外球面(miàn)球軸承實際(jì)上是深溝球(qiú)軸承的一種(zhǒng)變型,特♊點是(shì)它的外圈外(wai)徑表面為球(qiú)面可以配入(ru)軸承座相應(ying)的凹球♌面内(nèi)起到調心的(de)作用。主要用(yòng)來承受以徑(jing)向負荷為主(zhǔ)的徑向與軸(zhou)向聯合負荷(he),一般不宜單(dan)獨承受軸向(xiang)♉負荷,此種✌️軸(zhóu)承可以分别(bie)安裝🌈内圈(帶(dai)全組🌈滾子與(yu)保持器)和外(wai)圈。該種軸承(chéng)軸向遊隙的(de)大小,對軸承(cheng)能否正常工(gong)作關系很大(da),當軸向遊隙(xi)過小時,溫升(sheng)較高💛:軸向遊(you)隙🈲較大時,軸(zhóu)承容易損壞(huài)。故在安裝和(hé)運轉時要特(tè)别注意調整(zheng)軸承的軸向(xiang)遊隙,必要時(shi)可以預過盈(yíng)安裝,以增加(jiā)軸承的剛。常(chang)用于采礦、冶(ye)金、農業、化工(gōng)、輸送等機械(xiè)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.
