外球面球軸(zhóu)承實際上是(shì)深溝球軸承(chéng)的一種變型(xíng),特😘點是它✌️的(de)外圈外徑表(biǎo)面為球面可(kě)以配入軸承(cheng)座相應的凹(āo)球面内起到(dào)調心的作用(yong)。主要用來承(chéng)受以徑向負(fù)荷為主的徑(jing)向與軸向聯(lian)合負荷,一般(ban)不宜單獨承(chéng)受軸向👉負荷(he),此種軸承可(kě)以分别安裝(zhuang)内圈(帶全組(zǔ)滾子與保持(chí)器)和外圈。該(gāi)種軸承軸向(xiang)遊隙的大小(xiao),對軸承能否(fǒu)正常工作關(guan)系很大🛀🏻,當軸(zhou)向遊隙過小(xiǎo)時,溫升較高(gāo):軸向遊隙較(jiào)大時,軸承容(rong)易損壞。故在(zài)安裝和運轉(zhuan)時要特别注(zhu)意調整軸承(cheng)的軸向遊隙(xì),必要時可以(yǐ)預過㊙️盈安裝(zhuāng),以增加軸承(chéng)💞的剛。常用于(yu)采礦🤟、冶金、農(nóng)業、化工、輸送(song)等機械上。
In fact, Pillow Block Ball Bearing is a variant of the deep groove ball bearing, which is characterized by the effect of the surface of the outer diameter of its outer ring as the spherical surface of the ball bearing the corresponding concave spherical surface of the bearing seat. It is mainly used to bear radial and axial joint loads based on radial load. It is not suitable for axial load alone. This kind of bearing can be installed in the inner ring (with all the rollers and maintainers) and the outer ring. The size of the axial clearance of this kind of bearing has a great relationship with the normal work of the bearing. When the axial clearance is too small, Wen Sheng is higher: when the axial clearance is large, the bearing is easily damaged. Therefore, when installing and running, we should pay special attention to adjust the axial clearance of bearings, and install prestress when necessary, so as to increase the rigidity of bearings. It is often used in mining, metallurgy, agriculture, chemical industry, transportation and other machinery.
