關節軸承是一(yī)種特殊結(jié)構的(de)滑動軸承。它的結構比滾動軸承簡單，其主要(yào)是由一個有外(wài)球面的内圈(quān)和(hé)一個有(yǒu)内(nèi)球面(miàn)的外圈組成，能(néng)承受(shòu)較(jiào)大的負荷，根據其(qí)不同的類(lèi)型和結構，可以承受(shòu)徑向負荷(hé)、軸向負荷(hé)或徑向、軸向同時存在的聯合(hé)負荷。關(guān)節軸承(chéng)一般用于速度(dù)較低的擺(bǎi)動運(yùn)動（即(jí)角(jiǎo)運(yùn)動），由(yóu)于(yú)滑動表面為(wéi)球面形，亦可在(zài)一定(dìng)角度(dù)範圍(wéi)内作傾(qīng)斜運動(dòng)（即調心運(yùn)動），在(zài)支承軸與軸殼(ké)孔不同(tóng)心(xīn)度較大時(shí)，仍能正常(cháng)工作。應用于工(gōng)程液壓油缸,鍛(duàn)壓機床,工程機(jī)械,自動化設備(bèi)，汽車減震(zhèn)器，水(shuǐ)利機(jī)械等(děng)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.
