To improve the quality and precision of the conveying equipment, in addition to strictly control the production craft, more important is to improve the design quality and the design efficiency. In this study, Solid Edge ST4 3 d modeling technology will be proposed to be used in synchronous roller conveyor design. A double chain transmission roller conveyor will be designed. In the process of design, synchronous modeling, parallel design, cooperative modeling technique and Top-down Assembly Modeling technology are combined with during the design. Modular design train of thought is used to consider the overall structure of design scheme. Design of roller conveyor will be divided into different design module to consider, the aim is to promote the standardization of product design. The key point in this paper is focused on the parametric design, top-down assembly modeling technology, synchronous modeling technology [1] in roller conveyor design. Meanwhile exploring roller conveyor and other general transportation equipment design process of standardization implementation is another main work. The results show that the application of the technology can reduce design error and design iterative process, thus greatly improve the design efficiency and engineer the design of the product quality.
