摘要
谐波齿轮减速器的间隙空程来源复杂,是影响机构运动精度的主要因素。根据谐波减速器的工作原理分析,引起间隙空程的主要因素是零件扭转变形(柔轮和输出轴)、柔轮刚轮齿侧间隙和柔性轴承的径向游隙;运用渐开线、材料力学和刚度等理论,建立了间隙空程与上述因素的数学模型;开展了某种谐波减速器的间隙空程测试,实测结果与理论计算值吻合。
The sources of the harmonic gear reducer gap clearance are complicated,the gap clearance is the main factor affecting the operation accuracy of the mechanism.According to the work principle of the har.monic gear reducer,the main factors causing the gap are the torsional deformation of the parts(the flexible wheel and output shaft),and the clearance between the rigid and flexible wheels,and the radial clearance of the flexible bearing.Secondly,using the theory of involute,material mechanics,stiffness and so on,the mathemat.ical model of the gap clearance and above factors is established.Finally,a gap-free test of one kind of harmonic gear reducer is carried out,the measured results are in good agreement with the theoretical calculation.
