摘　　要：以非圆齿轮的啮合原理为依据,利用MATLAB计算机辅助软件,对偏心圆齿轮副的啮合特性和数字化制造技术进行了研究,根据对偏心圆齿轮的节曲线、传动比、啮合特性及凹凸性分析,证明了这类齿轮传动的可行性。通过对其齿形的设计分析,利用CAD/CAM软件,以一阶偏心圆齿轮副为分析设计实例,绘制出其三维模型,并对其进行模拟加工,验证了非圆齿轮的设计理论在此类齿轮的设计、制造中的可行性,这为偏心圆齿轮的设计和生产应用提供了依据。According to the meshing principle of non-circular gears, the meshing characteristic and digital manufacturing technology of Eccentric gears is studied based on Matlab. Based on analyzing the parameterized modeling of pitch curve, transmission characteristics and convexity-concavity analysis on Eccentric gears, the transmission feasibility of this type gear is proved. Through tooth shape design, CAM calculation and analysis with example, and processing simulation, the validity and manufacturability of theoretical design method on this type gear is proved. The research results can provide more systemic theory basis for the design, manufacture, measure and application of Eccentric gears.
