推力球軸承(cheng)采用高速運(yùn)轉時可承受(shòu)推力載荷的(de)設計,由帶🔴有(you)球滾動的滾(gǔn)道溝的墊圈(quān)狀套圈構成(chéng)。由于套圈為(wei)座墊形,因此(cǐ)🔱,推力球軸承(chéng)被分為平底(dǐ)座墊型和調(diao)心🙇🏻球面座墊(nian)型兩種類型(xíng)。另外,這種軸(zhóu)承可承受軸(zhou)向載荷,但不(bú)能承受徑向(xiang)載荷。該類軸(zhóu)🈲承隻适用于(yu)承受一面軸(zhou)向負荷、轉速(sù)🐉較低的機件(jian)🔞上,例如起重(zhong)機吊鈎、立式(shì)水泵立式離(lí)心機、千斤頂(ding)、低速減速器(qì)等。軸承的軸(zhou)圈、座圈和滾(gun)動體是分離(lí)的,可以分别(bie)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.
