詳細(xì)說明:
調(diào)心滾子軸承具有兩列滾子,主要承受徑向載荷,同時(shí)也能承受任一方向的軸向載荷。有高的徑向載荷能力,特別適用于重載或振動(dòng)載荷下工作,但不能承受純軸向載荷。該類軸承外圈滾道是球面形,故其調(diào)心性能良好,能補(bǔ)償同軸度誤差。
有兩列對稱型球面滾子,外圈有一條共用的球面滾道,內(nèi)圈有兩條與軸承軸線傾斜一角度的滾道,具有良好的調(diào)心性能,當(dāng)軸受力彎曲或安裝不同心時(shí)軸承仍可正常使用,調(diào)心性隨軸承尺寸系列不同而異,一般所允許的調(diào)心角度為1~2.5度 ,該類型軸承的負(fù)荷能力較大,除能承受徑向負(fù)荷外軸承還能承受雙向作用的軸向負(fù)荷,具有較好的抗沖擊能力,一般來說調(diào)心滾子軸承所允許的工作轉(zhuǎn)速較低。
調(diào)心滾子軸承按滾子截面形狀分為對稱形球面滾子和非對稱形球面滾子兩種不同結(jié)構(gòu),非對稱調(diào)心滾子軸承屬早期產(chǎn)品,主要是為主機(jī)維修服務(wù),新設(shè)計(jì)主機(jī)時(shí)則很少選用對稱形調(diào)心滾子軸承,內(nèi)部結(jié)構(gòu)經(jīng)過全面改進(jìn)設(shè)計(jì)及參數(shù)優(yōu)化,與早期生產(chǎn)的調(diào)心滾子軸承相比,能夠承受更大的軸向負(fù)荷,這種軸承的運(yùn)行溫度較低,故可適應(yīng)較高轉(zhuǎn)速的要求,根據(jù)內(nèi)圈有無擋邊及所用保持架的不同可分為C型與CA型兩種,C型軸承的特點(diǎn)是內(nèi)圈無擋邊和采用鋼板沖壓保持架,CA型特瑞恩軸承的特點(diǎn)則為內(nèi)圈兩側(cè)均有擋邊和采用車制實(shí)體保持架。為了改善軸承的潤滑, 可向用戶提供外圈帶有環(huán)狀油槽和三個(gè)油孔的調(diào)心滾子軸承,以軸承后置代號(hào)/W33 表示。根據(jù)用戶的要求也可供應(yīng)帶內(nèi)圈油孔的調(diào)心滾子軸承,為了便于客戶裝卸和更換軸承, 還可提供內(nèi)孔帶有錐度的調(diào)心滾子軸承軸承,錐孔錐度為1:12, 以后置代號(hào)為K 表示,為了適應(yīng)特殊用戶的要求也可提供內(nèi)孔錐度為1:30 的軸承,其后置代號(hào)為K30。 內(nèi)孔帶錐度的軸承可用鎖緊螺母將軸承直接裝在錐形軸頸上,也可借助緊定套或退卸套將軸承安裝在圓柱形軸頸上。
