Abstract
During long-term operation of mechanical transmissions in the modes of alternating and cyclically repetitive loads, significant contact stresses arise that change according to certain cyclic laws. A feature of contact stresses are large gradients of their distribution, as well as locality. The process of fatigue failure occurs as a result of the initiation and development of microcracks. The nucleation and development of microcracks is significantly affected by the state of the surface, the nature of loading (contact stresses, friction, the presence of a lubricant layer, etc.), material properties (mechanical characteristics, hardness, tendency to harden or accumulate plastic deformations), scale factor, temperature, corrosive effect of the environment, etc. To study the wear resistance of gearing and friction transmissions, rolling bearings, laboratory equipment was designed and methods were developed that allow physically modeling the processes under study.
