Based on the geometry size related differential model,the transmission ratio formula ofthe 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. Thetransmission 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 errorstudy played an important role in the transmission error study of filtering gear reducer.
