Modelación matemática del funcionamiento de las coronas de molinos considerando la flotación de la maza superior // An equivalent mechanism for the kinetic and dynamic analysis of the sugar cane mill gears
Abstract
Resumen
En este trabajo se propone un mecanismo equivalente para modelar el funcionamiento de las
coronas de los molinos de caña de azúcar, que permite tomar en cuenta la forma real del perfil de los
dientes trazados por arcos de círculos y la variación de la distancia entre centros durante su
funcionamiento. Aplicando el método grafo-analítico al modelo propuesto se obtiene una función
cinemática que define la posición angular instantánea de la corona conducida con dependencia de la
distancia entre ejes de las ruedas y la posición angular de la corona conductora. Aplicando métodos
paramétricos se obtienen ecuaciones para la velocidad y aceleración que son generales para
cualquier tipo de perfil de dientes en engranajes que trabajan con variación de distancia entre
centros. Finalmente se grafican estos parámetros para el funcionamiento de las coronas de un
molino real concluyéndose que estas tienen relación de transmisión instantánea variable y que por el
solo hecho de la forma del perfil se producen aceleraciones.
Palabras claves: corona de molino, engranaje, mecanismo plano, modelación, cinemática del molino.

Abstract
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.
Key words: sugar cane mill gear, gear, plane mechanism, modeling, mill kinematics
