蝸輪蝸杆的旋向關係

       蝸輪蝸杆齧合時旋向必須相同，隻有旋向相同才能齧合接觸。蝸輪和蝸杆的旋向由蝸杆的螺旋線方向決定，螺旋線方向相同的蝸輪
、蝸wo杆gan組zu合he
，蝸wo輪lun轉zhuan向xiang與yu蝸wo杆gan轉zhuan向xiang關guan係xi都dou是shi一yi樣yang的de，如ru蝸wo杆gan正zheng轉zhuan時shi蝸wo輪lun反fan轉zhuan，蝸wo杆gan反fan轉zhuan時shi蝸wo輪lun則ze正zheng轉zhuan，如ru果guo需xu要yao蝸wo杆gan正zheng轉zhuan時shi蝸wo輪lun轉zhuan向xiang為wei正zheng轉zhuan
，則ze必bi須xu改gai變bian蝸wo杆gan螺luo旋xuan線xian方fang向xiang。可ke以yi通tong過guo將jiang螺luo紋wen置zhi於yu圓yuan柱zhu體ti側ce麵mian位wei置zhi觀guan察cha，右you旋xuan就jiu是shi右you側ce高gao於yu左zuo側ce而er生sheng長chang向xiang上shang，左zuo旋xuan就jiu是shi左zuo側ce高gao於yu右you側ce而er生sheng長chang向xiang上shang。
