Abstract

Gearing of different sizes and with different manners of loading are indispensable component of machines and devices. If during the periodic inspection a defect is found, the following question arises: how long such a gear-gearing can still safely operate. To be able to answer this question we have developed a theoretical model for determination of service life of gears on the basis of the shape factors and tooth stress intensity factor Z obtained from a model for generation of actual loadings. 1 Introduction Gearings mutually differing in shape and manner of loading are vital parts of all machines and devices. The most frequent loadings are random loadings of variable amplitude. To be able to determine the service life of such gearings it is very important to take into a
