More Information
Summary:The invention relates to a preparation method of an oil bearing. The method comprises the steps of powder mixing, forming, sintering, finishing, cleaning, drying and the like. The powder metallurgy copper-based oil-retaining bearing has the remarkable characteristics that an optimally designed component system is adopted for preparation, the powder metallurgy copper-based oil-retaining bearing suitable for the electric tool with the rotating speed of 25000-35000 revolutions per minute is prepared with a small element addition amount through control of a production process, the abrasion loss is smaller than or equal to 0.05 mm when the powder metallurgy copper-based oil-retaining bearing operates for 1000 hours at the rotating speed of 25000-35000 revolutions per minute, and the abrasion loss is smaller than or equal to 0.05 mm. And the adopted process is suitable for industrial mass production, the cost is effectively reduced, the performance of the product is effectively improved, and good economic benefits
