CABELLO-ULLOA, Mario Javier et al. An equivalent mechanism for the kinetic and dynamic analysis of the sugar cane mill gears. Ingeniería Mecánica [online]. 2011, vol.14, n.3, pp. 209-220. ISSN 1815-5944.

Equivalent mechanism is proposed for modeling sugar cane mills gears, which allows to take into account the shape of the tooth profile formed by circular arcs and the variation of the distance between centers for operation. Applying the graph-analytical method to the proposed model is obtained a function to define the instantaneous angular position of the sugar cane mill gear in relation with the instantaneous angular position of driver gear and the center distance of gears. General equations for the velocity and acceleration for any type of gear tooth profile with variable distance between centers are proposed through parametric method. Plotted these parameters for real sugar cane mill gear and it is concluded that the instantaneous speed ratio is variable and the profile shape produced accelerations.
