Abstract

UNA TALADRADORA DE MARTILLO PUEDE AJUSTARSE PARA OPERACION EN UN MODO DE MARTILLO O EN UN MODO DE TALADRO A TRAVES DE UN SELECTOR DE MODO 41. EN EL MODO DE TALADRO, UN EJE DE SALIDA 25 ESTA BLOQUEADO EN UNA POSICION DESVIADA HACIA ADELANTE Y ES ACCIONADA DE FORMA GIRATORIA A TRAVES DE ENGRANAJES CILINDRICOS 29, 31. EN EL MODO DE TALADRO DE MARTILLO, UNA BROCA DE SALIDA 25 ES ACCIONADA GIRATORIAMENTE POR ENGRANAJES CILINDRICOS 29, 31 Y ES INTERCAMBIADA AXIALMENTE POR UN MARTILLO DE EMBRAGUE 55. UNA PLACA DE EMBRAGUE DE SALIDA 57 DEL EMBRAGUE 55 ESTA AXIALMENTE Y GIRATORIAMENTE FIJADA A LA BROCA 25 Y TIENE UN PRIMER SISTEMA DENTADO ANULAR 63 EN LA PARTE POSTERIOR 61. UNA PLACA DE EMBRAGUE DE ENTRADA 59 DEL EMBRAGUE 555 ESTA AXIALMENTE Y NO GIRATORIAMENTE FIJADA EN EL ALOJAMIENTO DE LA HERRAMIENTA 15 Y TIENE UN SEGUNDO SISTEMA DENTADO ANULAR 67 EN UNA PARTE DELANTERA INCLINADA HACIA ADELANTE 65. LOS SISTEMAS DENTADOS 63, 67 SON ENGRANABLES EN EL MODO DE MARTILLO. UNA PLACA DE EMBRAGUE DE SALIDA 57 ES DESPLAZABLE CUANDO SE UTILIZA EN EL MODO DE MARTILLO PARA COLOCAR LA PARTE POSTERIOR 61 GENERALMENTE PARALELA A LA PARTE DELANTERA 65. LA INCLINACION HACIA ADELANTE DE LA PARTE FRONTAL DEL EMBRAGUE DE ENTRADA 65 COMPENSA EL MOVIMIENTO DE LA PARTE POSTERIOR DEL EMBRAGUE DE SALIDA 61 DESDE UNA POSICION DE NO CARGA A UNA POSICION DE CARGA PARA QUE PARTES 65, 61 ESTEN GENERALMENTE PARALELAS CUANDO SE UTILICEN. ASEGURANDO EL PARALELISMO DE LAS PARTES DEL EMBRAGUE 65, 61, CUANDO SE UTILICE, EL EMBRAGUE 55 TIENE UNA DURACION SIGNIFICATIVAMENTE AUMENTADA.
