Abstract

EN UNA INCORPORACION, UNA JUNTA DE CIERRE CON BOLA DE OSCILACION O APARATO MANEJANDO UNA TRAMA INCLUYE UN HUSO ROTATORIO (12) TENIENDO UNA ENTRADA LA CUAL ACEPTA UNA TRAMA (10) TUBULAR. UN RODAMIENTO(14) DE CIERRE SE MONTA EN LA ENTRADA. UNA PLURALIDAD DE RODAMIENTOS (22,24,26,28,30,32, 34,36) SE DISPONEN CIRCUNFERENCIALMENTE ALREDEDOR DE EL RODAMIENTO DE CIERRE (14) Y LOS EJES DE ROTACION DE ESTOS RODAMIENTOS (22,24,26,28,30,32 34,36) SON PARALELOS A LA LINEA CENTRAL DEL HUSO (10) TUBULAR. UNA BARRA DE GIRO (44) ESTA DISPUESTA EN EL INTERIOR DEL HUSO (12) Y GIRA LA TRAMA (62) PLANA MOVIENDO EL RODAMIENTO DE CIERRE 90 GRADOS DE UN EXTREMO A A OTRO Y ALIMENTA LA TRAMA HORIZONTAL HACIA UN RODAMIENTO INICIAL DE LA PLURALIDAD DE RODAMIENTOS (22,24,26,28,30,32,34) DISPUESTOS EN LA PERIFERIA DEL HUSO (12). LA TRAMA MOVIL (62) SIEMPRE PASA SOBRE ESTE PRIMER RODAMIENTO. ROTANDO EL HUSO (12) DE FORMA OSCILATORIA ALREDEDOR DEL EJE CENTRAL DE LA TRAMA (10) TUBULAR, SE DESPLAZA HORIZONTALMENTE, LA TRAMA (62) PLANA SE ARROLLA Y DESENROLLA ALREDEDOR DE LA PERIFERIA EXTERIOR DEL HUSO (12) Y SE ACOPLA A UN RODAMIENTO (68) HOLGAZAN FIJO.
