The statistic model of ring reducer is established, and its statistic analysis of key components, just as bears of eccentricity shafts、inner teeth ring plate are analyzed and the force property function of eccentricity shaft is gotten. After detail analysis for contact property of double-ring reducer, a simple and accurate method for calculating the efficiency of engagement is extraction, it is useful to raise the designing efficiency of double-ring reducer. The structural balance and the instant phase margin of two inner teeth plate gears are discussed and the contact ratio、the equation for calculating max force of eccentricity shafts are concluded and the force changing curve of eccentricity shafts are drawn. Finally, we learn method of I-DEAS software about 3D entity model, and apply software I-DEAS to establish 3D entity model、virtual assembly and movement simulation of double-ring reducer. After above analysis, these theories for designing and study of double-ring reducer are provided in our research.
