Utilización de Sistemas Basados en Reglas y en Casos para dise？ar transmisiones por tornillo sinfín

nowadays artificial intelligence techniques are applied successfully to different engineering problems, especially the "knowledge based systems". among them the most common are the "frame based systems", "rules based systems", "case based systems" and "hybrid systems". the "case based systems" (cbs) analyze solved problems in an application domain and by means of a process of adaptation; they find the solution to a new problem. these systems can be used successfully for the design of gears, particularly for designing worm gears; nevertheless it constitutes a field of the applications of artificial intelligence even unexplored. a comparison of the use of "rules based system" and "cases based system" for worm gear design is made at this paper. it is also showed the results of applying the "rule based systems to a particular design of a worm gear transmission
