The structure and transmission principle of Filtering Gear Reducer （FGR） with small tooth number difference was introduced. Based on the geometry size related differential model, the transmission ratio formula of the reducer with considering the component eccentricity including eccentric shaft, dual gear and fixed gear was de- rived, and transmission error curves were obtained by applying the numerical solution for differential equations. The transmission error test on the reducer was carried out. The method was used for the eccentric transmission calcula- tion in this paper was verified by the test results. Meanwhile, the test results illuminated that the eccentric error study played an important role in the transmission error study of filtering gear reducer.
