This paper analyzed the vibrational features of a gear coupling with misaligment fault by means of the analysis of the forces and motions of the coupling,including two and three dimensional analysis.From the analysis,the angle between the axes of the annular gear and outer profile of the coupling in its steady mesh was derived,and a general method for determining the angle was obtained by using an equilibrium of the forces and couples exerting on the annular gear,from which the vibrational features of the coupling could be revealed.
