  • Patent number: 10208794
    Abstract: A water lubricated composite thrust bearing of a nuclear main pump has a stainless steel base and an engineering plastic layer. The stainless steel base is provided with a concave-convex surface connected to the engineering plastic layer. The concave-convex surface and the engineering plastic layer are compositely molded by means of thermoplastic compound molding. A ratio of the area of the concave-convex surface to the area of an orthographic projection of the concave-convex surface on the stainless steel base ranges from 1.2 to 2. By means of the concave-convex surface and a specific bonding property obtained after fusion of a rough face and the engineering plastic layer, the concave-convex surface is bonded with the engineering plastic layer, thereby forming a reliable composite thrust bearing that is physically connected onto a whole.
