【Abstract】 Taking the geometric backlash of RV reducer as the research object, the mathematical model of geometric deviation including the manufacturing and assembly errors of rotation pairs and meshing pairs is derived. The auxiliary design software is written for calculation, and the sensitivity analysis is carried out. According to the calculation results, the main factors affecting the geometric deviation of RV reducer are found. By using the method of orthogonal test, the model of robust design optimization is established, and the optimal combination of the influencing factors of the backslip of RV reducer is determined. The backslip size of RV reducer is effectively reduced, and the design requirements are met.更多还原
