Abstract: Proposes the condition to satisfy the magnitude of modification of cycloidal gear used in robot. Based on it, proposes the optimum mathematics model of modification of cycloidal gear in order to achieve the main qualifications of high kinematic accuracy, little backlash, high-load capacity, high rigidity, and high transmission efficiency of RV reducer used in robot, It is proved that the new optimized tooth-profile of cycloidal gear is correct and practical by sample machine test.

Key words: Cycloidal gear, Modification, Optimizing, RV reducer
