切线极坐标在仪表齿形研究中的应用

本文讨论了在仪表齿形研究中如何建立切线极坐标系，并在切线极坐标系中描述齿轮的运动关系以及怎样计算传动性能。同时，针对难以用直角坐标系描述的定力矩比齿轮，利用切线极坐标简洁地列出了齿轮的啮合方程式以及齿廓曲线表达式。

Applications of tangential polar coordinates in instrument gear research

n this paper,author discussed how to set up tangential polar coordinates in instrument gear research,how to describe the motion relationship of gear and how to calculate the drive performance under tangential polar coordinates.In addition.in view of constant torque ratio gear that is difficult to describe using Cartesian Coordinates,author set out the meshing equations and expression of gear's profile under tangential polar coordinates.
