To improve the calculation accuracy of the wrap angles, which are key parameters for the estimation of the maximum torque of the belt system, the steady configuration of the belt was researched. The governing equations and boundary conditions of the belt steady configuration were proposed and the following factors were considered in the model: the centrifugal force, the bending stiffness and the gravity of the belt. The belt steady configuration can be solved through a proposed iteration method based on the built model. The results show the gravity of the belt plays an important role on the belt steady configuration. The wrap angles calculated from the steady configuration are much less than that from the traditional geometric analysis. Thus the maximum torque of the belt system could be overestimated in the traditional belt design theory. It is necessary to calculate the wrap angles by solving the belt steady configuration, especially for the long center distance, high speed belt system.
