Abstract

En los últimos tiempos los materiales plásticos han tenido una proliferación en todos los campos de la Industria Mecánica,
debido esencialmente a su bajo costo y a las mejoras de las propiedades mecánicas que se han ido logrando. En el caso
particular de las transmisiones por engranajes existe una gran cantidad de estos materiales que pueden ser usados y de
hecho se utilizan para la fabricación de ruedas dentadas de características muy disímiles. En la literatura científica existe
muy poca información disponible sobre las fallas de engranajes plásticos, métodos de calculo a resistencia y posibles
materiales a emplear con sus respectivas propiedades mecánicas. Inclusive este tema no se aborda en los currículos de
estudio tradicionales en Ibero-América. Queda mucho por discutir aun acerca del empleo de las correcciones del dentado en
estas ruedas dentadas plásticas. En el presente trabajo se hace un análisis de los materiales, características, estudio de las
fallas principales, métodos de calculo y ejemplos de aplicación de los engranajes plásticos.


Palabras claves: Plásticos, engranes, perfil dentado.

Abstract.
Recently the use of plastic materials has been growing up due to their low cost and the improvements achieved on their
mechanical properties. In the particular case of gear transmissions there are great quantities of polymers that can be used
for gears. Plastic gears are powerful means of cutting drive cost, weight, noise, and wear. Plastic gears also open new
opportunities for smaller and more efficient transmissions. There is few information in Scientific literature about plastic
gears failures, designing methods and materials. Most engineering reference books are desicated to steel gears but there are
remarkably silent about plastic gears. Design methods for plastic gears and gear trains must be modernized, because much
of the information available is derived from research in metal gears. Main failures of plastic gears, calculation methods and
the use of modification profiles among other considerations are showed in this paper.


Key words: Plastics, gears, design.
