Stamping retainer provided with lubricating oil duct and machining method

The invention discloses a stamping retainer provided with a lubricating oil duct and a machining method. The sliding friction between an existing rolling bearing retainer and a rolling body is too large. An annular groove is formed in the side wall of each pocket of the stamping retainer in the circumferential direction of the pocket, and rounded corners are chamfered between the two side walls ofeach annular groove and the side wall of the corresponding pocket. Microstructures are arranged at the bottoms of the annular grooves. The machining method of the stamping retainer comprises the following steps of material checking; primary machining of the retainer to form a steel ring and finishing treatment; formation of the microstructures; stamping formation of a retainer body on one side ofthe retainer; surface treatment; and riveting. According to the stamping retainer provided with the lubricating oil duct and the machining method, surface-to-surface contact between a traditional retainer and a rolling body i
