Beschreibungen/Notizen

• The bearing assemblies of the work rolls of high-speed cold-rolling mills are the most heavily loaded components of the working stands. The short service life of the rolling bearings is due to overheating. It is shown that it is possible to eliminate this disadvantage of rolling bearings either by providing, based on the developed thermal model, the appropriate oil-feed cycle in the oil–air lubrication system or by selecting, using the proposed method, the viscosity grade of the mineral oil that minimizes the temperature of the lubricating film in the contact zone.
