Abstract

DISPOSITIVO DETECTOR DE DESGASTE DE ESCOBILLAS PARA MAQUINAS DINAMOELECTRICAS.COMPRENDE: A) UN RESORTE DE BALLESTA ELECTRICAMENTE CONDUCTIVO, CON UNO DE SUS EXTREMOS (7A) FIJADOS A UN PRIMER MIEMBRO DIELECTRICO (8) Y EL OTRO EXTREMO (7B) LIBRE PARA MOVERSE. EL PRIMER MIEMBRO ES UTIL PARA AISLAR EL RESORTE DE BALLESTA RESPECTO AL SOPORTE DEL MUELLE (5) EMPUJADOR DE ESCOBILLA; B) UN SEGUNDO MIEMBRO DIELECTRICO (10) ASEGURADO A UNA PORCION DEL RESORTE (7) DE BALLESTA ENTRE LOS EXTREMOS. ESTA DISPUESTO PARA ENGRANAR CON UNA PORCION DEL RESORTE (7) DE BALLESTA ENTRE LOSEXTREMOS. ESTA DISPUESTO PARA ENGRANAR CON UNA PORCION NO ENROLLADA DEL MUELLE EMPUJADOR DE ESCOBILLA (4), CUANDO ESTE SE EXTIENDE CON UNA LONGITUD PREDETERMINADA; C) EL RESORTE DE BALLESTA (7) ES EFICAZ PARA MOVER SU EXTREMO LIBRE HACIA UN ENGRANAJE ELECTRICAMENTE CONDUCTIVO CON EL SOPORTE DE MUELLE (5); D) SISTEMAS TERMINALES (11) PARA CONECTAR ELECTRICAMENTE EL CIRCUITO INDICADOR DE DESGASTE (6) DE ESCOBILLA AL RESORTE DE BALLESTA (7); EL CIRCUITO PUEDE SER DESCONECTADO ELECTRICAMENTE DEL SOPORTE DE MUELLE (5) Y ESTE CIRCUITO ES ELECTRICAMENTE ENERGIZADO A TRAVESDEL SOPORTE DE BALLESTA (7).
