關(guān)節軸承是一(yi)種特殊結構(gòu)的滑動軸承(cheng)。它的結構比(bǐ)滾動軸承簡(jiǎn)單，其主要是(shi)由一個有外(wài)球面的内🆚圈(quan)和一個有内(nèi)球面的外圈(quān)組成，能承受(shou)較大的負💃🏻荷(he)，根據其不同(tong)的類型和結(jié)構💘，可以承受(shòu)徑向負荷、軸(zhou)向負荷或徑(jìng)向、軸向同時(shí)存♋在的聯合(he)負荷。關節軸(zhóu)承一般用🏃🏻于(yu)速度較低的(de)擺動運動（即(ji)角運動），由✏️于(yu)滑動表面為(wei)球面形，亦可(kě)在一定角度(du)範圍内作傾(qīng)斜運動🔅（即調(diao)心運動），在支(zhi)承軸與🍓軸殼(ké)孔不同心度(du)較大時，仍能(neng)正常工作。應(ying)用于工程液(yè)🏃🏻壓油缸,鍛壓(yā)機床,工程機(ji)械,自動化設(shè)備，汽車減震(zhen)器，水利機🍉械(xie)等行業。
Joint bearing is a special structure of sliding bearing. Its structure is simpler than the rolling bearing. It is mainly composed of an inner sphere with an outer sphere and an outer ring with an inner sphere. It can bear a large load. According to its different types and structures, it can bear the joint load of radial load, axial load or radial and axial. Joint bearings are generally used for low speed swinging motion (angular motion). Because the sliding surface is spherical and can also be tilted in a certain angle range, it can still work normally when the degree of inconcentricity of the supporting axis and the shaft shell is large. It is applied to engineering hydraulic cylinder, forging machine, engineering machinery, automation equipment, automobile shock absorber, water conservancy machinery and so on.
