Todays computer technology in mechanical design and manufacturing plays an important role in variety of design software, all aspects of mechanical design has been widely used. This topic in computer aided design manufacture theory, under the guidance of a new kind of double cycloidal steel ball reducer is studied. This new type reducer and researches have been compared the gear reducer, has the following characteristics: (1) transmission range, the biggest can amount to several thousand. If make multistage speed reducer, criterion more show the advantages of this gear reducer. (2) simple structure, small volume, light weight. (3) mechanical high efficiency. With the rolling friction is substituted for sliding friction, reduce the friction and improve the transmission efficiency. This is as many other reducer. The paper introduced the main contents include: double cycloidal steel ball planetary gear reducer structure characteristics and working principle, selecting a group of design parameters for the detailed design, analysis the influence of gear reducer. Performance parameters According to the speed reducer is calculated and performance parameters of CAD software draw gear reducer and parts drawing assembly drawings. This research results for double
