摘　　要：三组元比例控制器是水下热动力能源供应系统的关键组件,如何保证推进剂组元的精确比例配比,是比例控制器研制需要解决的主要问题。文中提出了一种采用2阶椭圆齿轮结构的比例控制器,其弥补了叶片式比例控制器的不足。依据2阶椭圆齿轮的啮合原理以及齿形折算原理,得到了齿轮在节曲线上的分布特点。利用CAXA/UG计算机辅助设计技术,设计了2阶椭圆齿轮的齿形并进行了比例控制器用椭圆齿轮的建模及齿轮运动副的运动仿真。仿真结果可为新型2阶椭圆齿轮结构的三组元比例控制器设计及加工提供参考。The tri-proportion controller is the key component of underwater thermal energy supply systems.Ensuring the accurate proportional ratio of the propellant components is the main problem to be solved in the development of the proportional controller.In this study,a proportional controller with a second-order elliptic gear structure is proposed,which compensates for some shortcomings of the blade scale proportional controller.The distribution characteristics of the gear on the joint curve are obtained according to the gear meshing and convert tooth principle of second-order elliptic gears.The tooth shape of this gear is designed using the CAXA/UG computer-aided design technology.Modeling and motion simulation of this elliptic gear,which is used in the proportional controller,are thereafter performed.The simulation results can be used as a theoretical reference for the design and processing of the tri-proportion controller of this second-order elliptic gear structure.
