DECOMPOSITION OF PLANAR
GEARED LINKAGE MECHANISMS*
Abstract: A new approach for decomposing the planar geared linkage mechanisms (GLM) into a series of sequential independent basic simple links and dyad link groups is presented, which can be realized in a computer automatically. According to the tricolor graph, which is introduced to describe the topological relationship between the kinematic pairs and the links in a GLM,
the criteria and procedure of GLMs’ structure decomposition by the theory of type transformation are established, which make the structure decomposing procedures of GLMs and planar linkage mechanisms (PLM) unified. Finally, the examples of structure decomposition are given. The research serves as the basis for establishing the general method for the kinematic analysis of GLMs.
