Abstract
TUBO DE RAYOS X CON ANODO GIRATORIO ACCIONADO POR MOTOR Y SOPORTADO POR UN SISTEMA DE COJINETES. EL SISTEMA DE COJINETES COMPRENDE UN COJINETE MAGNETICO AXIAL Y UN COJINETE DE MANGUITO RADIAL, EN CUYO FUNCIONAMIENTO LAS CARAS SOPORTANTES METALICAS DEL COJINETE DE MANGUITO MUTUAMENTE COOPERANTES ESTAN SEPARADAS POR UNA CAPA LIQUIDA QUE MOJA LAS CARAS SOPORTANTES, QUE CONSISTE EN UN METAL O UNA ALEACION METALICA CUYA PRESION DE VAPOR A 300 GRADOS ESTA POR DEBAJO DE 10 ELEVADO A -5 N/M.CUADRADOS, Y QUE NO ATACA A DICHAS CARAS EN GRADO SUSTANCIAL. ESTE MOJADO, FACILITA, CUANDO EL COJINETE ESTA CARGADO, QUE LAS CARAS COOPERANTES ESTEN SEPARADAS, EVITANDO EL AGARROTAMIENTO. USADO EN APARATOS DE DIAGNOSIS MEDICAS POR RAYOS X.
