A large class of solid inlaid self-smooth bearings (abbreviated as JDB) is a new type of smooth bearing that combines the characteristics of metal bearings and oil-free smooth bearings. The metal matrix receives the load, and the specially formulated solid smooth material has a smooth effect. Mosaic self-smooth composite data is a new type of extreme pressure solid smooth material, consisting of a metal substrate and a solid smoothing agent paste embedded in a hole or groove in the substrate.
During the conflict, the metal substrate bears most of the load. After the conflict, the solid smoothing agent in the hole or groove is transported or reversed to the conflict surface, forming a smooth and excellent solid transport film on the conflict surface that is firmly attached and evenly covered, which greatly reduces conflict wear. As the conflict progresses, the embedded solid smoothing agent is continuously provided on the conflict surface, ensuring excellent smoothness during long-term operation. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-smoothness. It is especially suitable for heavy-load, low-speed, reciprocating or swinging situations where it is difficult to smooth and form an oil film, and it is not afraid of water erosion and other acid erosion. And scouring.
