冲压外圈滚针轴承的外圈是用薄钢板精密冲压成型的,结构空间小,且具有较大负荷容量。适用与安装空间受到限制和壳体孔不宜作为滚道的场合,且压入轴承座孔后不必进一步轴向定位。
该类滚针轴承一般不用内圈,但如果需要使用内圈,可从本样本中选取。
同穿孔型冲压外圈滚针轴承相比,封口型冲压外圈滚针轴承对轴端部位的密封极为有效。由于该类滚针轴承有润滑脂(锂基脂),在使用温度为-20~+120℃的范围类,可长期运转。

2、检验
由于薄壁外圈在热外理后产生变形,所以冲压外圈滚针轴承尺寸业精度在安装前无法检验。只有当轴承压入到具有推荐公差极限的轴承座孔时,轴承才能达到所有必需的配本精度。
冲压外圈滚针轴承滚针组内切圆直径(Fw)偏差的栓验方法如下:
现将轴承压入标准圈,再用圆术形极限塞规检查滚针组单一最小内径偏差。
成套轴承滚针组单一最小内径偏听偏信差表1规定。
标准圈尺寸和公差按表2规定。
塞规按表3规定。

3、 配合公差及装配
3.1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寸和几何精度。座孔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,若座孔公差按表4规定选取,则轴承装配到刚性座孔中时,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,则可行到正常的工作间隙。
表4轴承座孔与轴的尺寸公差
轴承座材料(刚性轴承座) | 轴承座孔公差带 | 轴公差带 |
钢或铸铁 | N6 | h5 |
轻金属 | R6 |
3.2、装配
冲压外圈滚针轴承借助于装配心轴压入轴承座孔中,装配心轴轴肩应与轴承有打印标记的一端相接,装配心轴环形槽装有一O型密电码封圈,使轴承不易脱落,在安装过程中不能使轴承发生倾斜。
