[0031] Specifically, as shown in Figure 3 The material of the reinforcing ring 701 is martensitic age steel, and the reinforcing ring 701 is tightly connected with the gear box bearing outer wall body 1 by hot inlay and is subjected to carburizing heat treatment.

[0032] Specifically, as shown in Figure 3 The material of the corrosion-resistant layer 702 is zinc-rich paint, and the material of the wear-resistant layer 703 is ceramic wear-resistant coating.

[0033] In the embodiment: the reinforcing ring 701 is made of martensitic age steel, which has ultra-high strength and good toughness.
