On the Creation of New Conjugate Kinematic Pairs - Theory and Application

该研究项目旨在建立一种生成新的共轭运动副的设计方法。基于这种方法，将开发出用于运动和动力传输的新型高性能运动副，如齿轮、转子和凸轮。该项目背后的驱动动机有三个方面：(i)为机械系统创造新的共轭运动副的实际和分析意义；偏差函数法在圆和非圆螺距曲线生成新的共轭对中的优点；（三）在相当长的一段时间内，特别是在美国，对这一重要研究领域缺乏关注。在研究阶段，计划重点开展以下四个重点研究：1.重点研究；基于偏差函数的共轭副设计方法2. 高承载能力齿轮设计；3. 新型非圆齿轮齿形设计和4。设计先进的叶片泵。这些研究进一步细分为11个精心设计的子任务，即设计分析、设计综合、高负载能力廓形研究、齿轮共轭性能评估、实用性考虑、实验、压力角考虑、干扰避免、高抽运效率设计、流量设计和高压叶片泵的设计与测试。＊＊＊

9812847 Yang This research project is aimed to establish a design methodology for generating new conjugate kinematic pairs. Based on this method, new high performance kinematic pairs, such as gears, rotors, and cams for motion and power transmission, are to be developed. The driving motivation behind the project is threefold: (i) The practical and analytical signficance of creating new conjugate kinematic pairs for mechanical systems; (ii) The advantages of Deviation-Function (DF) method in generating new conjugate pairs for both circular and non-circular pitch curves; and (iii) The lack of attention devoted to this important area of study for a relatively long period of time, particularly in the United States. During the research phase, it is planned to emphasize the following four focus studies: 1. a deviation-function based design methodology for creating new conjugate pairs; 2. design of High-load-capacity gears; 3. new tooth profile design for non-circular gears; and 4. design of advanced lobe pumps. These studies are further broken down into eleven carefully designed sub-tasks, namely, design analysis, design synthesis, research for high- load-capacity profiles, evaluation on gear conjugation properties, considerations on practicality, experimentation, pressure angle consideration, interference avoidance, design of high pumping efficiency, design of flow rate, and the design and testing of high-pressure lobe pumps. ***
