THREE-LAYER COMPOSITE SELF-LUBRICATING SLIDING BEARING WITH MODIFIED POLYIMIDE WEAR LAYER AND PREPARATION METHOD THEREOF |
摘要 |
The invention discloses a three-layer composite self-lubricating sliding bearing with modified polyimide anti-wear layer, wherein a porous spherical bronze powder layer is sintered on a surface of a steel plate, characterized in that a self-lubricating sliding bearing sheet is formed by covering the porous spherical bronze powder layer with a modified polyimide anti-wear material layer, and then the self-lubricating sliding bearing sheet is manufactured into an article of sleeve-shaped sliding bearing or bearing bush or thrust washer or sliding-board or friction disc or ball seat structural part according to conventional processes. The process for manufacturing the same includes: preparation of a modified polyimide paste; sintering of spherical copper powder; preparation; coating; sintering of the modified polyimide; finish rolling; cutting and forming. The product of the invention possesses excellent performances of high stiffness, high strength, high-temperature resistance, and lead-free, and is especially applicable for the sliding bearings with heavy loading, variable loading and high PV value. |
