Abstract

La presente invención se refiere a un protector de cojinete, caracterizado dicho protector porque comprende: un rotor de forma anular, de una sola pieza, adaptado para ser llevado selladora y no rotatoriamente en la flecha, en relación circundante con ella, y un estator de forma anular, de una sola pieza, adaptado para ser montado selladora y no rotatoriamente en el alojamiento; teniendo el estator y el rotor, respectivamente, primero y segundo medios de superficie anular, formados en ellos, y dispuestas en relación concéntrica e íntimamente adyacente entre sí, a fin de definir entre ellas una trayectoria anular alargada; la trayectoria incluye un pasaje que es de muy poca anchura, que está definido entre porciones opuestas de los medios de superficie anular primero y segundo para inhibir el flujo a través de ellos; la trayectoria incluye un pasaje exterior que es extremadamente angosto, definido entre porciones opuestas de los medios de superficie anular primero y segundo, para inhibir el flujo a través de ellos; incluyendo la trayectoria un pasaje intermedio que es muy angosto y que está definido entre porciones opuestas de los medios de superficie anular primero y segundo para inhibir el flujo a través de ellos; la trayectoria incluye medios que definen un primer canal anular de dimensiones agrandadas en sección radial y axial, para recoger en él el lubricante que tienda a escapar del compartimento de cojinete; los pasajes interno e intermedio, respectivamente, comunican con lados axialmente opuestos del primer canal; el estator tiene primeros medios de abertura de escurrimiento formados en él, la trayectoria incluye medios que definen un segundo canal anular de dimensiones agrandadas en sección radial y axial, para recoger en él los contaminantes que fluyen hacia la trayectoria desde la región exterior; estando definido el segundo canal por un par radialmente opuesto de segundas ranuras en forma de canal que están formadas en el estator y el rotor, los pasajes externo e intermedio comunican, respectivamente, con los lados axialmente opuestos del segundo canal, y el estator tiene segundos medios de abertura de escurrimiento formados en una porción inferior del mismo, para dar comunicación entre una porción radialmente exterior de la segunda ranuira en forma de canal, como se definió en el estator y la región exterior.
