The Second Development of Gear Reducer CAD System by Visual Basic Based on AutoCAD

On the basis of the elastic-hydrodynamic lubrication theory proposed by the English engineers Dawson and Higginson the author has described and made a numerical analysis of the scoring of the main gear reduction unit second gear, Proposals aimed at alleviating scoring are also given.
