Gear Teeth of Ball Mills: Wear, Restoration, and Mathematical Modeling

This study focuses on the restoration of large-module gear teeth for ball mills through electroslag surfacing, emphasizing practical results and mathematical modeling. The research explores wear mechanisms, restoration processes, and laboratory experiments to evaluate the hardness and surface roughness of restored teeth. Optimal surfacing modes were identified, including key parameters such as current strength, slag bath voltage, and cooling water flow rate. These parameters ensure the durability and operational efficiency of restored gears. Mathematical modeling and experimental analysis have provided equations that describe the dependencies between surfacing modes, wear resistance, and mechanical properties. The findings are highly relevant for industries engaged in gear restoration, enabling significant cost reductions and improved reliability.
