Abstract
Numerous factors influence tribological wear of steel rollers used in conveyor belts. The difficulty in precise determination of these factors results from, among others, a complex and not completely explored wear mechanism. Corrosive and fatigue damages of conveyor belt rollers start mainly on the coat surface. The present article describes studies on the influence of processing technology of the roller coat surface by means of shot penning method in the context of fatigue strength improvement. Compressive stresses formed due to shot penning reach maximum value just below the roller coat surface. The values of compressive stresses reach about half of the proof stress of the steel they are made of. In result of the carried out experimental model tests it was found possible to significantly improve the properties of the top surface layer of the roller coats, and especially to increase fatigue strength, fatigue corrosion resistance, resistance to cracking caused by stress corrosion and the like.
