Abstract

UNA MAQUINA HERRAMIENTA MUESTRA MULTIPLES BRAZOS (3) TELESCOPICOS, CADA UNO DE ELLOS ELABORADO A BASE DE UN TUBO INTERIOR Y UN TUBO EXTERIOR (1,2). CADA BRAZO (3) TELESCOPICO ESTA ARTICULADO EN UN EXTREMO A UNA ESTRUCTURA (4) Y EN EL OTRO A UN RECEPTOR (5) DE HERRAMIENTA. VARIAS CAVIDADES (7) ESTAN DISTRIBUIDAS A LO LARGO DE LA CIRCUNFERENCIA DEL TUBO (1) EXTERNO, EN DONDE ESTAN LOCALIZADAS UNIDADES (8) DE BOLA CIRCULANTES. CADA UNA DE ESTAS UNIDADES (8) CONSISTE EN UN CUERPO (9) SOPORTE CON UNA RANURA (10) DE BOLA SINFIN. CADA RANURA (10) DE BOLA SINFIN TIENE UNA SECCION (11) DE CARGA Y UNA SECCION (12) DE REALIMENTACION DE APOYO NO CARGADA ASOCIADA. EL TUBO (2) INTERIOR TIENE RANURAS (13) DE BOLAS. LAS BOLAS (4) RUEDAN A LO LARGO DE LAS RANURAS (10,13) DE BOLA DEL TUBO (2) INTERIOR Y DEL CUERPO (9) SOPORTE, SIENDO DIRIGIDAS LAS BOLAS (14) DESDE LA SECCION (11) DE CARGA A LA SECCION (12) DE REALIMENTACION.
