    摘要:

    针对非圆齿轮的时变速比特性,采用多段函数构造法实现了非圆齿轮副预设速比函数的再现设计;结合工程实际,提出了一种新型的非圆齿轮无级调速机构,推导了非圆齿轮无级调速机构的基本参数与输出速比的影响规律。根据机械原理、齿轮啮合理论与现代设计方法,采用SolidWorks和Adams等软件,建立了非圆齿轮无级调速机构的仿真模型,对非圆齿轮无级调速机构进行仿真,结果表明:改变非圆齿轮副间的相位差,该无级调速机构可以得到变化的输出速比,获得了该无级调速机构的输出速比与相位差的影响规律;搭建了非圆齿轮实验台,得到非圆齿轮副的实验速比与理论速比变化趋势一致,最大实验误差6.8%,验证了无级调速机构和非圆齿轮理论分析的可行性和正确性。

    Abstract:

    On the basis of the multi-segment function construction method, the reproduction design of non-circular gear pairs with preset time-varying transmission ratio is proposed. Combined with the practical application of non-circular gear pairs in industry, a new continuously variable transmission mechanism with non-circular gear pair is presented. The influence of basic parameters of non-circular gear on output transmission ratio is discussed. By using software, such as SolidWorks and Adams, the simulation model of this continuously variable transmission mechanism is established. The simulation results show that a variable output speed ratio can be obtained by changing the relative phase angle of non-circular gear pair, and the influence of the relative phase angle on the output speed ratio is revealed. A non-circular gear pair experimental platform is built, and the experimental results show that the change trend of the experimental transmission ratio is consistent with that of the theoretical transmission ratio, with the maximum experimental error of 6.8%, demonstrating the feasibility and correctness of the theoretical analysis of this variable transmission mechanism.
