推力球(qiú)軸承采用高速運轉時可承受推力載荷的設計,由(yóu)帶有球滾動的滾道溝的墊圈狀套圈構(gòu)成。由于套圈為座墊形,因此,推(tuī)力球軸承被分為平底座墊型和調(diào)心球面座(zuò)墊型兩種類型(xíng)。另外,這種(zhǒng)軸承可承(chéng)受軸向載荷,但不能(néng)承受(shòu)徑向載荷。該類軸承隻适用于承受(shòu)一面軸向(xiàng)負荷、轉速較低的機件(jiàn)上(shàng),例如起重機吊鈎、立式水泵立式離心機、千斤頂、低(dī)速減速器等。軸承的軸圈、座圈和滾動體是分離的(de),可以(yǐ)分别裝拆。

Thrust ball bearings are designed to withstand thrust loads at high speeds, consisting of gasket rings with ball rolling raceway grooves. Because the ring is cushion, therefore, thrust ball bearing is divided into two types: flat bottom cushion type and center adjusting spherical cushion type. Besides, the bearing can bear axial load, but it can't bear radial load. This kind of bearing is only suitable for the parts with one axial load and low speed, such as crane hoisting hook, vertical pump vertical centrifuge, Jack, low speed reducer and so on. Bearing rings, seat rings and rolling bodies are separated, and they can be assembled and disassembled separately.
