| ABSTRACT This contribution deals with the methodology of a lifetime calculation for gearings of automobile differentials in bending and a contact. Basis of a calculation is an operating loading spectrum whose determination for a differential is very difficult. In this contribution a procedure for a determination of a hypothetic loading spectrum by the mathematical formula with an exploitation of an experiment is published. A calculation of a contact stress and a bending stress in the root is also made by using modified techniques in accordance with appropriate standards. An assessment of gearing service life is based on a calculation of an intensity of damages using Haibach’s theory of a cumulating of damages. But there's no point in to use this method for differential gearing. The new procedure is designed – this new procedure evaluates loading capacity of gearing by a utilization of an ultimate or reliable recommended safety factors which are subjected to the endurance limit. | ||
