零齿差输出机构,就是通过一对齿数相同(即齿数差为零)的内啮合齿轮副,而且在适当中心距的平行轴间啮合,以传动比为1将行星轮的反向低速自转运动传出,只起传递作用,不起减速作用的零齿差输出的W机构。这种结构形式零件较少、结构紧凑、使输出机构大大简化。用标准刀具在通用机床上加工,易于提高精度。本文将有关啮合方程,正确啮合的限制条件作一专述。
Zero tooth differential output mechanism, that is, through a pair of teeth with the same number (that is, the number of teeth is zero) of the internal gear pair, but also in the appropriate center distance between the parallel axis meshing with a gear ratio of 1 will reverse the low-speed planetary gear rotation Out, only from the transmission role, can not afford to slow down the zero-tooth differential output W institutions. The structure of the parts less, compact structure, the output mechanism greatly simplified. With standard tools in general-purpose machine tool processing, easy to improve accuracy. In this paper, we will make a special statement about the meshing equations and the conditions for the correct meshing.
