不(bu)銹(xiu)鋼(gang)齒條(tiao)知識(shi)：不(bu)銹(xiu)鋼(gang)齒條(tiao)的(de)(de)維(wei)護(hu)(hu)不(bu)銹(xiu)鋼(gang)齒條(tiao)得到了廣泛的(de)(de)應(ying)用(yong)。不(bu)銹(xiu)鋼(gang)齒條(tiao)不(bu)易生(sheng)銹(xiu)并不(bu)意味(wei)著它(ta)不(bu)會變臟和磨損(sun)。因(yin)此，在不(bu)銹(xiu)鋼(gang)齒條(tiao)的(de)(de)日常使(shi)(shi)(shi)用(yong)中(zhong)，要(yao)注意保養。首先(xian)，從安(an)裝的(de)(de)角度開始。齒條(tiao)的(de)(de)松緊(jin)(jin)度是重要(yao)的(de)(de)，不(bu)要(yao)太緊(jin)(jin)或太松，這樣會損(sun)壞鏈(lian)條(tiao)。不(bu)銹(xiu)鋼(gang)齒條(tiao)應(ying)保持清潔(jie)，避免(mian)陽光和雨水浸泡，防(fang)止與酸堿有機溶劑等物(wu)質(zhi)接觸。這將減少鏈(lian)傳動部件的(de)(de)腐(fu)蝕。齒條(tiao)磨損(sun)嚴重時，應(ying)更換新鏈(lian)條(tiao)等零件，以保證(zheng)良好的(de)(de)效果。新舊產品不(bu)能一(yi)起使(shi)(shi)(shi)用(yong)。這會加劇(ju)磨損(sun)。齒條(tiao)應(ying)及(ji)時加潤滑油，使(shi)(shi)(shi)鏈(lian)條(tiao)工作更加順暢快捷，減少磨損(sun)。這也是日常維(wei)護(hu)(hu)的(de)(de)問題
