蝸(gua)(gua)(gua)輪蝸(gua)(gua)(gua)桿減(jian)(jian)(jian)速機(ji)有效降低故(gu)障率(lv)的(de)途徑。蝸(gua)(gua)(gua)輪蝸(gua)(gua)(gua)桿減(jian)(jian)(jian)速機(ji)在(zai)使用以(yi)前注(zhu)意以(yi)下幾(ji)點，可(ke)以(yi)有效地降低故(gu)障率(lv)。蝸(gua)(gua)(gua)輪蝸(gua)(gua)(gua)桿減(jian)(jian)(jian)速機(ji)必須正(zheng)確(que)安(an)裝(zhuang)才能(neng)確(que)保設備的(de)正(zheng)常(chang)運轉：是要(yao)為負載選擇合適的(de)RV減(jian)(jian)(jian)速機(ji)，理論上，用戶所需(xu)的(de)大(da)工作扭(niu)(niu)矩要(yao)小于蝸(gua)(gua)(gua)輪蝸(gua)(gua)(gua)桿減(jian)(jian)(jian)速機(ji)額定輸(shu)出扭(niu)(niu)矩的(de)兩倍；二是要(yao)選擇合適的(de)電(dian)動機(ji)，電(dian)動機(ji)的(de)輸(shu)出扭(niu)(niu)矩乘以(yi)RV減(jian)(jian)(jian)速機(ji)的(de)傳(chuan)動比，原則上要(yao)小于電(dian)動機(ji)的(de)額定輸(shu)出扭(niu)(niu)矩。這些都(dou)是為了避免安(an)裝(zhuang)不到(dao)位，或者負荷出現故(gu)障而停(ting)轉等情(qing)況出現時，保護蝸(gua)(gua)(gua)輪蝸(gua)(gua)(gua)桿減(jian)(jian)(jian)速機(ji)的(de)軸承(cheng)不被(bei)扭(niu)(niu)斷。
