Abstract

UNA TRANSMISION PROGRESIVAMENTE VARIABLE (16) PARA TRANSMITIR UN PAR ENTRE EL RODILLO DE ENTRADA Y EL DE SALIDA (4,6) DE UN DISPOSITIVO PRETENSOR (2) DE UNA MAQUINA PARA ENVOLVER CON PELICULAS TENSAS QUE PRETENSA DE FORMA SELECTIVA UNA PELICULA DE PLASTICO CON UN PUNTO CEDENTE, QUE SE DESPLAZA HASTA ENTRAR EN CONTACTO CON LOS RODILLOS. AL RODILLO DE ENTRADA (4) SE LE HACE ROTAR A MENOS RPM QUE EL RODILLO DE SALIDA (6) Y LA TRANSMISION (16) COMPRENDE UN TREN DE ENGRANAJES DE MULTIPLES RADIOS (22) ENTRE UN EJE DE ENTRADA (28) Y UN EJE DE SALIDA (26), EN DONDE DICHO TREN DE ENGRANAJES (22) SE ENCUENTRA COLOCADO EN UN RECEPTACULO (18) Y UN DISPOSITIVO (24) ENGANCHA EL EJE DE ENTRADA (28) AL Y LO DESENGANCHA DEL TREN DE ENGRANAJES. LOS EJES DE ENTRADA Y DE SALIDA (28, 26) DEL TREN DE ENGRANAJES SON COAXIALES. EL DISPOSITIVO DE ACOPLAMIENTO ES UN EMBRAGUE DE RUEDA LIBRE (2) QUE SE QUEDA EN LA POSICION ACOPLADA CUANDO SE IMPARTE UN PAR AL RODILLO DE ENTRADA (4), DEBIDO A LA TENSION DE LA PELICULAENTRE LOS RODILLO, DESDE EL RODILLO DE SALIDA (6) Y EL EMBRAGUE (20) SE LIBERA EN AUSENCIA DE DICHO PAR.A PROGRESSIVELY VARIABLE TRANSMISSION (16) TO TRANSMIT A TORQUE BETWEEN THE INPUT ROLLER AND THE OUTLET (4,6) OF A PRETENSIONING DEVICE (2) OF A MACHINE TO WRAP WITH TENSIVE FILMS TO SELECTIVELY PRETEND A FILM WITH PLASTIC A GIVING POINT, WHICH MOVES UNTIL CONTACTING THE ROLLERS. THE INLET ROLLER (4) IS ROTATED AT LESS RPM THAN THE OUTLET ROLLER (6) AND THE TRANSMISSION (16) COMPRISES A MULTIPLE-SPOKE GEAR TRAIN (22) BETWEEN AN INPUT AXLE (28) AND A SHAFT DEPARTURE (26), WHERE SUCH GEAR TRAIN (22) IS LOCATED IN A RECEPTACLE (18) AND A DEVICE (24) HITCHES THE ENTRY AXLE (28) TO AND DISENGAGES IT FROM THE GEAR TRAIN. THE INPUT AND OUTPUT SHAFTS (28, 26) OF THE GEAR TRAIN ARE COAXIAL. THE COUPLING DEVICE IS A FREEWHEEL CLUTCH (2) THAT REMAINS IN THE COUPLED POSITION WHEN A TORQUE IS GIVEN TO THE ENTRY ROLLER (4), DUE TO THE TENSION OF THE FILM BETWEEN THE ROLLER (6 ) AND THE CLUTCH (20) IS RELEASED IN THE ABSENCE OF SUCH PAR.
