軸(zhou)承(cheng)(Bearing)是當代機械(xie)(xie)設備中(zhong)一種重要(yao)零(ling)部件。它的(de)主要(yao)功能是支(zhi)撐(cheng)機械(xie)(xie)旋(xuan)轉(zhuan)體,降低其(qi)運動過程中(zhong)的(de)摩擦(ca)系數,并(bing)保證其(qi)回轉(zhuan)精度。
按(an)運動(dong)元件摩(mo)擦性質的(de)不同,軸承(cheng)可分為(wei)滾動(dong)軸承(cheng)和滑動(dong)軸承(cheng)兩大類。其中滾動(dong)軸承(cheng)已經(jing)標準(zhun)化、系列化,但與滑動(dong)軸承(cheng)相比(bi)它(ta)的(de)徑向尺寸、振動(dong)和噪聲較大,價格也較高。
滾(gun)動軸(zhou)承(cheng)(cheng)(cheng)一般由外圈、內圈、滾(gun)動體和保持架四部分組成。按滾(gun)動體的形狀,滾(gun)動軸(zhou)承(cheng)(cheng)(cheng)分為(wei)球軸(zhou)承(cheng)(cheng)(cheng)和滾(gun)子軸(zhou)承(cheng)(cheng)(cheng)兩大類。
早期的直線(xian)運(yun)動軸承(cheng)(cheng)形式,就是在一(yi)(yi)排撬(qiao)板下放置一(yi)(yi)排木桿。現代(dai)直線(xian)運(yun)動軸承(cheng)(cheng)使用的是同(tong)一(yi)(yi)種工作原理,只不過有時用球代(dai)替滾(gun)(gun)子(zi)。最簡單(dan)的旋轉軸承(cheng)(cheng)是軸套軸承(cheng)(cheng),它只是一(yi)(yi)個夾(jia)在車(che)輪(lun)和輪(lun)軸之(zhi)間的襯(chen)(chen)套。這種設計隨后(hou)被滾(gun)(gun)動軸承(cheng)(cheng)替代(dai),就是用很多圓柱形的滾(gun)(gun)子(zi)替代(dai)原先的襯(chen)(chen)套,每個滾(gun)(gun)動體就像一(yi)(yi)個單(dan)獨的車(che)輪(lun)。
滾(gun)動軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)按其(qi)所能(neng)承(cheng)(cheng)(cheng)(cheng)(cheng)受的(de)(de)(de)載(zai)荷(he)方向(xiang)或(huo)公(gong)(gong)(gong)稱接(jie)觸(chu)(chu)角(jiao)的(de)(de)(de)不同分(fen)為(wei)(wei)向(xiang)心(xin)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)和推力軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)。其(qi)中徑向(xiang)接(jie)觸(chu)(chu)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)為(wei)(wei)公(gong)(gong)(gong)稱接(jie)觸(chu)(chu)角(jiao)為(wei)(wei)0的(de)(de)(de)向(xiang)心(xin)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng),向(xiang)心(xin)角(jiao)接(jie)觸(chu)(chu)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)為(wei)(wei)公(gong)(gong)(gong)稱接(jie)觸(chu)(chu)角(jiao)大于(yu)0到45的(de)(de)(de)向(xiang)心(xin)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)。軸(zhou)向(xiang)接(jie)觸(chu)(chu)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)為(wei)(wei)公(gong)(gong)(gong)稱接(jie)觸(chu)(chu)角(jiao)為(wei)(wei)90的(de)(de)(de)推力軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng),推力角(jiao)接(jie)觸(chu)(chu)軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)為(wei)(wei)公(gong)(gong)(gong)稱接(jie)觸(chu)(chu)角(jiao)大于(yu)45但小(xiao)于(yu)90的(de)(de)(de)推力軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)。
按(an)(an)滾(gun)動體的形狀可(ke)分為球(qiu)軸(zhou)承(cheng)(cheng)和滾(gun)子(zi)(zi)(zi)軸(zhou)承(cheng)(cheng)。滾(gun)子(zi)(zi)(zi)軸(zhou)承(cheng)(cheng)按(an)(an)滾(gun)子(zi)(zi)(zi)種類分為:圓柱滾(gun)子(zi)(zi)(zi)軸(zhou)承(cheng)(cheng)、滾(gun)針軸(zhou)承(cheng)(cheng)、圓錐滾(gun)子(zi)(zi)(zi)軸(zhou)承(cheng)(cheng)和調心滾(gun)子(zi)(zi)(zi)軸(zhou)承(cheng)(cheng)。
按(an)其工作時能否調(diao)心(xin)分為調(diao)心(xin)軸承(cheng)----滾道是球面形的,能適應兩滾道軸心(xin)線(xian)間(jian)(jian)的角偏差(cha)及角運動的軸承(cheng)和非調(diao)心(xin)軸承(cheng)(剛(gang)性軸承(cheng))----能阻抗滾道間(jian)(jian)軸心(xin)線(xian)角偏移的軸承(cheng)。
按滾動體的(de)列數分為(wei)單列軸(zhou)承(cheng)(cheng)、雙列軸(zhou)承(cheng)(cheng)和多(duo)列軸(zhou)承(cheng)(cheng)。
按其部(bu)件(套圈)能否分離(li)分為可分離(li)軸(zhou)承(cheng)和不可分離(li)軸(zhou)承(cheng)。
按其結構(gou)形狀(如有(you)無裝(zhuang)填槽,有(you)無內、外圈(quan)以及套圈(quan)的形狀,擋邊(bian)的結構(gou),甚至有(you)無保(bao)持(chi)架等)還(huan)可以分為多種(zhong)結構(gou)類(lei)型。
按其外徑尺寸大小分為微型軸(zhou)承(cheng)(<26mm)、小型軸(zhou)承(cheng)(28-55mm)、中(zhong)小型軸(zhou)承(cheng)(60-115)、中(zhong)大型軸(zhou)承(cheng)(120-190mm)、大型軸(zhou)承(cheng)(200-430mm)和特大型軸(zhou)承(cheng)(>440mm)。
按應(ying)用領域分為(wei)電機軸(zhou)(zhou)承(cheng)(cheng)、軋(ya)機軸(zhou)(zhou)承(cheng)(cheng)、主軸(zhou)(zhou)承(cheng)(cheng)等。
按材料分為陶瓷軸承、塑料軸承等。
