Abstract

La testa a snodo sferico (1) è in uso accoppiata ad un dispositivo di movimentazione e comprende:un primo corpo sferico (6) realizzato in acciaio e nel quale è ricavato un foro diametrale passante (7) in uso impegnato da un primo organo del dispositivo;un anello (8) nel quale è alloggiato forzatamente ma libero di ruotare il primo corpo (6); ed un secondo corpo in acciaio (2) presentante mezzi a vite (3 e 4) per l'attacco ad un secondo organo del dispositivo, ed un occhiello (5) nel quale viene piantato l'anello (8).L'anello (8) almeno in corrispondenza dello strato interno prossimo alla superficie di contatto con il primo corpo (6) è realizzato in materiale sinterizzato in modo da definire una porosità nel materiale; questa essendo impregnata da un prefissato lubrificante.
