Description

Nipplo autobloccante per raggi di ruote a raggi e metodo per la realizzazione del m edesimo
Descrizione
La
quando avvitata nel foro filettato. Preferibilmente, detta sede ? ricavata in una posizione intermedia del foro ed ancor pi? preferibilmente in una posizione distanziata da detta testa, ovvero compresa tra la testa ed una imboccatura assialmente contrapposta del foro filettato.
Nylon.
Un metodo preferito per la fabbricazione di un nipplo secondo l?invenzione comprende le fasi di:
Nella testa e nello stelo sono preferibilmente ricavate rispettive chiavi di manovra 6a, 6b per ruotare il nipplo 1 rispetto al raggio a scopo di avvitatura. La prima chiave di manovra 6a
con mantello discontinuo, ad esempio per la previsione di un taglio 13. In alternativa ? previsto di utilizzare l?elasticit? stessa dell?inserto 10 oppure una molteplicit? di discontinuit? parziali sul suo mantello.
Nell?inserto 10 ? definito un passaggio 14 il cui
stampaggio da tondino metallico preventivamente raddrizzato e tranciato; il semilavorato S ? conformato cos? da definire le geometrie esterne del nipplo, inclusa la testa 5, lo stelo 4 e le rispettive chiavi di manovra 6a,b.
Il semilavorato S viene quindi forato assialmente con ottenimento del foro 7 e della imboccatura 9, come mostrato in figura 3.
