Abstract
In the contemporary industry of machine manufacture, the analysis of the interplay between machine elements that are susceptible to friction is of paramount importance. The magnitude and qualities of this friction have a direct impact on the efficiency of mechanisms, their longevity, and their dependability. However, friction is not solely a resistive force to be surmounted, but it also has latent potential to engender heat, oscillation, and attrition. Coulomb’s law, which governs the ratio of friction force to normal force, is the central point of investigation for academics. Precise determination of the friction coefficient, as well as comprehension of the dynamics of this phenomenon, can profoundly enhance the performance and longevity of mechanisms. This is especially true in the context of incessant growth and integration of automatic systems, where even a minor shift in frictional characteristics can have momentous implications on the operations of all machinery.
As per the esteemed Journal of Friction and Wear (2019), a conspicuous surge in the longevity of machines, up to 15-20%, can be attained via rectifying the geometric parameters of kinematic pairs. However, notwithstanding the multitude of publications on this matter, the issue of the numerical correlation between said geometry and the level of wear remains unresolved. The State Institute of Mechanical Engineering (2020) has reported that a staggering 60% of equipment malfunctions are attributable to the imprudent selection of geometric parameters.

Keywords: kinematic pairs, geometric parameters, wear, optimization, mathematical model, experimental studies.
