本文分析了齿形带带齿与齿带轮轮齿之间的侧隙、齿形带的弹性伸长及带齿侧面变形三因素与齿形带直线传动移动件返程误差之间的关系，得到了诸结构参数对返程误差影响的变化趋势。
In this paper, the relationship between the backlash between toothed belt teeth and the teeth of the toothed pulley, the elastic elongation of the toothed belt and the deformation of the toothed flanks and the return error of the toothed belt linear transmission moving parts are analyzed. The structural parameters of the return error of the changing trend.
