等截面薄壁深溝球軸承基本型由外圈,內(nèi)圈,鋼球,保持架構(gòu)成,其主要承受徑向載荷,極限轉(zhuǎn)速高,等截面薄壁深溝球軸承型號(hào)分為KAA,KA,KB,KC,KD,KF,KG.詳解深溝球等截面薄壁軸承各型號(hào)尺寸剖面結(jié)構(gòu)圖

詳細(xì)介紹

等截面薄壁深溝球軸承是滾動(dòng)軸承中較為常用的一種類型，等截面薄壁深溝球軸承由一個(gè)外圈，一個(gè)內(nèi)圈、一組鋼球和一組保持架構(gòu)成。

等截面薄壁深溝球軸承主要承受徑向載荷，當(dāng)其僅承受徑向載荷時(shí)，接觸角為零。當(dāng)?shù)冉孛姹”谏顪锨蜉S承具有較大的徑向游隙時(shí)，具有一定的角接觸軸承的性能，也可同時(shí)承受徑向載荷和軸向載荷?？沙惺茌^大的軸向載荷，等截面薄壁深溝球軸承的摩擦系數(shù)很小，極限轉(zhuǎn)速也很高。在轉(zhuǎn)速較高又不宜采用推力球軸承時(shí)，也可用來承受純軸向載荷。與尺寸相同的其它類型軸承比較，此類軸承摩擦系數(shù)小，極限轉(zhuǎn)速高。

等截面薄壁深溝球軸承多為黃銅沖壓保持架，小型尺寸采用尼龍材質(zhì)保持架。

等截面薄壁深溝球軸承由于現(xiàn)代簡(jiǎn)單化、輕量化、緊湊化的理念已深入旋轉(zhuǎn)設(shè)備的設(shè)計(jì)之中，為滿足客戶的需求，等截面薄壁深溝球軸承減輕了整體的重量。薄壁深溝球軸承是常規(guī)設(shè)計(jì)的單列徑向球軸承。主要承受徑向載荷。其內(nèi)圈和外圈會(huì)有特殊的位移，這樣可以裝入的滾珠數(shù)量大約是滿滾子的一半。雖然深溝球軸承主要用來承受徑向載荷，但也可以承受有限的來自某一方向的單向推力載荷，一般與另一個(gè)軸承共同使用。但是，如果軸向載荷是重要因素，建議選擇角接觸球軸承會(huì)更合適。

軸承材質(zhì)大多采用高碳洛軸承鋼Gcr15和不銹鋼440C、9cr18。

等截面薄壁深溝球軸承分為以下幾種系列：

KAA類型，KA類型，KB類型，KC類型，KD類型，KF類型，KG類型

KAA類型截面尺寸Φ4.763mm，鋼球尺寸Φ2.381mm，內(nèi)孔尺寸Φ25.4mm~44.45mm。

KA類型截面尺寸Φ6.35mm，鋼球尺寸Φ3.175mm，內(nèi)孔尺寸Φ50.8mm~355.6mm。

KB類型截面尺寸Φ7.938mm，鋼球尺寸Φ3.969mm，內(nèi)孔尺寸Φ50.8mm~508mm。

KC類型截面尺寸Φ9.525mm，鋼球尺寸Φ4.762mm，內(nèi)孔尺寸Φ101.6mm~635mm。

KD類型截面尺寸Φ12.7mm，鋼球尺寸Φ6.35mm，內(nèi)孔尺寸Φ101.6mm~635mm。

KF類型截面尺寸Φ19.05mm，鋼球尺寸Φ9.525mm，內(nèi)孔尺寸Φ101.6mm~762mm。

KG類型截面尺寸Φ25.4mm，鋼球尺寸Φ12.7mm，內(nèi)孔尺寸Φ101.6mm~1016mm。
