Abstract

UN MECANISMO DE RODADURA PARA MATERIAL MOVIL ELECTRICO QUE TIENE UN MOTOR DE TRACCION CUYO ARBOL DE ROTOR ESTA PREVISTO PARA TENER AL MENOS UNA PARTE, EN LA QUE EL COJINETE HACE CONTACTO, HECHA DE UN MATERIAL ELECTRICAMENTE AISLANTE. EL MATERIAL ELECTRICAMENTE AISLANTE IMPIDE LA EROSION DEL COJINETE DEL MOTOR DE TRACCION DEBIDA A LA CORRIENTE ELECTRICA ALIMENTADA A LOS EJES.A ROLLING MECHANISM FOR ELECTRIC MOBILE EQUIPMENT THAT HAS A TRACTION MOTOR WHOSE ROTOR TREE IS INTENDED TO HAVE AT LEAST ONE PART, IN WHICH THE BEARING CONTACTS, MADE OF ELECTRICALLY INSULATING MATERIAL. THE ELECTRICALLY INSULATING MATERIAL PREVENTS EROSION OF THE TRACTION MOTOR BEARING DUE TO THE ELECTRIC CURRENT SUPPLIED TO THE AXLES.
