關(guān)節(jié)軸承是一種特殊結(jié)構(gòu)的滑動軸承。它的結(jié)構(gòu)比滾動軸承簡單，其主要是由一個有外球面的內(nèi)圈和一個有內(nèi)球面的外圈組成，能承受較大的負荷，根據(jù)其不同的類型和結(jié)構(gòu)，可以承受徑向負荷、軸向負荷或徑向、軸向同時存在的聯(lián)合負荷。關(guān)節(jié)軸承一般用于速度較低的擺動運動（即角運動），由于滑動表面為球面形，亦可在一定角度范圍內(nèi)作傾斜運動（即調(diào)心運動），在支承軸與軸殼孔不同心度較大時，仍能正常工作。應(yīng)用于工程液壓油缸,鍛壓機床,工程機械,自動化設(shè)備，汽車減震器，水利機械等行業(yè)。

      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.
