旋转轨的安装
    1)横向轴、竖向轴、环柱轮和辅轮(图5.3和图5. 10)全部是外协加I件,安装前
对零件进行尺寸和加工光洁度的检查,检查合格后再安装。
    2)滚动轴承在环柱轮和辅轮及横向轴和竖向轴的装配。
    a.装配轴承前要检查与轴承相配的轴和轮的孔配合尺寸是否符合图纸要求,并用汽
油或煤油清洗,仔细擦净,然后涂上一层薄薄的油。
    b.检查轴承型号是否与图纸要求一致,并清洗滚动轴承,可用汽油或煤油擦洗滚动
轴承内孔和外圈表面,并用软皮擦净。
    c.装配环境中不得有金属微粒、金属屑、砂子等,新轴承从包装盒取出必须尽可能
使它们不受灰尘污染,最好在无尘室中装配滚动轴承。
    d.先装轮中的弹簧挡圈,然后再装轴承和轴。
    e.装配滚动轴承时不得直接敲击滚动轴承内外圈、保持架和滚动体,否则会破坏滚
动轴承的精度,降低滚动轴承的使用寿命。
    f.装配的压力直接加在待配合的套圈端面上,绝不能通过滚动体传递压力。
    g.对于所用的较小轴承,轴承套圈的压人方法一般采用套筒压人法,其配合过盈量
较小,常用工具为冲击套筒与手锤,以保证滚动轴承套圈在压人时均匀敲入。
    3)将装配好的横向轴、滚动轴承、弹簧挡圈、环柱轮装在旋转轨的位置上,将竖向
轴、滚动轴承、弹簧挡圈和辅轮装到旋转轨的垂直方向。
    4)将旋转轨分两半装在固定轨上,两半旋转轨再用销轴和螺栓螺母连成一个整轨。
旋转轨可以靠环柱轮和辅轮在固定轨上旋转。
