機器底腳墊鐵為什么都不超過三塊?
答:機(ji)(ji)器(qi)底腳墊(dian)(dian)(dian)(dian)鐵(tie)不應超(chao)過三塊，是(shi)因為這三塊墊(dian)(dian)(dian)(dian)鐵(tie)可以把機(ji)(ji)床墊(dian)(dian)(dian)(dian)得很平,而(er)且便于調(diao)整(zheng)。調(diao)整(zheng)時(shi),只(zhi)要移(yi)動中間(jian)的(de)(de)墊(dian)(dian)(dian)(dian)鐵(tie) 可以了。在高低相(xiang)差(cha)太大時(shi),可以用厚薄不同的(de)(de)墊(dian)(dian)(dian)(dian)鐵(tie)3做較大的(de)(de)調(diao)整(zheng),這樣機(ji)(ji)器(qi) 會平穩。如果只(zhi)用一(yi)塊斜墊(dian)(dian)(dian)(dian)鐵(tie))機(ji)(ji)器(qi)與(yu)墊(dian)(dian)(dian)(dian)鐵(tie)的(de)(de)接觸只(zhi)有一(yi)條線,在這個地方墊(dian)(dian)(dian)(dian)鐵(tie)承受(shou)的(de)(de)力量(liang)很大,容(rong)(rong)易(yi)變形,因而(er)容(rong)(rong)易(yi)失掉(diao)安裝(zhuang)的(de)(de)度。
