新聞資訊 >> 新型人字齒輪減速機傳動裝置-

   針對同步齒輪減速機傳動裝置存在的不足,開發(fā)了雙螺桿泵新型人字齒輪減速機無齒輪套傳動裝置。該裝置采用人字齒輪,取消了同步齒輪減速機傳動裝置中的齒輪固定套,使電動機的傳動扭矩直接由平鍵傳給主動齒輪,再由主動齒輪帶動從動齒輪實現(xiàn)同步旋轉(zhuǎn)。該裝置在傳動過程中無軸向力產(chǎn)生,大大提高了雙螺桿泵軸承的壽命,同時還可減少雙螺桿泵配件數(shù)目,降低零部件的加工精度,消除原帶齒輪套傳動裝置的從動軸不能與主動軸同步轉(zhuǎn)動的種種弊病,使傳動的同步性能更加可靠,雙螺桿泵的工作效率更加穩(wěn)定。這種新型裝置現(xiàn)場應用效果很好,具有廣闊的的推廣應用前景。
   同步齒輪減速機齒輪傳動裝置簡述雙螺桿泵由主動和從動2根螺桿組成,每根螺桿軸上有2件可以旋轉(zhuǎn)的左右螺旋套,形成雙吸泵的基本結(jié)構(gòu)。液體由中央流入泵體后均分成2路流向軸兩端。2對螺旋套會隨軸末端一對同步齒輪的轉(zhuǎn)動進行嚙合旋轉(zhuǎn)。當螺桿旋轉(zhuǎn)時,其螺旋面會打開形成腔室,隨著腔室容積.
   減速機配件加工中心現(xiàn)貨提供：齒輪加工,齒輪馬達,蝸輪蝸桿,無級變速機,齒輪換向器,蝸輪減速機,絲桿升降機,微型擺線針輪減速機,精密行星減速機,螺旋錐齒輪減速機,斜齒輪硬齒面減速機,減速機配件加工.
