The presented work is devoted to the search for a new design of the toothed belt transmission for the drive of metal-cutting machines. The main constructive solution underlying the modernization of the existing transmission is associated with a change in the shape of the toothed belt teeth pulley to increase durability. The authors propose to consider the effectiveness of the design decisions made through the prism of increasing the load capacity of the toothed belt associated with an increase in the contact length of the arched shape teeth and the reduction of additional friction losses of the belt flanks along the flanges at the pulleys end surfaces designed to restrain the belt from transverse sliding from the pulleys. The authors conclude that a comparative analysis of typical and modernized structures must be based on the postulates of contact areas belt and pulley equality and the belt cross-sectional areas. The procedure of three-dimensional modelling of elements and assemblies of a toothed belt drive for a drill-milling-boring machine type is considered as a basis for a comprehensive further study of their effectiveness and efficiency. Particular attention is paid to the parameterization toolkit in CAD “APM WinMachine”, the construction of algorithms and programs for creating unified toothed belt transmission components taking into account the variable design. The conceptual moment of the study is the proposed procedure for creating a specialized database of parametric design solutions.

Eksploatacja jest zjawiskiem związanym z wyprodukowaniem, sprzedażą obiektu lub systemu i kończy się wraz z jego wycofaniem. Najważniejszym wskaźnikiem jakości eksploatacji jest ekonomia eksploatacji, która wynika z poziomu wykorzystywania potencjału eksploatacyjnego zawartego w obiekcie i systemie - zaprojektowanego przez jego konstruktorów.
