Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA EL ENDURECIMIENTO POR INDUCCION DE SUPERFICIES ONDULADAS DE UNAS PIEZAS DE HERRAMIENTA COMO EL ENGRANAJE DE UNAS RUEDAS DE ENGRANAJE O DE CADENA. SE CONSIGUE UNA FORMACION DE DUREZA DISTRIBUIDA SIMILARMENTE POR EL ENGRANAJE Y CONTROLADA PROFUNDAMENTE, YA QUE LA SUPERFICIE DE LA PIEZA DE HERRAMIENTA A ENDURECERSE SE EXPLORA POR LA BOBINA (12) DE CALENTAMIENTO POR INDUCCION, MIENTRAS LA PIEZA HERRAMIENTA SE HACE PASAR POR LA BOBINA (12) DE CALENTAMIENTO POR INDUCCION. SE CARACTERIZA EL PROCEDIMIENTO PORQUE UN CALENTAMIENTO FINAL EXPLORANDO LA PIEZA HERRAMIENTA OBEDECE A UN CALENTAMIENTO PREVIO EXPLORANDO LA PIEZA HERRAMIENTA POR LO QUE PUEDEN REALIZARSE LOS CALENTAMIENTOS PREVIO Y FINAL CON VELOCIDADES CONTROLADAS Y DIFERENTES. LA EXPLORACION REPETIDA DE LAS HERRAMIENTAS (W) POR UNA BOBINA (12) INDUCTIVA PERMITE EL CALENTAMIENTO PREVIO Y EL CALENTAMIENTO FINAL DE LA PIEZA HERRAMIENTA QUE NO PUEDE REALIZARSE DE FORMA INMEDIATA Y EN DIRECCION AXIAL POR BOBINAS INDUCTORAS SEPARADAS COMO ES EL CASO DE RUEDAS DE ENGRANAJES PLANETARIAS CON ANILLO INFERIOR QUE PRESENTA UN EXTREMO (12) CERRADO O COMO ES EL CASO DE RUEDAS DENTADAS EN ESTRELLA QUE PRESENTAN UN ESCALON SALIENTE RADIAL O UN FLANCO SALIENTE POR EL DENTADO CILINDRICO.
