Abstract
UNA JUNTA MECANICA PARTIDA (10), PARA MONTAR EN UNA CARCASA ESTACIONARIA (14) QUE CONTIENE UN ARBOL ROTATIVO (12), INCLUYE UN PRIMERO (20) Y UN SEGUNDO (30) CONJUNTOS DE ANILLOS DE JUNTA, POR LO MENOS UN ELEMENTO DE DESVIO ELASTICO Y POR LO MENOS UN ELEMENTO DE DESVIO AXIAL. EL PRIMERO Y EL SEGUNDO CONJUNTOS DE ANILLOS DE JUNTA INCLUYEN CADA UNO UN ANILLO DE JUNTA QUE TIENE DOS SEGMENTOS (22,32) QUE ESTAN SOPORTADOS ELASTICAMENTE EN LA JUNTA. LOS SEGMENTOS (22,32) TIENEN UNA SUPERFICIE EXTERIOR Y UN PAR DE CARAS DE JUNTA DEL SEGMENTO (21,31) DISPUESTAS EN LOS EXTREMOS OPUESTOS DE LOS SEGMENTOS (22,32). EL ELEMENTO DE DESVIO ELASTICO (200) ESTA DISPUESTO CONCENTRICAMENTE ALREDEDOR Y EN INTIMO CONTACTO CON LA SUPERFICIE EXTERIOR DE UNO DE LOS ANILLOS DE JUNTA, PARA APLICAR UNA PRIMERA FUERZA RADIAL HACIA EL INTERIOR QUE DESVIA LAS CARAS DE JUNTA (21,31) DE LOS SEGMENTOS DEL ANILLO DE JUNTA (22,32) EN CONTACTO DE JUNTA UNA CON OTRA. LA JUNTA MECANICA (10) INCLUYE UN PAR DE ELEMENTOS DE DESVIOELASTICOS DISPUESTOS ALREDEDOR DE CADA ANILLO DE JUNTA Y EL ELEMENTO DE DESVIO ELASTICO (132) ES PREFERIBLEMENTE UN MIEMBRO ELASTOMERO. EL ELEMENTO DE DESVIO AXIAL (200) ESTA ASOCIADO CON AL MENOS UN ANILLO DE JUNTA (33) PARA GENERAR Y APLICAR EN COOPERACION CON EL MIEMBRO ELASTOMERO (132) UNA SEGUNDA FUERZA RADIAL HACIA EL INTERIOR; LA SEGUNDA FUERZA ACTUA PARA DESVIAR LAS CARAS DE JUNTA DEL SEGMENTO (21,31) UNIDAS CUANDO LA JUNTA MECANICA (10) ES EXPUESTA A UNA CONDICION DE PRESION SELECCIONADA. EL ELEMENTO DE DESVIO AXIAL (200) ES UN CONTRAFUERTE, FORMADO INTEGRALMENTE CON LOS SEGMENTOS (22,23) DE LOS DOS ANILLOS DE JUNTA QUE TIENE UNA SUPERFICIE EXTERIOR INCLINADA RADIALMENTE HACIA AFUERA. CUANDO LA JUNTA MECANICA (10) ES EXPUESTA A UNA CONDICION DE PRESION SELECCIONADA, EL MIEMBRO ELASTOMERO (132) ES DISPUESTO EN CONTACTO INTIMO CON EL CONTRAFUERTE (192) Y APLICA UNA FUERZA AXIAL AL MISMO. EL CONTRAFUERTE (192) TRANSFORMA LA FUERZA AXIAL EN UN COMPONENTE DE FUERZA AXIAL Y EN UN SEGUNDOCOMPONENTE DE FUERZA RADIAL HACIA EL INTERIOR. ESTE SEGUNDO COMPONENTE RADIAL HACIA EL INTERIOR TAMBIEN ACTUA PARA DESVIAR LAS CARAS DE JUNTA (21,31) DE LOS SEGMENTOS DE ANILLO DE JUNTA (22,32) EN CONTACTO DE JUNTA UNO CON OTRO. LA JUNTA INCLUYE ADEMAS CARCASAS (80,82) DE TORNILLO FORMADAS INTEGRALMENTE QUE HAN FORMADO UNA ABERTURA DE RECEPCION-SUJECION (84). LA ABERTURA (84) TIENE UNA PARTE DE PEQUEÑO DIAMETRO ROSCADA INTERIORMENTE Y UNA PARTE NO ROSCADA INTERIORMENTE DE MAYOR DIAMETRO. LA ABERTURA (84) TIENE UN TORNILLO (90) CON UNA CABEZA ROSCADA (96) Y UN VASTAGO (92). EL VASTAGO (92) TIENE UN EXTREMO DISTAL DE MAYOR DIAMETRO CON ROSCA INTERIOR Y UN EXTREMO PROXIMAL DE MENOR DIAMETRO. EL TORNILLO (90) CUANDO ESTA MONTADO DENTRO DE LA ABERTURA, ES MANTENIDO EN ELLA POSITIVAMENTE. LA JUNTA (10) INCLUYE ADEMAS UN MECANISMO DE CENTRADO. EN UNA REALIZACION, EL MECANISMO DE CENTRADO ES UNA ABRAZADERA DE CENTRADO (240), ASENTADA DENTRO DE UN AGUJERO TRANSVERSAL FORMADO POR LAS CARCASAS DE TORNILLOS (80,82), QUE TIENE UN MANGO (248) Y UN PAR DE SEGMENTOS FLEXIBLES ALARGADOS (250,252). EN OTRA REALIZACION, EL MECANISMO DE CENTRADO SE COMPONE DE UN NUMERO DE ESPACIADORES (240) DISPUESTOS EN UNA PARED EXTERIOR DEL CONJUNTO SOPORTE.
