冲压外圈滚针轴承

 [img]http:///UserFiles/Image/001(98).jpg[/img] SZ-穿孔型和封口型冲压外圈滚针轴承径向截面高度甚小;其外圈和保持架用金属冲压成型方法制造.此种轴承占用空间小,负荷能力大。外圈则需刚性支承以充分发挥其负荷能力。[img]http:///UserFiles/Image/002(52).jpg[/img]
  此种轴承用压入与配合装进座孔中,且无需进行轴向定位。
  如果与轴承配合的轴不淬硬,则应订购相应的内圈。
安装公差:
  通常,单列冲压外圈滚针轴承不带润滑油孔而双列轴承则带润滑油孔。
安装公差表:
轴承座材料
(刚性轴承座)轴承座孔公差带轴公差带
无内圈有内圈
钢或铸铁N6(N7)H5()h6K5(j6)
轻金属R6(R7)

1.对于非刚性轴承座,需进行安装试验,以确定所需要的轴公差极限来获得期限的工作间隙。
2.轴承座孔圆柱形几何精度必须在数值一半的范围内。
  只有当轴承压入座孔中时,冲压薄壁外圈才能获得其最终的尺寸和几何精度。座孔的尺寸和几何精度决定轴承内切圆直径的精度和安装后支承的好坏。倘若座孔公差能按表1规定选取,则轴承装配到刚性座体中时,滚针内切圆直径近似在公差带F8范围内。如果与给定的轴公差相配合,则可得到正常的工作间隙。
  冲压外圈滚针轴承的宽度偏差是_00.25mm
  装配时应借助于安装心轴压入座孔中、装配心轴轴肩应当与轴承标有代号的一面相接,在安装过程中,不能使轴承发生倾斜。
  装配前应当注入足够的润滑脂。
检验尺寸:
  由于薄壁外圈在制造中可能不圆,所以冲压外圈滚针轴承尺寸精度在安装前无法检验。只有压入到具有推荐公差极限的轴承座孔中,轴承才可达到所必需的几何精度。因此,应按下述方法检验尺寸。
  1.把轴承压入壁厚≥20mm,孔径尽寸符合表2所规定的标准圈中;
  2.用圆柱形塞规检查,通端可以凭其自重顺利进入滚针内切圆中,止端则不能进入。
