电缆或金属带绞盘驱动器被用作旋转传动元件，因为它们具有非常低的侧隙（名义上为零）和高刚度特性。特别地，在许多类型的设备中发现线缆驱动器，并且为了获得高刚度，线缆通常以8字形图案缠绕在输入和输出鼓轮周围。本文提出了一种分析方法，用于预测绞盘驱动器的扭转刚度，使设计人员能够在设计研究阶段更好地评估机器的性能。实验验证了分析。
Cable or metal band capstan drives are used as rotary transmission elements for their very low (nominally zero) backlash and high stiffness properties. Cable drives, in particular, are found in many types of equipment, and to obtain high stiffness, the cable is typically wrapped around the input and output drum in a figure-eight pattern. This paper develops analytical methods for predicting the torsional stiffness of capstan drives to enable designers to better assess machine performance in the design study phase. Experiments validated the analysis.
