SCW軸裝式減速機（JB/T6387—1992）直(zhi)接套裝(zhuang)在工(gong)(gong)作機(ji)主軸(zhou)上，包括SCWU，SCWS，SCWO三個系列(lie)。主要(yao)應(ying)用(yong)于冶金、礦山、起重、運輸、化工(gong)(gong)、建筑等(deng)機(ji)械設備的(de)減速傳動(dong)。
SCW軸裝式(shi)減速機設備特(te)點：
軸裝式蝸(gua)(gua)(gua)(gua)(gua)輪(lun)蝸(gua)(gua)(gua)(gua)(gua)桿(gan)(gan)減(jian)速(su)機(ji)可以(yi)得到很大的(de)傳動(dong)(dong)(dong)(dong)(dong)比，其(qi)承載能(neng)力大大高(gao)于(yu)交錯軸斜齒輪(lun)機(ji)構蝸(gua)(gua)(gua)(gua)(gua)桿(gan)(gan)傳動(dong)(dong)(dong)(dong)(dong)相當于(yu)螺旋傳動(dong)(dong)(dong)(dong)(dong)，為多齒嚙合傳動(dong)(dong)(dong)(dong)(dong)，故(gu)傳動(dong)(dong)(dong)(dong)(dong)平穩、噪音很小(xiao)具(ju)有自鎖(suo)性(xing)。當蝸(gua)(gua)(gua)(gua)(gua)桿(gan)(gan)的(de)導程(cheng)角小(xiao)于(yu)嚙合輪(lun)齒間的(de)當量摩(mo)擦角時(shi)，機(ji)構具(ju)有自鎖(suo)性(xing)，可實現反(fan)(fan)向自鎖(suo)，即只能(neng)由蝸(gua)(gua)(gua)(gua)(gua)桿(gan)(gan)帶(dai)動(dong)(dong)(dong)(dong)(dong)蝸(gua)(gua)(gua)(gua)(gua)輪(lun)，而(er)不能(neng)由蝸(gua)(gua)(gua)(gua)(gua)輪(lun)帶(dai)動(dong)(dong)(dong)(dong)(dong)蝸(gua)(gua)(gua)(gua)(gua)桿(gan)(gan)。如在其(qi)重(zhong)機(ji)械中使(shi)(shi)用的(de)自鎖(suo)蝸(gua)(gua)(gua)(gua)(gua)桿(gan)(gan)機(ji)構，其(qi)反(fan)(fan)向自鎖(suo)性(xing)可起安全保護作用傳動(dong)(dong)(dong)(dong)(dong)效率較(jiao)低(di)，磨損較(jiao)嚴重(zhong)。蝸(gua)(gua)(gua)(gua)(gua)輪(lun)蝸(gua)(gua)(gua)(gua)(gua)桿(gan)(gan)嚙合傳動(dong)(dong)(dong)(dong)(dong)時(shi)，嚙合輪(lun)齒間的(de)相對滑動(dong)(dong)(dong)(dong)(dong)速(su)度大，故(gu)摩(mo)擦損耗大、效率低(di)。另一方面，相對滑動(dong)(dong)(dong)(dong)(dong)速(su)度大使(shi)(shi)齒面磨損嚴重(zhong)、發熱(re)嚴重(zhong)，為了散熱(re)和減(jian)小(xiao)磨損，常采用價格較(jiao)為昂(ang)貴的(de)減(jian)摩(mo)性(xing)與(yu)抗磨性(xing)較(jiao)好的(de)材料(liao)及良好的(de)潤滑裝置，因(yin)而(er)成本較(jiao)高(gao)。
SCW軸裝式(shi)減速(su)機工(gong)作條件：減速(su)器(qi)蝸(gua)桿軸轉速(su)不超過1500r/min；工(gong)作環境溫(wen)(wen)度為－40～40℃，當工(gong)作環境溫(wen)(wen)度低(di)于0℃時，啟動前潤滑油(you)必須加熱(re)到(dao)0℃以(yi)上；減速(su)器(qi)可(ke)正、反向運轉。
