齿廓重合度 Profile contact ratio
Though the involute profile is easy to design and manufacture, it also brings the inherent problem of oil trapping. In addition, the meshing of two convex teeth make the relative radius of curvature of the contacting point shorter.
齿轮泵转子的齿廓型线一般为渐开线，渐开线型线虽设计加工方便，但存在原理性的困油现象；凸凸齿廓啮合使两齿轮在接触点处的综合曲率半径较小；当齿数较少时，渐开线齿轮存在根切现象。
