安装及选用 Installation and selection

要保证旋转运动的等角速和主、从动轴之间保持同步转动，应选用双十字轴万向联轴器或两个单十字轴万向联轴器组合在一起，并满足以下三个条件：a中间轴与主、从动轴间的夹角相等，b中间轴两端叉头的对称面在同一平面内x中间轴与从动轴线在同一平面内，安装单十字轴万向联轴器时，主、从动端角度不等，主、从动轴之间不能保持同步转动；其不同步性随着夹角变而变。

To ensure the constant angular speed of rotation and the synchronous rotation between the main and driven shafts, double spider universal couplings or two single spider universal couplings should be selected and combined, and the following three conditions should be met: a The included angle between the intermediate shaft and the main and driven shafts is equal, b The symmetry plane of the fork heads at both ends of the intermediate shaft is in the same plane x The intermediate shaft and the driven shaft are in the same plane. When installing the single spider universal coupling The angle of the driven end is different, and the driving and driven shafts cannot keep synchronous rotation; Its asynchrony changes with the included angle.
