(57) Wear assembly (1) comprising a wear tooth (2) comprising a wall (4) that defines
a pocket (6) and at least one through hole (8, 8') communicating with the pocket,
an adapter (10) with a connection point (12) inserted into the pocket (6) in a removable
manner and defining a pin cavity (14) aligned with the through hole (8, 8'), a blocking
pin (16) between the tooth (2) and adapter (10), inserted in the through hole (8,
8') and in the pin cavity (14) rotatably and comprising at least a first blocking
element (18), and a second blocking element (20, 20') associated to the wear tooth
(2) or to the adapter (10).
The elements (18, 20, 20') are mutually arranged in such a way that, through rotation
of the blocking pin (16) in a direction, the first blocking element (18) intercepts
the second (20, 20') to block the pin in the pin cavity (14). In addition, one of
said elements (20, 20') is deformable so that, through a further rotation in the same
direction, this element disengages from the other element (18) allowing the extraction
of the pin from the cavity.
