NTN进口轴承NTN圆锥滚子轴承
NTN圆锥滚子轴承主要承受以径向为主的径、轴向联合载荷。轴承承载能力取决于外圈的滚道角度,角度越大承载能力越大。该类轴承属分离型轴承,根据轴承中滚动体的列数分为NTN单列、NTN双列和四列圆锥滚子轴承。NTN单列圆锥滚子轴承游隙需用户在安装时调整;双列和四列圆锥滚子轴承游隙已在产品出厂时依据用户要求给定,不须用户调整。 NTN圆锥滚子轴承有圆锥形内圈和外圈滚道,NTN圆锥滚子排列在两者之间。所有圆锥表面的投影线都在轴承轴线的同一点相聚。这种设计使NTN圆锥滚子轴承特别适合承受复合(径向与轴向)负荷。轴承的轴向负荷能力大部分是由接触角 α 决定的; α 角度越大,轴向负荷能力就越高。角度大小用计算系数 e 来表示; e 值越大,接触角度越大,轴承承受轴向负荷的适用性就越大。
NTN圆锥滚子轴承通常是分离型的,即由带滚子与保持架组件的内圈组成的圆锥内圈组件可以与圆锥外圈(外圈)分开安装。
