摘　　要：针对机械联接的自由度与约束问题,研究了运动学传动设计的旋量方法,给出了点接触约束与自由度旋量的数学描述及相互关系,并从几何角度阐述了旋量系的对偶性。以丝杠与直线平台的过约束联接为例,将力偶约束转化为等价的点接触约束,进而应用旋量系理论提出了一种新型运动学传动联接。该联接具有结构简单、便于装配的优点,同时具有更加紧凑的结构环,在机械工程领域具有广泛应用。Aiming to over-constrained couplings between a lead-screw and a linear guide, a screw theory approach for kinematic transmission design is developed, the interrelationship between point contact constraints and freedom twist and methods of description are presented. Couple constraints in couplings between lead-screws and linear guides are transformed into point contact constraints, furthermore a new kinematic transmission coupling is proposed. The coupling structures are simple and ease to assembly, and have a tighter structural loop. The coupling will be used widely in mechanical engineering.
