In many cases the surfaces through which various machine elements come in contact can be represented as cylinders which can be a good approximation of the real surfaces in contact. The paper presents the mathematical modeling of the pressure distribu

This paper deals with the mathematical modelling of the normal forces distribution and of the contact pressure between the chain and the tensioning guide. In the first step, using Hertz theory, it is performed, for two cases, the modelling of normal

The lubrication in chain drives has a major influence on their dynamic behaviour, wear and lifetime. The paper presents the finite element analysis of the lubrication for a given chain drive with a tensioning guide. The analysis is achieved for diffe
