AE20单向离合器

AE20单向离合器技术参数表

     AE型是滚柱式单向离合器，无轴承支撑。使用时需配合轴承安装，以承受轴向载荷与径向载荷。使用时需加注润滑脂。采用油润滑。公称外径是一个标准的球轴承尺寸。

     这种离合器的典型使用就是与一个具有相同定位公差的轴承一起安装。离合器的内圈用键固定在轴上，外圈有h6等级的正公差，可以压入公差等级为K7的座孔，外圈端面键槽传递正向扭矩。如果座孔的公差等级是R6，就不需要键槽，但外圈座必须有足够的强度，避免装配后变形。

     内外圈的设计允许轴向有±S∕2的偏差。

    Type AE is a roller type freewheel non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation.Standard lubrication is oil. Nominal outside diameter is a standard ball bearing dimension.

    A typical arrangement is to install this type beside a bearing with the same housing diameter tolerance.The inner race is keyed to the shaft. The outer race has a h6 tolerance and should be fitted in a housing with a K7 tolerance.Additional side notches provide for positive torque transmission. If the housing tolerance is to R6,use of the notches is not necessary,but the housing must be strong enough to not expand after assembly. 

    This design can accept an axial misalignment of inner and outer race of ±S/2 。
