Abstract

The paper is focused on the influence of gearing material and thermal or chemical-thermal processing of wheels on the results of the strength calculation carried out in accordance to the standard, in particular on the safety factor. This effect is examined on a gearbox that was part of the steel coil production line in the integrated steel plant. Due to changes in production, the load on the gears increased. Thus, the result of this work is the selection of new materials for the two-speed gearbox and their heat treatment to meet the safety conditions of the gearing mechanism without changing the geometrical parameters of the gearbox.
