Abstract

The invention discloses an antifriction wear-resistant slewing bearing with a bionic structure and a preparation method thereof. The surfaces of an inner ring and an outer ring of the slewing bearing are respectively processed into regular hexagonal bionic microstructures, and a solid lubricant can be more fully spread on the surface of a matrix through the bionic microstructures to form a layer of lubricating film, a role in reducing friction and material abrasion is placed, the composite solid lubricant comprises graphite, tin, a multi-element two-dimensional material, phenolic resin and silicon carbide, the bionic microstructures of the inner ring and the outer ring of the slewing bearing are filled with the composite solid lubricant in a vacuum infiltration mode, and the slewing bearing of the bionic structure is obtained. Compared with the traditionalslewing bearing, the antifriction wear-resistant slewing bearing with the bionic structure has excellent antifriction wear-resistant properties, lower friction coefficient and wear rate, higher use stability and longer fatigue life.
