Wear-resistant and corrosion-resistant gearbox gear and manufacturing process thereof

The invention relates to the technical field of gears, in particular to a wear-resistant and corrosion-resistant gearbox gear which comprises a gear body, a wear-resistant tooth sleeve is arranged on the outer side of the gear body in a sleeving mode, an oil collecting frame is arranged on the surface of the wear-resistant tooth sleeve, an oil seepage piece is arranged in the oil collecting frame, and a plugging mechanism is arranged on the surface of the oil collecting frame. Lubricating oil contained in the oil collecting frame lubricates the surfaces of the gear body and the wear-resistant tooth sleeve after seeping out, and surface wear of the wear-resistant tooth sleeve is reduced; the wear-resistant and corrosion-resistant gearbox gear and the manufacturing process thereof have the beneficial effects that the wear-resistant tooth sleeves are additionally arranged on the teeth of the gear body, the wear-resistant tooth sleeves are of replaceable structures, and the wear-resistant tooth sleeves are direct
