Abstract

Un conjunto que incluye un impulsor que tiene una cara superior, una cara inferior y un agujero central dimensionado y moldeado para coincidir con un extremo de conexión de un eje. El agujero central está definido por una pluralidad de bordes laterales, donde cada uno incluye una acanaladura para cemento y unos canales dispuestos entre los bordes laterales. El extremo de conexión incluye una pluralidad de ranuras y unas acanaladuras extendidas dispuestas entre las ranuras. Cada acanaladura extendida incluye un extremo que se extiende en perpendicular a la longitud de la acanaladura extendida. En su implementación, la pluralidad de bordes laterales se comunica por fricción con la superficie externa del eje. La pluralidad de canales del impulsor está alineada con la pluralidad de acanaladuras del eje, lo que define unos pasajes que proporcionan un túnel para el arrastre de las partículas que entran en el impulsor. Las acanaladuras para cemento del impulsor están alineadas con y reciben además las acanaladuras extendidas y los extremos del eje, lo que da como resultado una conexión más resistente entre el eje y el impulsor.
