| titleOfInvention | Production method of front and rear ring bearing inner rings |
| abstract | A method for producing inner rings of front and rear ring bearings is used for new process application, production and solidification of new materials of the front and rear ring bearings. The bearing inner ring is formed by precision investment casting of an alloy steel base material, precision investment casting is carried out, a bearing channel is formed by laser deposition of a nano alloy powder material, after numerical control turning and milling composite center machining and numerical control forming grinding, the whole bearing is treated by black zinc plating, and a salt spray test needs to reach 200 hours. The precision investment casting process is adopted, so that the dimensional precision and the surface roughness of the bearing inner ring and the material utilization rate can be effectively improved; the deposition of the bearing channel adopts the alloy nano powder with high mechanical property, high wear resistance and corrosion resistance, adopts full-automatic high-power and large-spot laser deposition equipment, and can control the deposition deformation of the thin-walled workpiece through laser deposition, reduce the subsequent machining allowance and improve the machining efficiency; after the process flow of the bearing inner ring is solidified, the stability of the product quality, the service life and the equipment fighting time can be greatly improved. |
