[0029] This embodiment provides a convenient way to replace the split pressure wheel. Figure 1-4As shown, it includes a bearing component 100, a wear-resistant component 200 and a bolt 300; the bearing component 100 protrudes from its axial middle part to the periphery to form a mounting portion 110, and the side wall of the mounting portion 110 on one axial side is concave to the other side to form a plurality of mounting grooves 111 arranged around the middle part; the wear-resistant component 200 includes a connected outer peripheral portion 210 and an inner extension portion 220; the outer peripheral portion 210 is arranged around the outer peripheral wall of the mounting portion 110, and the inner extension portion 220 is formed by extending inwardly from the axial side of the outer peripheral portion 210, and is used to be embedded in the mounting groove 111; the bolt 300 is axially installed on the axial groove bottom of the mounting groove 111 and the inner extension portion 220.

[0030] Specifically, the mounting groove 111 of the bearing component 100 adopts a staggered structure, which can distribute the pressure on the front side and the protrusion 112. At the same time, the inner extension 220 of the wear-resistant component 200 is protruded inward, which increases the radial thickness. The above structure is conducive to improving wear resistance and impact resistance; at the same time, the wear-resistant component 200 can be directly installed on the mounting groove 111 and the bolt 300 facing one side through the inner extension 220, or disassembled from it, which is convenient for disassembly and assembly; at the same time, on the basis of the fixation of the bolt 300, a concave-convex embedded structure is also adopted between the inner extension 220 and the mounting groove 111, which increases the strength between the structures and is also more resistant to impact.

[0031] In this embodiment, the installation grooves 111 are arranged at intervals around the middle of the installation portion 110 , and protrusions 112 are formed between the installation grooves 111 .

[0032] Specifically, the installation grooves 111 are arranged at intervals and protrusions 112 are formed therebetween, which is beneficial to increasing the limiting strength and the supporting strength and is beneficial to dispersing the force.

[0033] In this embodiment, the installation groove 111 adopts a structure that is radially narrowed from the outside to the inside.

[0034] Specifically, the radial slot adopts a (gradually) narrowing structure, which is convenient for introducing and embedding the inner extension portion 220 and is beneficial for dispersing the force.

[0035] In this embodiment, a connecting portion 113 is provided between the protruding portions 112 and is arranged to protrude from the axial middle portion of the bearing component 100 .

[0036] Specifically, the protrusions 112 and the connecting portion 113 are integrally formed, which is beneficial to increasing the matching strength between the bearing component 100 itself and the structure, and is beneficial to improving the supporting force and impact resistance.

[0037] In this embodiment, the bearing component 100 has shaft tube portions 120 on both axial sides, and an angular reinforcing plate is provided between the protruding portion 112 and the corresponding shaft tube portion 120 .

[0038] Specifically, an angular reinforcing plate (not shown in the figure) is provided between the protruding portion 112 and the corresponding side (ie, the upper side as shown in the figure) of the shaft tube portion 120, which is beneficial to increase the connection and support strength between the structures.

[0039] In this embodiment, the wear-resistant part 200 adopts a split structure, each of which has the outer peripheral part 210 and the inner extension part 220, and adjacent outer peripheral parts 210 are connected.

The inner extension 220 extends inward from the middle of the outer peripheral portion 210, and at the same time, the two side portions abut against the two side protrusions 112. This can increase the structural strength and disperse the force, thereby improving the impact resistance and making the pressure wheel durable.

[0043] In this embodiment, the plurality of mounting surfaces of the radial side wall of the mounting groove 111 are respectively planes 1111 , and rounded corners 1112 are provided on both sides of the plane 1111 .

[0044] Specifically, the mounting groove 111 in the figure includes radial side walls and an axial bottom wall, wherein the middle and both sides of the radial side walls have spaced-apart planes 1111, and rounded corners 1112 are provided between and on both sides of the three planes 1111. This structure facilitates processing and production, installation and introduction, and realizes smooth transition and anti-friction fit.
