Correlación automatizada de parámetros geométricos mediante contornos de bloqueo en engranajes cilíndricos con contacto exterior

the aim of this work was to obtain a procedure, that when being implemented in the design software of spur and helical external gears, correlate the geometric parameters automatically by means of the blocking contours making easier the designer's work. the mathematical expressions that define the geometric limitations were transformed so that they can be used in a program that it builds the blocking contour without the designer's intervention. besides that it was settled down the sequence they should be calculated. the procedure was implemented in a calculation program obtaining an execution speed about 1 second. this way it was achieved the automatic correlation of the geometric parameters and a blocking contour construction without the designer's intervention that it shows the values of the addendum modification coefficients of the wheels that can be used.
