怎么判断角接触轴承装反了?

角接触轴承怎么判断正反装,角接触轴承一般是成对安装来提升整体性能的,常见的三种安装方式分别是背对背(反装)、面对面(正装)和串联排列。根据具体使用的场景来选择适合的安装方法。那么下面中大小编就给大家介绍一下角接触轴承怎么判断正反装?
1、六类精密轴承的正装:正装就是面对面安装两轴承外圈的窄边相对,即内部轴向力指向相对,正装时轴距短。安装时轴承的接触角线朝回转轴线方向收敛,其地承角度刚性较小。由于轴承的内圈伸出外圈,当两轴承的外圈压紧到一起时,外圈的原始间隙消除,可以增加轴承的预加载荷;
2、六类精密轴承的反装:反装也就是背对背安装,两轴承外圈的宽边相对,即内部轴向力指向相背。反装时跨距长,轴刚度小。反装时,轴承的接触角线沿回转轴线方向扩散,可增加其径向和轴向的支承角度刚性,抗变形能力达到上限;
3、轴承正反转判断方法:观察外圈,外圈比较薄的一面是正面,反之为背面。角接触轴承正面就是外圈薄的一面,反面就是外圈厚的一面,轴承上一般有“<”的符号,开口对着的面是正面,尖角对着的面是反面。正装反装的区别主要在安装方法上。
