Gear Drives Solution For A Large Steel Mill

The screw-down mill stands at a large steel mill in Pennsylvania was experiencing continuous problems with the gear drives. The material of the existing manufacturer’s gear was breaking down, which caused cracks, fatiguing, broken teeth due to inherent designed duty-cycle stresses.

A meeting with the mill’s engineers, purchasing manager, and hot mill managers, was held at Delroyd’s Niagara Falls facility to review the problem and determine why the existing gearing design was failing so rapidly, and what could be done to solve the problem and improve the gearing life.

The Delroyd team reverse-engineered the screw-down gearbox to develop a more robust solution. The bronze gear material was changed to manganese for enhanced yield and overall strength. A larger radius and shot peen process was added to the root of the worm thread hence reducing the root stresses.

The new Delroyd gearbox design extended the gearing life from 3 years to more than 6 years. Based on the redesigned mill stand gearbox success, the customer awarded Delroyd with orders for additional new complete gearboxes, spare worm/gear sets, and additional gearbox rebuilds.
