C型密封深溝球等截面薄壁軸承概述
深溝球軸承結構簡單,與別的類型相比易于達到較高的制造精度,所以便于成系列大批量生產,制造成本也較低,使用普遍。選取較大的徑向游隙時軸向承載能力增加,承受純徑向力時接觸角為零.有軸向力作用時,接觸角大于零。一般采用沖壓浪形保持架,車制實體保持架,有時也采用尼龍架.深溝球軸承除基本型外,還有各種變型結構,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:
1、在結構上深溝球軸承的每個套圈均具有橫截面大約為球周長的三分之一的連續溝型滾道.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,具有角接觸球軸承的性質,可承受兩個方向交變的軸向載荷;
3、摩擦小,轉速高;
4、結構簡單,制造成本低,容易達到較高的制造精度;
5、一般采用沖壓浪形保持架,內徑大于200mm或高速運轉的軸承,采用車制實體保持架。
