推力轴承安装后的检验

  安装推力轴承时,应检验轴圈和轴中心线的垂直度。方法是将千分表固定于箱壳端面,使表的触头顶在轴承轴圈滚道上边转动轴承,边观察千分表指针,若指针偏摆,说明轴圈和轴中心线不垂直。箱壳孔较深时,亦可用加长的千分表头检验。
  推力轴承安装正确时,其座圈能自动适应滚动体的滚动,确保滚动体位于上下圈滚道。如果装反了,不仅轴承工作不正常,且各配合面会遭到严重磨损。由于轴圈与座圈和区别不很明显,装配中应格外小心,切勿搞错。此外,推力轴承的座圈与轴承座孔之间还应留有0.2—0.5mm的间隙,用以补偿零件加工、安装不精确造成的误差,当运转中轴承套圈中心偏移时,此间隙可确保其自动调整,避免碰触摩擦,使其正常运转。否则,将引起轴承剧烈损伤。
