Basing on the requirement of the project supported by chongqing science and technology committee , the study and development on original non - frictional and sequential operation ' s stepless speed regulator , the author has made some analysis to the physical principle and speed adjustment principle . in addition , as the main part of stepless speed regulators , the transformer was more concerned in the study . after probing the creation of its structure principle , this paper reveals its structure and dynamics rule , and creates a dynamics model and synthesis model of transformer 根据重庆市科委技术攻关项目《新型非摩擦式连续作用机械无级变速器的研制与开发》的要求，对该无级变速器的工作原理、调速原理及工作性能进行分析，并着重对无级变速器的核心部件转换器进行分析，对其结构原理创新进行深入的探讨，揭示了其结构及运动学的实质；建立了转换器的运动学模型和综合模型；对以转换器这类以连杆作为输出构件的曲柄摇杆机构的运动规律及其影响因素，首次进行了较深入、系统的分析研究，得出了一系列以连杆作为输出构件的曲柄摇杆机构的运动规律。
