C型密封深溝球等截面薄壁軸承概述
深溝球軸承結(jié)構(gòu)簡單,與別的類型相比易于達(dá)到較高的制造精度,所以便于成系列大批量生產(chǎn),制造成本也較低,使用普遍。選取較大的徑向游隙時(shí)軸向承載能力增加,承受純徑向力時(shí)接觸角為零.有軸向力作用時(shí),接觸角大于零。一般采用沖壓浪形保持架,車制實(shí)體保持架,有時(shí)也采用尼龍架.深溝球軸承除基本型外,還有各種變型結(jié)構(gòu),如:帶防塵蓋的深溝球軸承; 帶橡膠密封圈的C型密封薄壁深溝球軸承;有止動(dòng)槽的深溝球軸承;有裝球缺口的大載荷容量的深溝球軸承;雙列深溝球軸承.但是它們都有以下共同特點(diǎn):
1、在結(jié)構(gòu)上深溝球軸承的每個(gè)套圈均具有橫截面大約為球周長的三分之一的連續(xù)溝型滾道.它主要用于承受徑向載荷,也可承受一定的軸向載荷;
2、在軸承的徑向游隙增大時(shí),具有角接觸球軸承的性質(zhì),可承受兩個(gè)方向交變的軸向載荷;
3、摩擦小,轉(zhuǎn)速高;
4、結(jié)構(gòu)簡單,制造成本低,容易達(dá)到較高的制造精度;
5、一般采用沖壓浪形保持架,內(nèi)徑大于200mm或高速運(yùn)轉(zhuǎn)的軸承,采用車制實(shí)體保持架。
