“…The first approach consists of optimizing the design parameters of the crusher, in particular the shape and profile of the working bodies and bearing assemblies [22], ensuring effective lubrication of the bearing supports of the rotors [23,24] and reliable connection of the rotors with their drives [25]. The development of rational routes [26], the choice of processing modes of functional surfaces and equipment [27,28,29] to ensure the accuracy and quality of working surfaces [30,31,32] plays an important role during the manufacture of new parts for the restoration of worn parts of machines and equipment. Special attention is paid to careful static and dynamic balancing of rotors [33,34].…”

A new hardfacing alloy within the Fe-Ti-Nb-Mo-V-C alloying system was utilized to restore the working surfaces of cone crusher rotors using Flux-Cored Arc Welding (FCAW). TiC, NbC, Mo2C, VC, Mn, and ferromanganese powders were selected as the base materials for manufacturing the welding wire. The resulting hardfaced layer exhibits a composite structure, with manganese austenite as the matrix and complex solid solution reinforcements with a NaCl structure, closely resembling the formula (Ti0.3Nb0.3Mo0.3)C. The primary advantages of this hardfacing alloy include its capacity for intensive deformation hardening along with high abrasion resistance. The hardness of the hardfaced layer is approximately 47 HRC in the as-deposited state and increases to around 57 HRC after work hardening, surpassing typical hardfacing alloys derived from high manganese steel by about 10 HRC. The efficacy of the alloy was tested in restoring rotors made of Hadfield steel in a PULVOMATIC series crusher model 1145, during the milling of sand-gravel mixtures ranging from 25 to 150 mm into spalls measuring 5 to 20 mm. With an average productivity of approximately 60 tons per hour and a production volume of 300 tons, the utilization of this hardfacing alloy enabled multiple restorations of the rotor while maintaining productivity at a level of 15 thousand tons of spalls.

“…The formation of surfaces of thin-walled parts with variable low stiffness requires a consideration of a number of factors that could prevent the achievement of technological requirements for the product [6,7]. Such factors are: deviations from a given shape that increases during processing, vibrations, thermal deformations and errors caused by tools, tool-path accuracy, technological equipment [8,9] and fixtures [10,11].…”

The disadvantage of the geometry of thin-walled parts, in terms of processing, is the low ability to resist static and dynamic loads. It is caused by the elastic deformation of elements with a low stiffness. Modelling approaches for the evaluation of deflections during machining are presented. Mathematical models of deflections, cutting forces and harmonic response are proposed. The processes of material removal and deflection of a thin-walled sample at the critical points are modelled. A frequency analysis was performed, consisting of a modal analysis of natural frequencies and a harmonic response analysis. As a result, a graph of the deflections amplitude from the frequency of driven harmonic oscillations is generated. The analysis of the obtained values was performed. As a result, the resonance frequency and maximum amplitude of oscillations for the operating parameters are determined.

“…There are several problems associated with the analysis of the engagement zone [18,19,20], which are characteristic of various types of mechanical gears (spur, helical, bevel, worm, etc.). Large-scale researches of the various types of mechanical gears designs in developed computer-aided design systems and authoring specialized software are carried out.…”
