对滚动伸缩式万向传动轴的分析研究

Mechanical Analysis on New Type of Roll Expansion Cardan Shaft

对“滚动伸缩式万向传动轴”机构在进行结构分析和运动分析的基础上作了受力分析。指出这种万向轴在传动中十字头将受到一个附加力矩的作用，影响其正常传递驱动力矩，在轴承及滚道结构设计上必须给予充分注意。

Based on the structural and dynamic analyses of the roll expansion cardan shaft,it is pointed out that the crosshead of this cardan shaft will be subjected to an additional force which will influence the transferring torque reliably,and it is necessary to pay more attention to design the needle bearing and the race way.
