The paper mainly aims at the common problems existing in driving components, especially in harmonic reducer, RV reduction gear etc., which are used in mechatronic accoutrement of engineering fields, e.g. robots, automation, advanced manufacturing at home and abroad. The paper cared about the key problems that flexspline of harmonic reducer is easy to endurance failure while continuous deflection. The paper put forward a new high performance filter transmission mechanism with high reliability, high precision, long life, large torque, lower energy consumption, small volume and lower weight, especial about the innovation design method of high performance filter transmission mechanism. The new transmission mechanism is composed of eccentric sleeve, inner meshed planet gear pair of small teeth difference, filter spline pair, three ways thrust bearing and so on. Rolling pair can filter high rotational speed of electric engine. The filter spline can filter secondary harmonics and deliver the movement to the output device smoothly. Three ways thrust bearing assure identical rotation between input interface and output interface while it limits the movement in other five way freedom. The paper has designed the eccentricity and tooth outline, made numerical simulation of the meshing process with pressure angle of 30 and 40, calculated the transmission efficiency, checken the intensity of wheels, operated comprehensive tests about transmission precision, rigidity and backlash, transmission efficiency, and so on.
