國內支重輪存在的問題

國內廠家(jia)生產的(de)支重輪問題：

      市(shi)場惡性競爭，產(chan)品幾個重(zhong)(zhong)要結構發生(sheng)偷(tou)工減(jian)料 如輪體圓(yuan)(yuan)徑(jing)減(jian)小(xiao)、支軸(zhou)變細、銅(tong)(tong)(tong)套(tao)長度縮(suo)短等(deng)等(deng).輪體圓(yuan)(yuan)徑(jing)的(de)減(jian)小(xiao) 變成(cheng)(cheng)輪子線(xian)速度加(jia)快，軸(zhou)套(tao)承受(shou)的(de)摩擦(ca)越多(duo)。支軸(zhou)變細道(dao)理也是(shi)一樣，同樣承受(shou)撞擊(ji)的(de)力度也會不夠，照成(cheng)(cheng)軸(zhou)變形或者斷掉(diao)。 銅(tong)(tong)(tong)套(tao)起到摩擦(ca)作(zuo)用，銅(tong)(tong)(tong)層(ceng)必須(xu)經過滾扎后才不易脫落，吉林支重(zhong)(zhong)輪，正(zheng)常得(de)0.35mm以上銅(tong)(tong)(tong)層(ceng)才達標，減(jian)少(shao)銅(tong)(tong)(tong)套(tao)長度支重(zhong)(zhong)輪的(de)意義也就失去了作(zuo)用，減(jian)少(shao)長度等(deng)同于減(jian)少(shao)受(shou)力面(mian)積。所以解決產(chan)品這幾樣缺點，挖掘機支重(zhong)(zhong)輪廠家(jia)，國內產(chan)品相對國外(wai)產(chan)品的(de)優勢是(shi)非常大的(de)。

      支(zhi)重(zhong)輪(lun)是履(lv)帶式工程機械底盤四(si)輪(lun)一帶中的一種，  它的主要作(zuo)用是支(zhi)撐著挖掘機與推(tui)土機的重(zhong)量(liang)，讓履(lv)帶沿著輪(lun)子前進。

      支重輪的結構：輪體、支重輪軸、軸套、密封圈、端蓋等相關部件構成。支重輪可分為單邊支重輪與雙邊支重輪；挖掘機用支重輪與推土機用支重輪，挖掘機用支重輪一般是黑色油漆，推土機支重輪一般是黃色油漆。
