Hy-Vo齿形链是机械传动领域中的一种高端产品系列。近年来，随着高速链传动技术的不断发展和主机不同的个性化实际需求的增长，Hy-Vo齿形链及其链轮呈现了不断变异的发展趋势，而这一变异的发展趋势正是对Hy-Vo齿形链传动技术的一大变革和创新。. 本项目主要研究了双相传动Hy-Vo齿形链系统的多元变异及其啮合机理。重点研究了双相传动Hy-Vo齿形链系统的双相叠加原理及其谐应关系、不同啮合机制链节有序排列规律及其变异啮合机制的设计准则、链及链轮的新齿形设计方法、链与链轮的接触动态响应和噪声频谱；通过研究揭示了双相传动Hy-Vo齿形链多元变异的耦合效应及其对系统多边形效应和中心距变动量的影响规律，并在分析研究Hy-Vo齿形链与链轮的啮合机制的基础上，根据Hy-Vo齿形链链轮与刀具齿条的共轭啮合条件，对Hy-Vo齿形链及其链轮进行变异设计，建立双相传动Hy-Vo齿形链-链轮-刀具设计体系，提出了双相传动Hy-Vo齿形链系统设计方法，构建了双相传动Hy-Vo齿形链啮合设计体系，并建立了相关啮合方程，提出了双相传动Hy-Vo齿形链-双相链轮-刀具系统的正确啮合条件，研究表明，双相传动Hy-Vo齿形链系统与其分解的任意一个单独运转的单相传动Hy-Vo齿形链系统的瞬时传动比不一定相同，不同的瞬时传动比对齿形链紧边中心线的波动量与齿形链多边形效应有着不同的影响，当双相链轮的节距与压力角均相等时，双相传动Hy-Vo齿形链系统与其分解的任意一个单独运转的单相传动Hy-Vo齿形链系统相比，双相传动Hy-Vo齿形链系统的多边形效应较小。形成了适用于双相传动的新型多元变异Hy-Vo齿形链系统的啮合设计理论与方法。
