Research Tooth Profile Error Of ZK_Worm Based On 3D Simulation

In this dissertation ,on the basis of the full and accurate summing-up of the research status quo of the ZK_type worm, and according to its larruping trait-its tooth profile not only bears on worm parameters(m, z,d₁) but also tool parameters, using computer technology simulated the real machining process of the ZK_type worm. According to the results of the simulation ,it is analysed that the change trend of the ZK_type worm tooth profile follows both worm parameters(m, z, d₁) and tool parameters. Consequently, references to the real machining process of the ZK_type worm is put forward.The main contents as follows was presented:(l)Based on the principle that the cone grinding wheel process the ZK_type worm, the equation of the tooth profile was gained and the theoretic programme of the tooth profile creation was writed.(2)Based on the technology of the ActiveX Automation, AutoCAD was exploited secondly by Visual Basic and the three-dimensional simulation of the ZK_type worm machining was realized by boolean operation.(3)Compared the the theoretic tooth profile with the shape of the simulation profile.the distributing law of errors was drew on and the reasons was analysed.The conclusions in this thesis is valuable for the manufacture of ZK_type worm. In addition,the errors of the AutoCAD design system was studied.which was pivotal to the control of machining simulation precision.
