Abstract (en)
[origin: WO2013030335A1] The invention relates to a mechanical system (1) comprising a support (10), a tooth (20) and a device (30) for interconnecting said two components. The device (30) comprises an elastic sheath (40) provided with an inner cavity (48) and an outer wall (44) that is adjustable in a housing (14) of the support (10), and a key (50) that is adjustable in the cavity (48) of the sheath (40). The sheath (40) and the key (50) can be rotated together in a fixed manner about a pivoting axis in the housing (14), between an insertion configuration and a locking configuration, thereby forming a coupling connection between the tooth (20) and the support (10). The inner cavity (48) extends into the sheath (40) along an eccentric axis that is radically staggered in relation to the pivoting axis. The inner cavity (48) is provided with elements for rotatably securing to driving elements (59) arranged on the key (50). The invention also relates to a heavy-construction machine bucket (G) comprising such a system (1), and to a method for implementing such a system (1).
