【摘要】：针对传统金属带式无级变速器难以提供足够大扭矩的问题,介绍了一种新型机械式无级变速器—活齿无级变速器。在分析了活齿无级变速器的工作原理和活齿啮合原理的基础上,通过SolidWorks建立活齿无级变速器的几何模型,利用ANSYS Workbench对活齿单元中的核心部件—滑片进行有限元分析,得到了滑片的等效应力和等效应变云图。在分析计算结果的基础上,对滑片进行了优化设计,并对得出的优化模型进行静力分析,结果表明:滑片的厚度由2.5mm减小到1.6mm,变化率达到36%,优化效果明显,结构更加合理,为进一步研究活齿无级变速器提供了参考依据。
[Abstract]:Aiming at the problem that the traditional metal belt CVT is difficult to provide enough torque, a new type of mechanical CVT-movable tooth CVT is introduced. Based on the analysis of the working principle and the meshing principle of the movable tooth stepless transmission, the geometric model of the movable tooth stepless variable transmission is established by SolidWorks, and the sliding blade, the core part of the movable tooth element, is analyzed by ANSYS Workbench. The equivalent stress and strain cloud diagram of the slider are obtained. Based on the analysis and calculation results, the optimum design of the slider is carried out, and the static analysis of the optimized model is carried out. The results show that the thickness of the slider is reduced from 2.5mm to 1.6 mm, the change rate is up to 36%, and the optimization effect is obvious. The structure is more reasonable, which provides a reference for the further study of the movable teeth stepless variable transmission.
