SZ系列錐形雙螺桿擠出機齒輪箱
SZ Serial Gearbox for Conical Twin-Screw Rod Extruder

一、概述
    SZ系列錐形雙螺桿擠出機齒輪箱是與錐形雙螺桿塑料擠出機配套的專用傳動裝置。該齒輪箱由減速箱與分配箱兩部份組成，可將電機動力經(jīng)減速增扭后，輸出至分配箱，再通過分配箱一對1：1傳動比的小錐角螺旋齒輪，驅(qū)動雙出軸（兩軸夾角與兩螺桿夾角相同），帶動螺桿以異向外旋的方式運轉(zhuǎn)。

    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.

訂貨須知
      1、齒輪箱所用潤滑油牌號N220-N320中級壓齒輪油。
      2、齒輪箱及分配箱采用循環(huán)水冷卻，冷卻水溫度不高于30度。
      3、兩箱體應安裝于同高度的平面上，分配箱的長軸外花鍵插入齒輪箱輸出軸花鍵孔時，在地腳螺母松開的情況下，檢查兩箱體底面與安裝平面間間隙，必要時作適當調(diào)整，保證齒輪箱輸出軸與分配箱長軸同軸。安裝完畢后，手動檢查，要求各部件間轉(zhuǎn)動靈活，無卡滯現(xiàn)象。
      4、螺桿與分配箱輸出花鍵軸同軸度直接影響分配箱齒輪及軸承壽命的長短，安裝時應拆下花鍵套用百分表檢查花鍵軸的徑跳，用塞尺檢查螺桿與分配箱花鍵軸端面間接觸是否良好，消除誤差。
      5、在運作過程中，如出現(xiàn)局部軸承部位過熱，或有異常噪音，應停機檢查，排出故障后方可運行。
