冲压外圈滚针轴承为具薄型冲压成型外圈的滚针轴承。
特点:
1.截面高度很低而承受负荷能力较高。
2.主要用于结构紧凑、价格便宜且轴承箱内孔不能作为滚针保持架组件滚道的轴承配置。
3.采用过盈静止配合,不需要轴向固定装置.即使在高速、大负荷条件下,也能确保其灵活工作性能。
4.冲压外圈滚针轴承一般不附内圈。在轴颈无法淬硬和研磨的场合,可以采用专用内圈。
5.冲压外圈滚针轴承的淬硬钢板外圈与滚针保持架组件不可分离。
6.轴承一般采用单列设计。较宽规格的轴承1522,1622,2030,2538和3038等除外,它们装有二个滚针保持架组件。
7.根据用户需要,轴直径大于或等于7mm的所有单列冲压外圈滚针轴承都可配备带润滑油孔的外圈(代号后缀AS1)。
8.冲压外圈滚针轴承先进原理是体内封脂容积大,可长期不加润滑,由于耐高温润滑间隔,从而保证其长期运转无忧。
9.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。
分类:
1.双侧敞开式;2.单侧封闭式(适用于轴端且可承受小的轴向游动力)

1.轴承座孔公差带:钢或铸铁N6(N7);轻金属R6(R7)
2.轴公差:无内圈H5(h);有内圈K5(j)
3.冲压外圈滚针轴承的宽度偏差是_00.25mm
4.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。
装配注意事项:
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。
3.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。
4.装配前应当注入足够的润滑脂。
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“设计注意事项”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。
