Design and analysis of novel gears with high load-carrying capacity and low sliding rate
基于曲线型啮合线设计了一种高承载能力低滑动率新型齿轮,借助微分几何和空间啮合理论,通过预设抛物线啮合线推导新型齿轮齿廓方程,计算新型齿轮重合度和齿面滑动率.利用Matlab编程仿真齿轮加工过程,实现新型齿轮参数化高精度三维有限元网格建模.在此基础上,通过轮齿承载接触分析,深入分析安装误差、齿面修形等对新型齿轮齿面接触应力和齿根弯曲应力的影响.结果表明:与渐开线齿轮相比,设计的新型齿轮重合度明显提高,传动更加平稳;齿面相对滑动率降低22.9%,啮合…查看全部>>
A novel gear with high load-carrying capacity and low sliding rate was designed based on a curved path of contact.Through differential geometry and spatial meshing theory,the novel gear profiles were derived from the preset parabola path of contact,and calculations of the contact ratio and the sliding rate of the novel gears were carried out.The parametric high-precision three-dimensional finite element meshing modeling of novel gears was obtained based on t…查看全部>>
