一、概述谐波齿轮传动是由于发生器和柔轮的相对运动,迫使柔轮产生谐波变形,因而柔轮和刚轮的齿发生相对位移。在发生器的长轴区,柔轮和刚轮的齿进行啮合;在发生器的短轴区,则啮合逐渐脱开,随着发生器和柔轮的相对运动,啮合区也随之转移,从而达到传动的目的。谐波齿轮传动的啮合过程,也就是柔轮齿和刚轮齿之间相对运动的过程。啮合过程的合理与否直接影响参加啮合的齿的数目,
I. Overview Harmonic gear drive is due to the relative movement of the generator and the flexspline, forcing the flexspline to produce harmonic deformation, so that the flexure and the rigid wheel tooth relative displacement occurs. In the long axis area of the generator, the flexspline and the just-wheel tooth are engaged; in the short-axis area of the generator, the engagement is gradually disengaged; as the relative movement of the generator and the flexspline, the engagement area is also shifted, So as to achieve the purpose of transmission. Harmonic gear meshing process, that is, between the soft gear teeth and just the relative movement between gear teeth process. The rationality of the meshing process has a direct impact on the number of teeth participating in the meshing,
