For the sake of improving design efficiency and intelligence, a design method of the second order cylindrical gear reducer based on CBR is presented in the paper. Firstly, the paper describes the principle of CBR. Secondly, three key technologies of CBR are studied and the corresponding methods are proposed, which are the object-oriented knowledge representation method, a retrieval method combining the nearest neighbor with the induction indexing, and case adaptation algorithm combining the revision based on rule with artificial revision. Meanwhile, for the sake of improving credibility of case retrieval, the paper presents a kind of new method determining the weights of characteristics and a similarity formula, which is a combinatorial weighting method with the analytic hierarchy process (AHP) and roughness set theory. Lastly, according to the above results, a design system of the second order cylindrical gear reducer based on CBR is developed by VC++、UG and Access.
