Abstract

LA INVENCION SE REFIERE A UN SISTEMA DE ALARMA ADECUADO PARA SU USO EN EL AVISO DEL SOBRECALENTAMIENTO DE COJINETES GIRATORIOS (4) QUE TIENEN UNA PRIMERA Y UNA SEGUNDA PARTES. EL SISTEMA DE ALARMA COMPRENDE UN MEDIO GENERADOR DE SEÑALES DE ALARMA QUE TIENE UN ELEMENTO DE AJUSTE TERMICAMENTE ACTIVADO (8) SOBRE UNA PRIMERA PARTE DEL COJINETE O CUERPO (6) CONECTADO AL MISMO. EL ELEMENTO SE ENCUENTRA EN CONEXION TERMICA CON EL COJINETE (4) Y ESTA FORMADO Y DISPUESTO DE MANERA QUE SEA IMPULSADO DESDE UNA PRIMERA POSICION CONTRAIDA A UNA SEGUNDA POSICION DE ALARMA DESPLEGADA DESPUES DE QUE SE ALCANCE UNA TEMPERATURA PREDETERMINADA. EN LA POSICION DE ALARMA EL ELEMENTO (8) SE PONE EN CONTACTO CON UNA PARTE (12) DE LA SEGUNDA PARTE DEL COJINETE DE MANERA QUE SE PRODUZCA UNA SEÑAL DE ALARMA DISTINTIVA INDICADORA DE QUE DICHO COJINETE HA EXCEDIDO UNA TEMPERATURA PREDETERMINADA.
