Following with it, knowledge reuse has e an important means to enhance the speed of product exploit ation , respond to the requirement of market fleetly and make maximum use of the resource. Reducer as one of the ponents of mechanical and electrical products, the traditional reducer design usually adopts a single design pattern, the design cycle is long and the efficiency is low, competition in the market is in inferior position apparently, in the past, the study is specific for a particular type, the applicable range is relatively narrow. In order pensate for this design method, improving the petition ability of the product, we introduce a method of rapid design, key research items are as follows: (1) According to reducer design theory and method, the functions and overall structure of reducer quick design system has been determined. (2) The research of design means based on knowledge has been carried out. By analyzing the characteristics of reducer design knowledge, this paper selects a kind of mixed representation, which uses object-oriented representation as frame and synthesize database representation rule representation and process representation. (3) This paper researches how to build the knowledge base in the relational database. T
