La huella de contacto entre flancos como indicador de la precisión de la transmisión por engranaje de tornillo sinfín. // The tooth contact pattern as indicator of the cylindrical wormgearing precision.
Abstract
El objetivo de esta investigación es la creación de un procedimiento que permita evaluar el grado de precisión de la
transmisión por tornillo sinfín, teniendo en cuenta los errores de fabricación y montaje propios de cada tecnología de
elaboración. Se utilizó un método teórico, que combinado con las mediciones físicas de la huella de contacto, dieron lugar a
un procedimiento que se fundamenta en el empleo de nomogramas que contienen los parámetros del contacto entre flancos.
Se aprecia que el procesamiento de las imágenes digitales de la huella, permite establecer determinadas características de
calidad del par engranado.
Palabras claves: Engranaje de tornillo sinfín, grado de precisión, huella de contacto, montaje.

Abstract:
The objective of this investigation is the establishment of a procedure to evaluate the degree of accuracy of the worm
gear transmission, taking into account the manufacturing errors and assembly. A theoretical method was used and
combined with the physical measurement of tooth contact pattern, giving as result a procedure focused on the use of
nomograms related to contact parameters between faces. It can be appreciated that digital image processing of tooth
contact pattern give the possibility of state gear quality features
Key words: Worm gear, accuracy, tooth contact patter.
