摘要
A wear assembly of an earth-moving machine's bucket comprises a male part (1) and a female part (2), both of which in turn comprises a nose (10) (male part) or cavity (20) (female part) provided with an upper contact surface and a lower contact surface. The upper contact surface comprises an upper front contact portion (14, 24) that extends backward from the tip of the nose or the bottom of the cavity and the lower contact surface comprises a lower front contact portion (13, 23) that extends likewise, one of said upper and lower front contact portions being concave and the other being convex. Analogously, the upper contact surface comprises an upper back contact portion (16, 26) that extends forward from the base of the nose or the mouth of the cavity, and the lower contact surface comprises a lower back contact portion (15, 25) that extends likewise, one of said upper and lower back contact portions being concave and the other being convex.
