeth surface,large bearing ability,small noise,smooth operation and high driving efficiency.
3、The material of the distribution box is nodular graphite casting iron and the gears have high-strength ground teeth.in which snake-shaped cooling water pipes are distribubted.
4、the maxmum input speed of the gearbox is normally not larger than 1500 rpm.
5、The temperature in work enviroment is -10℃～-45℃.When temperature is lower than 0℃,the lubticant oil should be preheated to +10℃ before starting.

订货须知
1、齿轮箱所用润滑油牌号N220-N320中级压齿轮油。
2、齿轮箱及分配箱采用循环水冷却，冷却水温度不高于30度。
3、两箱体应安装于同高度的平面上，分配箱的长轴外花键插入齿轮箱输出轴花键孔时，在地脚螺母松开的情况下，检查两箱体底面与安装平面间间隙，必要时作适当调整，保证齿轮箱输出轴与分配箱长轴同轴。安装完毕后，手动检查，要求各部件间转动灵活，无卡滞现象。
4、螺杆与分配箱输出花键轴同轴度直接影响分配箱齿轮及轴承寿命的长短，安装时应拆下花键套用百分表检查花键轴的径跳，用塞尺检查螺杆与分配箱花键轴端面间接触是否良好，消除误差。
5、在运作过程中，如出现局部轴承部位过热，或有异常噪音，应停机检查，排出故障后方可运行。
