Abstract:In order to solve the manufacturing technology problem of Rotate Vector(RV) reducer core componentscycloid gear, the principles of grinding wheel grinding is introduced. The characteristics of the gear form grinding were analyzed. Analysis results found that the speed grinding wheel, feed speed and grinding depth were the main factors influencing the cycloid gear grinding precision. Taking the error between the theoretic grinding depth and the actual grinding depth as the research object, making the three factors in orthogonal combination, carrying out grinding experiment, and according to the analysis of experimental data, the grinding parameter combination of the minimum error is obtained, which is the basis for the subsequent cycloid gear production.
