推(tui)力球軸(zhou)承采用(yòng)高速運(yun)轉時可(kě)承受推(tuī)力載荷(he)的設計(ji),由帶有(yǒu)🈲球滾動(dong)的滾道(dao)溝的墊(niàn)圈狀套(tao)圈構成(cheng)。由于套(tào)圈為座(zuò)墊形👌,因(yīn)此,推力(lì)球軸承(chéng)被分為(wéi)平底座(zuo)墊型和(hé)調心球(qiú)面座墊(niàn)型兩種(zhong)類型🐪。另(ling)外,這種(zhong)軸承可(kě)承受軸(zhou)向載荷(hé)📞,但不能(néng)承受徑(jìng)向載荷(hé)。該類軸(zhóu)♋承隻适(shi)用于承(cheng)受一面(mian)軸向負(fù)荷、轉速(su)較低的(de)機件上(shàng),例如起(qi)重機吊(diao)鈎、立式(shi)水泵立(li)式離心(xin)機、千斤(jin)頂❄️、低速(sù)減速🌐器(qì)等。軸承(chéng)的軸圈(quan)、座圈和(hé)滾動體(tǐ)是分離(li)的🐪,可以(yi)分别裝(zhuang)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.
