The invention relates to a retaining system (100) for a wear (30) of a bucket (50) of an earthmoving machine (200). The retaining system (100), in operational use, comprises: i) a bucket body (10) comprising a groove (T) having an inclined side wall (SW1) extending from an upper side (S1) of the bucket body (10); ii) a force multiplier (20) having a shape substantially corresponding to the shape of the trench (T), where the force multiplier (20) is provided with a plurality of through-holes (20-1) spaced apart and distributed over a first surface (SF1) of the force multiplier (20); iii) a wear piece (30) mounted to the edge (E1) of the bucket body (10), where the wear piece (30) and the bucket body (10) form a first interaction interface (I1) extending along the underside (S2) of the bucket body (10) from the edge (E1) beyond the position of the groove (T) by a predetermined distance (d1), where the wear piece (30) and the edge (E1) of the bucket body (10) form a second interaction interface (I2), where the first interaction interface (I1) extends along the underside (S2) of the bucket body (10) by a predetermined distance (d2) from the edge (E1) beyond the position of the groove (T) by a predetermined distance (d2) from the underside (S2) of the bucket body (10). The wear-resistant part (30) is provided with a plurality of receiving holes (98) with internal threads, and the receiving holes (98) are located at positions corresponding to the plurality of through holes (20-1) in the force multiplier (20); and iv) a plurality of bolts (99) disposed in the plurality of through holes (20-1) and held by the internal threads of the plurality of receiving holes (98). One of the wear piece (30) and the force multiplier (20) is provided with at least one projection (PT1, PT2) at the first interaction interface (I1), and the other of the wear piece (30) and the force multiplier (20) is provided with at least one mating recess (RC1, RC2) at the first interaction interface (I1), the first interaction interface (I1) is configured such that, in operational use, relative movement between the wear piece (30) and the force multiplier (20) in a transverse direction (LD) parallel to the first interaction interface (I1) is prevented in order to reduce shear forces acting on the bolt (99).
本发明涉及一种用于土方机械(200)的铲斗(50)的耐磨件(30)的保持系统(100)。该保持系统(100)在操作使用中包括：i)铲斗本体(10)，包括沟槽(T)，该沟槽具有从铲斗本体(10)的上侧(S1)延伸的倾斜侧壁(SW1)；ii)力倍增器(20)，所具有的形状基本上对应于沟槽(T)的形状，其中，力倍增器(20)设置有多个通孔(20‑1)，所述多个通孔间隔开并分布在力倍增器(20)的第一表面(SF1)上；iii)耐磨件(30)，安装到铲斗本体(10)的边缘(E1)，其中，耐磨件(30)与铲斗本体(10)形成第一交互界面(I1)，该第一交互界面沿着铲斗本体(10)的下侧(S2)从边缘(E1)延伸超过沟槽(T)的位置预定距离(d1)，其中，耐磨件(30)与铲斗本体(10)的边缘(E1)形成第二交互界面(I2)，其中，耐磨件(30)设置有具有内螺纹的多个接纳孔(98)，其中，接纳孔(98)位于与力倍增器(20)中的多个通孔(20‑1)对应的位置处；以及iv)多个螺栓(99)，设置在多个通孔(20‑1)中并由多个接纳孔(98)的内螺纹保持。耐磨件(30)和力倍增器(20)中的一个在第一交互界面(I1)处设置有至少一个突起(PT1、PT2)，并且耐磨件(30)和力倍增器(20)中的另一个在第一交互界面(I1)处设置有至少一个匹配凹部(RC1、RC2)，使得在操作使用中防止耐磨件(30)与力倍增器(20)之间沿平行于第一交互界面(I1)的横向方向(LD)的相对移动，以减小作用在螺栓(99)上的剪切力。
