A patent Dynamic Electroplating Method and Device for Deep Groove Ball Bearing Races
Recently, Anhui Yinqiu Bearing Co., Ltd. filed a patent application for a new electroplating process technology related to deep groove ball bearing rings. The patent, titled "Dynamic Electroplating Method and Supporting Device for Deep Groove Ball Bearing Rings," carries the publication number CN120174458A and was filed in May 2025.
According to disclosed information, this technology belongs to the field of metal surface treatment and precision manufacturing, aiming to address the issue of uneven coating distribution in traditional electroplating processes. The new method employs a rotating drive device to continuously rotate the plating rack within the electroplating tank, ensuring more uniform ion distribution in the electrolyte and thereby improving plating quality.
Additionally, the process introduces a voltage regulation mechanism. During electroplating, the system automatically adjusts the anode output voltage based on the position changes of the rack. When the rack moves to areas farther from the anode, the voltage increases accordingly to compensate for the drop caused by the greater distance, ensuring consistent plating intensity across all parts.
To further optimize electrolyte concentration distribution, the equipment is equipped with a liquid circulation pump that transports high-concentration electrolyte from areas near the anode to the middle and edges of the rack, reducing localized concentration differences.
Overall, this dynamic electroplating method significantly improves the uniformity and density of the coating, thereby enhancing the wear resistance and corrosion resistance of bearing rings. This advancement helps extend the product's service life under complex working conditions.
The patent application reflects Anhui Yinqiu Bearing's continued investment in advancing surface treatment technologies and provides new technical support for the company's development in the high-end bearing manufacturing sector.
