振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)(shai)分設(she)(she)(she)備是在(zai)(zai)振(zhen)動(dong)(dong)(dong)(dong)器(qi)的(de)(de)驅(qu)動(dong)(dong)(dong)(dong)下篩(shai)(shai)(shai)箱(xiang)作連續運動(dong)(dong)(dong)(dong)、將位于篩(shai)(shai)(shai)面(mian)上的(de)(de)物料(liao)連續的(de)(de)被拋射和(he)下落，是小于篩(shai)(shai)(shai)孔的(de)(de)顆粒經過篩(shai)(shai)(shai)面(mian)，從(cong)而(er)(er)完成篩(shai)(shai)(shai)分分機的(de)(de)作業的(de)(de)目的(de)(de)。普通振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)(shai)分機振(zhen)動(dong)(dong)(dong)(dong)頻率為10~20HZ，高(gao)(gao)頻振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)(shai)為25~50HZ，設(she)(she)(she)備在(zai)(zai)這樣高(gao)(gao)頻的(de)(de)振(zhen)動(dong)(dong)(dong)(dong)狀態下工(gong)作，如果(guo)采用(yong)(yong)普通的(de)(de)非防松型螺(luo)栓、螺(luo)母停止銜接固定，很容易脫帽、松動(dong)(dong)(dong)(dong)導致篩(shai)(shai)(shai)箱(xiang)出位和(he)變形，并且零部件(jian)中應(ying)力(li)升高(gao)(gao)傳動(dong)(dong)(dong)(dong)失敗(bai)，從(cong)而(er)(er)使(shi)振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)(shai)分設(she)(she)(she)備不能正(zheng)常工(gong)作，嚴重的(de)(de)可形成振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)(shai)的(de)(de)零部件(jian)損壞、人(ren)員(yuan)平安(an)得不到保證。所以振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)(shai)的(de)(de)螺(luo)栓銜接固定工(gong)藝中，除了采用(yong)(yong)普通的(de)(de)螺(luo)母外還必需(xu)運用(yong)(yong)一(yi)些防松型螺(luo)母進一(yi)步加固，保證振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)(shai)分設(she)(she)(she)備可以平安(an)牢靠的(de)(de)正(zheng)常運作。
