摘　　要：基于DZLY180型减速器,针对点线啮合齿轮齿廓的特殊性,利用点线啮合齿轮齿廓的曲线方程,计算修形后齿廓曲线上的若干坐标,通过三次样条曲线对其进行拟合,并运用三维软件Solid Works拟合出修形后的点线啮合齿轮的齿廓曲线,然后进行三维建模,并完成了齿轮的无干涉装配,仿真表明该方法实现了点线啮合齿轮在啮合过程中全局无干涉。Based on the type of DZLY180 gear reducer,aiming at the particularity of the tooth profile of point- line meshing gear,the curve equation of the tooth profile of point- line meshing gear is applied to calculate some coordinates on the tooth profile curve after modification. The cubic spline curves are used to fit the data,and 3D Software Solidworks is used to fit the tooth profile curve of point- line meshing gear. Then the three- dimensional modeling is carried out,the interference- free assembly of the gear is completed. The simulation results show that,the overall interference- free assembly in the meshing process of the point- line meshing gear is realized by the method.
