萬向聯軸器出現裂紋或斷裂改進措施

萬向聯軸器出現裂(lie)紋或斷裂(lie)改進措施(shi)：

（1）工(gong)作(zuo)原因；鑄造橋式(shi)起重機(ji)萬向(xiang)聯(lian)軸(zhou)器出現(xian)故(gu)障主要出現(xian)在大車(che)(che)軌(gui)道(dao)端口較多、踏面(mian)磨損高低(di)不平，且(qie)軌(gui)距發(fa)生變(bian)化的(de)允許(xu)環境(jing)中，導致起重機(ji)在允許(xu)過程中車(che)(che)輪(lun)所受沖擊較大，間(jian)接作(zuo)用(yong)(yong)于萬向(xiang)聯(lian)軸(zhou)器上(shang)，縮短了使(shi)用(yong)(yong)壽命，可以對起重機(ji)大車(che)(che)軌(gui)道(dao)的(de)軌(gui)距、水平度、高低(di)差(cha)等進(jin)行調整，并(bing)對軌(gui)道(dao)端口處進(jin)行鋁熱焊接，以此來改(gai)善工(gong)作(zuo)環境(jing)。

（2）承載(zai)不(bu)均勻(yun)；鑄造橋式(shi)起重機(ji)大車車輪為(wei)分部驅動(dong)(dong)(dong)(dong)，每套大車機(ji)構(gou)都(dou)有**的制(zhi)(zhi)動(dong)(dong)(dong)(dong)系統(tong)，若4套制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)制(zhi)(zhi)動(dong)(dong)(dong)(dong)力矩(ju)(ju)(ju)調整不(bu)一致。會使(shi)制(zhi)(zhi)動(dong)(dong)(dong)(dong)過程中(zhong)4套制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)工作(zuo)不(bu)同(tong)步。很可(ke)能出現1套制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)制(zhi)(zhi)動(dong)(dong)(dong)(dong)力矩(ju)(ju)(ju)多大，造成單個萬(wan)向聯軸器(qi)所承受(shou)(shou)的沖擊載(zai)荷較大極(ji)易斷裂(lie)。可(ke)以調整制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)制(zhi)(zhi)動(dong)(dong)(dong)(dong)力矩(ju)(ju)(ju)，使(shi)4套制(zhi)(zhi)動(dong)(dong)(dong)(dong)器(qi)同(tong)步制(zhi)(zhi)動(dong)(dong)(dong)(dong)，避免單個萬(wan)向聯軸器(qi)承受(shou)(shou)扭矩(ju)(ju)(ju)過大。

（3）加工(gong)工(gong)藝(yi)；萬萬向聯軸(zhou)(zhou)器制作(zuo)時材料選用(yong)標準低、熱(re)處理工(gong)藝(yi)不當、叉頭存在(zai)(zai)鑄造缺陷以及焊接質(zhi)量(liang)等原(yuan)因，均會導致萬向聯軸(zhou)(zhou)器在(zai)(zai)使(shi)用(yong)過(guo)程(cheng)中容(rong)易形成薄弱點。可以通過(guo)選用(yong)性價比較高的(de)萬向聯軸(zhou)(zhou)器，從材料、設計、工(gong)藝(yi)上確保(bao)質(zhi)量(liang)關(guan)，在(zai)(zai)源頭上減少因質(zhi)量(liang)問題導致的(de)設備故障。

（4）型號選擇；如果(guo)萬萬向聯(lian)軸器扭矩達不到(dao)使用的要求，極易(yi)出現裂紋甚至(zhi)斷裂。
