滾動(dòng)軸承的分類
1.按滾動(dòng)軸承結(jié)構(gòu)類型分類
(1)軸承按其所能承受的載荷方向或公稱接觸角的不同,分為:
1)向心軸承----主要用于承受徑向載荷的滾動(dòng)軸承,其公稱接觸角從0到45。按公稱接觸角不同,又分為:徑向接觸軸承----公稱接觸角為0的向心軸承:向心角接觸軸承----公稱接觸角大于0到45的向心軸承。
2)推力軸承----主要用于承受軸向載荷的滾動(dòng)軸承,其公稱接觸角大于45到90。按公稱接觸角不同又分為:軸向接觸軸承----公稱接觸角為90的推力軸承:推力角接觸軸承----公稱接觸角大于45但小于90的推力軸承。
(2)軸承按其滾動(dòng)體的種類,分為:
1)球軸承----滾動(dòng)體為球:
2)滾子軸承----滾動(dòng)體為滾子。滾子軸承按滾子種類,又分為:圓柱滾子軸承----滾動(dòng)體是圓柱滾子的軸承,圓柱滾子的長(zhǎng)度與直徑之比小于或等于3;滾針軸承----滾動(dòng)體是滾針的軸承,滾針的長(zhǎng)度與直徑之比大于3,但直徑小于或等于5mm;圓錐滾子軸承----滾動(dòng)體是圓錐滾子的軸承;調(diào)心滾子軸承一一滾動(dòng)體是球面滾子的軸承。
(3)軸承按其工作時(shí)能否調(diào)心,分為:
1)調(diào)心軸承----滾道是球面形的,能適應(yīng)兩滾道軸心線間的角偏差及角運(yùn)動(dòng)的軸承;
2)非調(diào)心軸承(剛性軸承)----能阻抗?jié)L道間軸心線角偏移的軸承。
(4)軸承按滾動(dòng)體的列數(shù),分為:
1)單列軸承----具有一列滾動(dòng)體的軸承;
2)雙列軸承----具有兩列滾動(dòng)體的軸承;
3)多列軸承----具有多于兩列滾動(dòng)體的軸承,如三列、四列軸承。
(5)軸承按其部件能否分離,分為:
1)可分離軸承----具有可分離部件的軸承;
2)不可分離軸承----軸承在最終配套后,套圈均不能任意自由分離的軸承。
(6)軸承按其結(jié)構(gòu)形狀(如有無裝填槽,有無內(nèi)、外圈以及套圈的形狀,擋邊的結(jié)構(gòu),甚至有無保持架等)還可以分為多種結(jié)構(gòu)類型。
2.按滾動(dòng)軸承尺寸大小分類軸承按其外徑尺寸大小,分為:
(1)微型軸承----公稱外徑尺寸范圍為26mm以下的軸承;
(2)小型軸承----公稱外徑尺寸范圍為28-55mm的軸承;
(3)中小型軸承----公稱外徑尺寸范圍為60-115mm的軸承;
(4)中大型軸承----公稱外徑尺寸范圍為120-190mm的軸承
(5)大型軸承----公稱外徑尺寸范圍為200-430mm的軸承;
(6)特大型軸承----公稱外徑尺寸范圍為440mm以上的軸承。
滾動(dòng)軸承的基本生產(chǎn)過程
由于滾動(dòng)軸承的類型、結(jié)構(gòu)型式、公差等級(jí)、技術(shù)要求、材料及批量等的不同,其基本生產(chǎn)過程也不完全相同。
一、各種軸承主要零件的加工過程:
