弧齒輪廠家

弧(hu)(hu)齒輪(lun)傳動(dong)(dong)(dong)(dong)的(de)特點是﹕(1)綜合曲(qu)率半徑比(bi)漸開線(xian)(xian)齒輪(lun)傳動(dong)(dong)(dong)(dong)大(da)(da)很(hen)多﹐其接觸強(qiang)度比(bi)漸開線(xian)(xian)齒輪(lun)傳動(dong)(dong)(dong)(dong)約高(gao)(gao)0.5～1.5倍﹔(2)兩輪(lun)齒沿嚙(nie)合線(xian)(xian)方向(xiang)的(de)滾(gun)動(dong)(dong)(dong)(dong)速度很(hen)大(da)(da)﹐齒面間(jian)易於形(xing)成(cheng)油膜(mo)﹐傳動(dong)(dong)(dong)(dong)效率較(jiao)高(gao)(gao)﹐一般可(ke)達0.99～0.995﹔(3)圓弧(hu)(hu)齒輪(lun)沿齒高(gao)(gao)方向(xiang)磨損均勻﹐且容(rong)易跑(pao)合﹔(4)圓弧(hu)(hu)齒輪(lun)無根切現象﹐故最(zui)小齒數可(ke)以(yi)少。但(dan)圓弧(hu)(hu)齒輪(lun)對(dui)中心距﹑切齒深(shen)度和螺旋角的(de)誤(wu)差敏感(gan)性很(hen)大(da)(da)﹐這三項誤(wu)差對(dui)承載能力影(ying)響較(jiao)大(da)(da)﹐故圓弧(hu)(hu)齒輪(lun)對(dui)制造和安裝精度要(yao)求(qiu)較(jiao)高(gao)(gao)。此外﹐單圓弧(hu)(hu)齒輪(lun)輪(lun)齒彎曲(qu)強(qiang)度較(jiao)弱﹔切削同一模數的(de)大(da)(da)﹑小齒輪(lun)﹐需用兩把不同的(de)滾(gun)刀。
