一、前言 X—Y型传动,是一种新的结构形式的行星传动,其优点是结构紧凑,在同样条件下,体积仅为一般传动的五分之一,可节约较多钢材。与同功率减速器相比电机可相应选得小些,故可节能。转矩和传动比成线性关系,内齿轮啮合齿数随转矩增大而增加,从而使各轮齿受 I. Introduction X-Y type transmission is a new type of planetary transmission with the advantage of compact structure. Under the same conditions, the volume is only one-fifth of the normal transmission, which can save more steel. Compared with the same power reducer motor can be selected accordingly smaller, it can save energy. Torque and transmission ratio into a linear relationship, the number of internal gear meshing increases with the increase of torque, so that each gear by
