A hub-spider assembly for a Hooke's joint in which the arms of the spider (2) include a first shaft (4), having a through-hole (41) bored in a central boss (42), the through-hole (41) axis being perpendicular to the axis of the first shaft (4), and a second shaft (5) coupled with slight interference with the first shaft (4) in its through-hole (41). At least one end of the shaft (5) is threaded or predisposed equivalently for coupling. In a double Hooke's joint a rotating coupling is realized by a bearing pair (31, 32) housed in the branches (11, 12) of a hub (1) and support the second shaft (5), the bearings (31, 32) being held in place by end ring-nuts (61, 62) at the threaded pivot ends (51, 52) of the shaft (5). |
