Abstract

SISTEMA DE TUERCA Y TORNILLO ESFERICOS QUE TIENE UNA TUERCA ESFERICA (14) CON VUELTAS (16) DE ACANALADURA HELICOIDALES ADYACENTES QUE PROPORCIONAN UN CANAL DE RODADURA (R) CON UN TORNILLO PARA BOLAS QUE SOPORTAN LA CARGA (17) QUE ENCAJA EN EL CANAL (R). LA TUERCA TIENE UNA ABERTURA (19) QUE SE EXTIENDE DESDE SU EXTERIOR A SU INTERIOR PARA PERMITIR QUE LAS BOLAS PUEDAN PENETRAR EN EL CANAL (R). UN CRUZAMIENTO DE ENCAJE COMPRESIBLE (21) MOLDEADO PARA QUE SE INSERTE POR COMPRESION EN LA ABERTURA PROPORCIONA UN CONDUCTO DE RETORNO DE LA BOLA AXIALMENTE DIAGONAL (24) EN SU CARA INFERIOR PARA CONDUCIR LAS BOLAS DESDE UNA PARTE A LA OTRA DE LAS VUELTAS ADYACENTES (22,23) SOBRE UNA SUPERFICIE INTERMEDIA DE ESPACIO ENTRE ACANALADURAS (12) EN EL TORNILLO HACIA UNA PARTE DE OTRA VUELTA PARA HACER QUE VUELVAN A CIRCULAR. EL CRUZAMIENTO TIENE PARTES OPUESTAS CON PROYECCIONES EN QUE PENETRA LA ACANALADURA DE LA TUERCA (27) FORMADAS PARA QUE ENCAJEN EN LAS VUELTAS Y DEFINAN LAS PARTES DE VUELTA NO OCUPADAS CUANDO LAS PROYECCIONES DEJEN LA ABERTURA TRAS LA INSERCION. SE PUEDEN ALOJAR RETENEDORES DE CUÑA (43) EN EL CRUZAMIENTO UNA VEZ INSTALADO Y CON FINES DETERMINADOS.
