This paper presents a method for complete shaking force and shaking moment balancing of 3 types of four-bar linkages only with revolute pairs due to rotary inertia but without external loads. The method is a combination of mass redistribution and addition of two kinds of inertia counterweights, which are the geared inertia counterweights and the planetary-gear-train inertia counterweight. The design equations for complete force and moment balancing of crank-rocker and double crank mechanisms are given. The method is illustrated by a numerical example and results produced are better than that of GaoFeng’s method.
