軸承(Bearing)是當代機(ji)械(xie)設(she)備中一種(zhong)重要(yao)零(ling)部(bu)件。它的主要(yao)功能是支撐(cheng)機(ji)械(xie)旋轉(zhuan)體,降低其(qi)(qi)運動過程中的摩擦系數,并保證其(qi)(qi)回(hui)轉(zhuan)精度(du)。
按運(yun)動(dong)(dong)元(yuan)件摩擦性質的不同(tong),軸(zhou)承(cheng)可(ke)分為(wei)滾(gun)動(dong)(dong)軸(zhou)承(cheng)和(he)滑(hua)動(dong)(dong)軸(zhou)承(cheng)兩大類(lei)。其(qi)中滾(gun)動(dong)(dong)軸(zhou)承(cheng)已經標準化、系列化,但與滑(hua)動(dong)(dong)軸(zhou)承(cheng)相比它(ta)的徑向尺(chi)寸(cun)、振動(dong)(dong)和(he)噪聲(sheng)較大,價格也較高。
滾(gun)動軸(zhou)承(cheng)(cheng)一般由外圈(quan)、內圈(quan)、滾(gun)動體和(he)保持架(jia)四部(bu)分(fen)組成。按滾(gun)動體的形(xing)狀,滾(gun)動軸(zhou)承(cheng)(cheng)分(fen)為球軸(zhou)承(cheng)(cheng)和(he)滾(gun)子軸(zhou)承(cheng)(cheng)兩大類。
早期的(de)(de)直線(xian)運(yun)動(dong)軸承(cheng)(cheng)形式,就(jiu)是(shi)在一(yi)排撬板下放置一(yi)排木桿。現代直線(xian)運(yun)動(dong)軸承(cheng)(cheng)使用(yong)(yong)的(de)(de)是(shi)同(tong)一(yi)種(zhong)工作原理,只(zhi)不過有時用(yong)(yong)球代替(ti)滾子(zi)。最(zui)簡(jian)單的(de)(de)旋轉軸承(cheng)(cheng)是(shi)軸套軸承(cheng)(cheng),它(ta)只(zhi)是(shi)一(yi)個夾在車(che)輪(lun)和輪(lun)軸之(zhi)間的(de)(de)襯(chen)套。這種(zhong)設計(ji)隨后被(bei)滾動(dong)軸承(cheng)(cheng)替(ti)代,就(jiu)是(shi)用(yong)(yong)很多圓柱形的(de)(de)滾子(zi)替(ti)代原先的(de)(de)襯(chen)套,每個滾動(dong)體就(jiu)像一(yi)個單獨(du)的(de)(de)車(che)輪(lun)。
滾動軸(zhou)承(cheng)(cheng)(cheng)按(an)其(qi)所能承(cheng)(cheng)(cheng)受的(de)(de)載荷(he)方向(xiang)(xiang)或公(gong)稱(cheng)接觸(chu)(chu)角(jiao)(jiao)(jiao)(jiao)的(de)(de)不同分為(wei)(wei)向(xiang)(xiang)心軸(zhou)承(cheng)(cheng)(cheng)和(he)推力軸(zhou)承(cheng)(cheng)(cheng)。其(qi)中徑向(xiang)(xiang)接觸(chu)(chu)軸(zhou)承(cheng)(cheng)(cheng)為(wei)(wei)公(gong)稱(cheng)接觸(chu)(chu)角(jiao)(jiao)(jiao)(jiao)為(wei)(wei)0的(de)(de)向(xiang)(xiang)心軸(zhou)承(cheng)(cheng)(cheng),向(xiang)(xiang)心角(jiao)(jiao)(jiao)(jiao)接觸(chu)(chu)軸(zhou)承(cheng)(cheng)(cheng)為(wei)(wei)公(gong)稱(cheng)接觸(chu)(chu)角(jiao)(jiao)(jiao)(jiao)大于0到(dao)45的(de)(de)向(xiang)(xiang)心軸(zhou)承(cheng)(cheng)(cheng)。軸(zhou)向(xiang)(xiang)接觸(chu)(chu)軸(zhou)承(cheng)(cheng)(cheng)為(wei)(wei)公(gong)稱(cheng)接觸(chu)(chu)角(jiao)(jiao)(jiao)(jiao)為(wei)(wei)90的(de)(de)推力軸(zhou)承(cheng)(cheng)(cheng),推力角(jiao)(jiao)(jiao)(jiao)接觸(chu)(chu)軸(zhou)承(cheng)(cheng)(cheng)為(wei)(wei)公(gong)稱(cheng)接觸(chu)(chu)角(jiao)(jiao)(jiao)(jiao)大于45但小于90的(de)(de)推力軸(zhou)承(cheng)(cheng)(cheng)。
按(an)滾(gun)(gun)動體(ti)的(de)形(xing)狀可分為球軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)和滾(gun)(gun)子(zi)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)。滾(gun)(gun)子(zi)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)按(an)滾(gun)(gun)子(zi)種(zhong)類分為:圓柱滾(gun)(gun)子(zi)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)、滾(gun)(gun)針軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)、圓錐滾(gun)(gun)子(zi)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)和調心滾(gun)(gun)子(zi)軸(zhou)(zhou)(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)。
按其工作時能(neng)否調(diao)心分為調(diao)心軸(zhou)(zhou)承(cheng)(cheng)(cheng)----滾道(dao)是(shi)球面形的(de),能(neng)適(shi)應兩滾道(dao)軸(zhou)(zhou)心線間的(de)角(jiao)偏差(cha)及角(jiao)運動(dong)的(de)軸(zhou)(zhou)承(cheng)(cheng)(cheng)和非調(diao)心軸(zhou)(zhou)承(cheng)(cheng)(cheng)(剛性軸(zhou)(zhou)承(cheng)(cheng)(cheng))----能(neng)阻(zu)抗(kang)滾道(dao)間軸(zhou)(zhou)心線角(jiao)偏移的(de)軸(zhou)(zhou)承(cheng)(cheng)(cheng)。
按滾動體的列(lie)(lie)數分(fen)為單列(lie)(lie)軸承(cheng)、雙(shuang)列(lie)(lie)軸承(cheng)和多列(lie)(lie)軸承(cheng)。
