分析了三叉杆式万向联轴器采用调心轴承时输出转角和输入转角之间的关系式,并得出这种联轴器为准等角速传动万向联轴器的结论;讨论了轴偏转角大小对输出输入转角差值的影响,分析表明,这种联轴器中转角差值的变化周期是输入轴自转周期的3倍。
The relationship between the output angle and the input rotation angle when using the self-aligning bearing is analyzed. The conclusion is drawn that this kind of coupling is quasi-isokinetic transmission universal coupling. The influence of shaft deflection angle on the difference between the input and output angles is analyzed. The analysis shows that the variation period of the rotation angle difference in such a coupling is three times of the rotation period of the input shaft.
