雙列調(diào)心滾子軸承是種能承受重大負(fù)荷的軸承。這種軸承有兩列滾子,外圈有條共用的球面滾道,內(nèi)圈有兩條相對(duì)軸承軸心線傾斜成定角度的滾道,軸承可以自動(dòng)調(diào)心。這樣就可以補(bǔ)償在軸彎曲變形與軸承安裝部位形成的同心偏差。該類軸承除能承受徑向負(fù)荷外,還能承受雙向作用的軸向負(fù)荷,具有較好的抗沖擊力。般來(lái)說(shuō)調(diào)心滾子軸承所允許的工作轉(zhuǎn)速。
雙列調(diào)心滾子軸承按滾子截面形狀分為對(duì)稱形球面滾子和非對(duì)稱形球面滾子兩種不同結(jié)構(gòu)。非對(duì)稱調(diào)心滾子軸承屬早期產(chǎn)品,對(duì)稱形調(diào)心滾子軸承內(nèi)部結(jié)構(gòu)經(jīng)過(guò)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,顧可適應(yīng)較高轉(zhuǎn)速的要求。根據(jù)內(nèi)圈有無(wú)擋邊及所用保持器的不同,可分 C 型與 CA 型兩種,CA 型軸承的點(diǎn)為內(nèi)圈兩側(cè)均有擋邊和采用車制保持器。
為了改善雙列調(diào)心滾子軸承的潤(rùn)滑,可向客戶提供外圈帶有環(huán)形油槽和三個(gè)油孔的調(diào)心滾子軸承,以軸承后置代號(hào)/W33表示
為了便于客戶裝卸和更換軸承,LMC 還提供內(nèi)孔帶有錐度的調(diào)心滾子軸承,軸承錐孔錐度般為 1:20,以后置代號(hào)K表示,為適應(yīng)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,也可借助緊定套將軸承安裝在圓柱形軸頸上。
