Research Of Worm-bevel Gear Reducer Virtual Assembly

The Worm-bevel gear Reducer is a general slowdown in a common unit, It’s used to pass between the cross-axis movement and power, Usually staggered two-axis angle of90°. Generally, In the worm drive, the worm is active pieces. Characterized by overall size is small, transmission ratio, smooth transmission, low noise, but low efficiency. As the worm material more commonly used bronze and other precious metals manufacturing, so it’s high cost. When the drive is larger than required, we can use worm-bevel gear Reducer. However, due to worm shape is more complex surfaces, application of traditional methods of its three-dimensional drawing, not only the process cumbersome, inefficient, and prone to error.This subject around the problem of worm-bevel gear Reducer design parameters and virtual assembly, then make a depth study of the worm design parameters and virtual assembly.The subject based on a powerful three-dimensional software UG as a development platform, and make a depth study of the parameters of the design and method of secondary development, it used secondary development tools of UG,such as UG/Open Grip achieve Worm3D parametric modeling. It used UG/Open API, C++and other technical development and design of the worm’s parametric design system. Upon completion of the three-dimensional model of worm, you can create three-dimensional model of the other parts, and complete virtual Reducer assembly, the gear transmission for interference analysis. Then, we put three-dimensional model of the Reducer what created in the UG into3Ds Max rendering optimized, and finally developed virtual assembly system of reducer based on virtools platform.In the software of UG, we achieve the parameters of worm design, so you can quickly and accurately generate the required three-dimensional model, and completed all parts of the modeling and Reducer assembly. And in software of virtools to worm-bevel gear Reducer for the study, in-depth study of the "removable can be installed" as the basic principle to achieve a virtual fixture assembly. Then, we using the switching of the view, we make the assembly process is simple and clear.
