Virtual Assembly and Kinematic Simulation of Micro-segment Helical Gear Based on CATIA

Micro-segment heLical gear is a new gear, and the tooth is made up of two "convex - concave" parts, which are different from the traditional in volute gear. In order to further understand and study the characteristics of this gear, the contour calculation about a pair of gears with given parameters is given in the first, and then the 3D models are set up with CATIA. Then the virtual assembly is finished using this software. At last, the kinematic simulation is suppLied by the "DMU (an compositive module in CATIA )" to analyze the motion characteristics. The study here is important to enhance design level and theoretical analysis capacity of the gear, and to speed up the appLication process at the same time.
