An Investigation into Plain Journal Bearing Behaviour Including Thermo-Elastic Deformation of the Bush

This paper describes a theoretical investigation into the effect of thermoplastic bush deformation and journal thermal expansion on the behaviour of a cylindrical bore bearing fed by two axial grooves orthogonal to the load line. The main conclusions which follow from this work are that thermoelastic bush deformation is an important factor in predicting bearing operation for a given load duty. It shows that shaft expansion has a very significant influence also.
