[Abstract]:Parametric design of mechanical parts is one of the most important techniques in mechanical CAD technology. Parametric design can not only greatly improve the speed of product model generation and modification, but also guarantee the precision of product model. Similarity design and the development of CAD system play an important role. In order to reduce the design period of transmission parts of reducer, simplify the design work, improve the design quality and finish the task of reducer design quickly and accurately, the design period of the traditional reducer is often longer and the design work is tedious, so that the design period of the transmission parts of the reducer is reduced, and the design work is simplified. The best method is to develop the parameterized design system of reducer transmission parts by using parameterized design technology. Taking the ZDY standard reducer as an object, this paper makes a deep research on the key problems in its parametric design and modeling, and focuses on the data processing method of the design data in the process of its design and calculation. The principle and method of 3D parametric modeling are studied. The main work and achievements of the thesis are as follows: This paper discusses the structure and traditional design method of ZDY standard reducer, studies the data programming and database management method in the design process of the reducer, and interpolates the data. Curve fitting and the introduction of ADO technology into data processing have effectively solved the difficult problems of data processing in complex graphs and tables. The key problems in 3D parametric modeling of ZDY type standard reducer are studied. By using the variable table technology in Solid Edge and VB directly calling the Solid Edge modeling technology, the 3D modeling parameterization of gear transmission, shafting parts and standard parts is successfully realized. Using the technology of the same level variable and the technology of the correlation modeling, the problem of the collaborative change of the parts' dimensions in the assembly model is solved. The design and calculation flow of ZDY type standard reducer is studied. The design calculation and checking flow of gear transmission and the design calculation and checking flow of transmission shaft system are studied in detail. It provides a guarantee for the automatic acquisition of the design parameters in the parametric design of the reducer. The parametric design and modeling prototype system of ZDY standard reducer is studied with VB as development tool, based on Solid Edge 3D CAD software, combined with ADO technology and Access database technology. The whole frame of the prototype system is constructed, the interface of the prototype system is designed in detail, and the use method and the whole function of the prototype system are illustrated by the example design. The feasibility and correctness of algorithm and prototype system development.
