Abstract

SE MONTAN ROTORES PRINCIPAL Y DE ENTRADA DE ENGRANAMIENTO HELICOIDAL (1, 2) PARA GIRAR ALREDEDOR DE SUS EJES EN RESPECTIVOS ORIFICIOS INTERSECTANTES EN UN ALOJAMIENTO. LOS PERFILES DE LOS ROTORES SEGUN SE VEN EN LA SECCION DE CORTE SON GENERADOS POR LA MISMA FORMACION DE LA SECCION DENTADA. LOS FLANCOS DE ALTA PRESION DE LOS LOBULOS DEL ROTOR PRINCIPAL (1) Y LAS RANURAS DEL ROTOR DE ENTRADA (2) SON GENERADOS AMBOS POR UNA PARTE PREFERIBLEMENTE CICLOIDAL (GHA) DE LA SECCION DENTADA R.
