It plays a role in matching speed and transmitting torque between the prime mover and working machine or the implementing agency. This paper is about the design of a twocylinder gear reducer, including the design of gear, the design of shaft and the strength check of them. With threedimensional modeling and assembly by Pro/E, the results have the most direct manifestation. By the initial establishment of this parametric design system, the program can devise a reducer, shorting the design cycle, saving design costs, and subjoining the accuracy of it. It is the great significance to improve product quality.
