中文摘要	通过建立夹紧效率和夹持补正量的数学模型,对浮动式动力卡盘的静态夹持特性进行研究。研究结果表明:卡盘的夹紧效率不仅直接影响力传递系数,而且影响静态夹紧力的稳定性;夹紧效率越高的结构,由于润滑环境恶化而造成的静态夹紧力损失越小;浮动式动力卡盘在工作时,所夹持的工件的直径越小,卡盘的夹紧效率越低;浮动式动力卡盘的夹持补正量与杠杆传动比、浮动套和导套之间的配合间隙成正比,比例系数是浮动套的楔角和杠杆两臂的夹角的函数;通过建立浮动式动力卡盘的运动传递系数和夹持补正量之间数学关系,对浮动式卡盘的夹紧和补偿2个功能进行综合,实现浮动式卡盘的优化设计。; In order to study the static clamping characteristics of power-operated compensating chuck, a mathematic model for the clamping efficiency and compensating dosage of the chuck was developed. The investigation performed shows that the clamping efficiency of chuck not only directly affects the coefficient of force transfer but also the stability of static clamping force against the deterioration of the lubrication. The chuck structure which has a higher clamping efficiency will have a fewer static clamping force loss caused by the enlargement of friction. While the compensating chuck is working, the smaller the diameter of workpiece chucked is, the lower the clamping efficiency will be. The compensating dosage is proportional to the product of lever ratio and the clearance space between the floating sleeve and the guide bushing, and its proportion depends on the wedge angle of floating sleeve and the angle between the two arms of lever. Based on the establishment of mathematical relationship between the coefficient of force transfer and compensating dosage, the optimized design method for floating chuck is put forward considering fully the realization of clamping and compensating function.
