軸承(Bearing)是當代機械設備中一種重要(yao)零(ling)部件。它的主要(yao)功(gong)能是支撐機械旋轉體,降低其運動過程(cheng)中的摩(mo)擦系數,并保(bao)證其回轉精度。
按運動(dong)(dong)元件摩擦性(xing)質的(de)不同,軸(zhou)(zhou)承(cheng)可分為(wei)滾動(dong)(dong)軸(zhou)(zhou)承(cheng)和滑(hua)動(dong)(dong)軸(zhou)(zhou)承(cheng)兩大(da)(da)類。其中滾動(dong)(dong)軸(zhou)(zhou)承(cheng)已(yi)經(jing)標準(zhun)化、系列化,但(dan)與(yu)滑(hua)動(dong)(dong)軸(zhou)(zhou)承(cheng)相比它(ta)的(de)徑向尺寸、振(zhen)動(dong)(dong)和噪(zao)聲較大(da)(da),價格也較高。
滾動(dong)軸(zhou)承(cheng)一般(ban)由外圈、內(nei)圈、滾動(dong)體和保持架四部分組成。按滾動(dong)體的形狀(zhuang),滾動(dong)軸(zhou)承(cheng)分為球軸(zhou)承(cheng)和滾子軸(zhou)承(cheng)兩大類。
早期的直線運(yun)動(dong)軸(zhou)(zhou)承(cheng)形式(shi),就(jiu)是(shi)在一(yi)排撬板下(xia)放置一(yi)排木桿(gan)。現代(dai)直線運(yun)動(dong)軸(zhou)(zhou)承(cheng)使用(yong)(yong)的是(shi)同一(yi)種(zhong)工作原理(li),只不(bu)過有時用(yong)(yong)球代(dai)替(ti)滾(gun)子(zi)。最(zui)簡單(dan)的旋轉(zhuan)軸(zhou)(zhou)承(cheng)是(shi)軸(zhou)(zhou)套軸(zhou)(zhou)承(cheng),它只是(shi)一(yi)個夾在車輪和輪軸(zhou)(zhou)之間的襯套。這種(zhong)設計隨(sui)后被滾(gun)動(dong)軸(zhou)(zhou)承(cheng)替(ti)代(dai),就(jiu)是(shi)用(yong)(yong)很多圓柱形的滾(gun)子(zi)替(ti)代(dai)原先的襯套,每個滾(gun)動(dong)體就(jiu)像一(yi)個單(dan)獨的車輪。
調心滾子軸承有(you)兩列(lie)(lie)對(dui)稱型(xing)球面(mian)滾(gun)子,主要承(cheng)(cheng)(cheng)受徑向(xiang)載荷(he),同(tong)(tong)(tong)時(shi)也能(neng)(neng)(neng)(neng)承(cheng)(cheng)(cheng)受任一(yi)方向(xiang)的(de)(de)(de)軸(zhou)(zhou)向(xiang)載荷(he),但不能(neng)(neng)(neng)(neng)承(cheng)(cheng)(cheng)受純軸(zhou)(zhou)向(xiang)載荷(he)。該(gai)類軸(zhou)(zhou)承(cheng)(cheng)(cheng)外圈滾(gun)道是球面(mian)形(xing),故其調(diao)(diao)心(xin)性能(neng)(neng)(neng)(neng)良(liang)好(hao),能(neng)(neng)(neng)(neng)補償(chang)同(tong)(tong)(tong)軸(zhou)(zhou)度(du)誤差,當軸(zhou)(zhou)受力彎(wan)曲或安裝不同(tong)(tong)(tong)心(xin)時(shi)軸(zhou)(zhou)承(cheng)(cheng)(cheng)仍可正常使用(yong)(yong),調(diao)(diao)心(xin)性隨軸(zhou)(zhou)承(cheng)(cheng)(cheng)尺寸系(xi)列(lie)(lie)不同(tong)(tong)(tong)而異(yi),一(yi)般所允(yun)許的(de)(de)(de)調(diao)(diao)心(xin)角度(du)為1~2.5度(du) ,該(gai)類型(xing)軸(zhou)(zhou)承(cheng)(cheng)(cheng)的(de)(de)(de)負荷(he)能(neng)(neng)(neng)(neng)力較(jiao)大,除能(neng)(neng)(neng)(neng)承(cheng)(cheng)(cheng)受徑向(xiang)負荷(he)外軸(zhou)(zhou)承(cheng)(cheng)(cheng)還能(neng)(neng)(neng)(neng)承(cheng)(cheng)(cheng)受雙向(xiang)作(zuo)用(yong)(yong)的(de)(de)(de)軸(zhou)(zhou)向(xiang)負荷(he),具有(you)較(jiao)好(hao)的(de)(de)(de)抗沖擊能(neng)(neng)(neng)(neng)力,一(yi)般來(lai)說調(diao)(diao)心(xin)滾(gun)子軸(zhou)(zhou)承(cheng)(cheng)(cheng)所允(yun)許的(de)(de)(de)工作(zuo)轉速較(jiao)低。適用(yong)(yong)于重載或振動載荷(he)下工作(zuo)。
