Abstract

The paper considers the issues of reliability of stone sawing machines using the example of a diamond disk machine. With the help of the probabilistic strength calculations carried out in the work, the main optimal geometric parameters of the gear-rack drive of the disk machine were found: modulus, diameter, width - and it was determined that the resulting operating stresses are very sensitive to changes in the listed geometric parameters. On the basis of the calculated data, graphs of dependencies were built, showing the significance and necessity of using probabilistic calculations, in order to determine the degree of influence of the parameters of the rack and pinion transmission of the disk machine on bending fatigue.
