AI Technical Summary
Existing silicon carbide bushings are prone to wear in high-wear environments and are unstable when used at high temperatures, affecting their service life.
The design employs a double-layer silicon carbide bushing, including an outer silicon carbide bushing and an inner bushing. The outer bushing contains reinforcing components and a wear-resistant ring, while the inner bushing contains high-temperature resistant components. The structural strength is enhanced by reinforcing ribs, metal mesh, and partitions, and heat is dispersed through multiple heat dissipation layers and flow guiding layers.
It improves the wear resistance and heat dissipation performance of silicon carbide bushings, extends their service life, and enhances their stability in high-temperature environments.
