Abstract
The article is devoted to the problems of modernization of the existing fleet of metal-cutting machines. The purpose and objectives-to determine ways and practical recommendations for resource saving in the production of machine components for the manufacture of complex products. The methods used are comparative computational experiments to determine the performance characteristics of sets of replaceable gears. The presented material contains practical recommendations on the choice of evaluation indicators and improvement of sets of replaceable gears of two-pair guitars of various gear-processing machines (5B12, 5A308P, 5111 and 5K32) based on the results of research. Confirmed the possibility of improving the characteristics of kits while maintaining the number of wheels in the kits. In conclusion, it is noted that the proposed solutions contribute to an increase in the integral quality index by 1,2857 – 6,3742 times, a decrease in the total weight of the wheels of the set by 1,4824 – 3,3093 times, an increase in the number of realized gear ratios by 1,2622 – 3,7525 times, an increase in the average density of the values of the gear ratios by 1,2136 – 3,7781 times.
