Wear assembly for machinery 5 It comprises wear and support elements (110, 120) and a retaining pin (130) for attaching them to each other. The retaining pin (130) has protrusions (140, 150) and the wear element (110) has cavities (160, 170) such that the protrusions (140, 150) can be passed therethrough. The support element (120) has a recess (180) for receiving one of the protrusions (150). In a first 10 position the retaining pin (130) can be inserted into the wear and support elements (110, 120). In a second position one protrusion (140) is snap fitted in one cavity (160) so the retaining pin (130) can not be rotated to the wear and support elements (110, 120) and the other protrusion (150) is received into the recess (180) abutting an inner surface of the wear element (110) such 15 that the retaining pin (130) can not be displaced axially to the wear and support elements (110, 120). c'Jn Lii |
