中文摘要：

液粘传动具有启动冲击小、无极调速、过载保护等性能优点,广泛应用于大能耗设备的调速启动及运行速度控制。但是传动机理和精密、耐磨以及长寿命的液粘传动关键零件的设计制造是制约其应用的瓶颈。本文阐述了液粘传动机理、液粘传动摩擦副间流体的流场特性、液粘传动设备摩擦副设计及材料选型等,在系统分析现有研究成果的基础上,提出了采用耦合激光微造型和反变形对对偶片进行结构和表面微织构主动设计制造的思想,以减小对偶片型面的变形。

英文摘要：

Hydro-viscous drive is widely used in large power consumption equipment speed starting and speed control because of its performance advantages of small start-up impact,non-grade speed adjustment,overload protection. While the hydro-viscous transmission mechanism and the design and manufacture of key parts with the characteristics of precise,the abrasion-proof and long-life of hydro-viscous drive are the bottlenecks for the broaden application. The research progress on hydro-viscous transmission mechanism,the fluid flow field characteristics of hydro-viscous drive friction pair and principles of hydro-viscous drive friction pair design and it＇s material selection are induced specifically. On the basis of comprehensive analyzing and summarizing the existing research results,a new research idea coupling the reverse deformation with laser texturing technology for the function-oriented structure design and surface micro texture on dual palate to minimize the surface deformation is put forward.
