“…Some examples are the regeneration of forging tools and parts of the forging industry [ 11 , 12 , 13 , 14 , 15 ], where it was pointed out that the function of the damaged part can be restored very quickly and thus achieve savings in terms of downtime, savings on material and energy, employment etc. Similar principles are emphasized in papers [ 16 , 17 ], on examples of construction machinery parts, in works [ 18 , 19 ] on examples of heavy mining equipment parts, as well as responsible parts of machine constructions, such as gears, whether they are the author’s own research [ 20 , 21 , 22 ] or research by other authors [ 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. In all the mentioned research, it has been shown that hard-facing achieved at least the same characteristics of the applied welds in comparison to the basic materials, while it is often the case that their resistance is even higher.…”

Hard-facing as a type of the coating depositing is increasingly used today. Physical-chemical-metallurgical characteristics of contact layers in tribo-mechanical systems depend on the operating conditions and the conditions under which the work surfaces were created. That is the reason the influence of the processing procedures and regime, used in the contact surfaces formation, on development of the wear process of contact elements, is being considered ever more. To determine the influence of the hard-facing technology on characteristics of the gears’ working surfaces, the experimental investigations were performed on samples hard-faced on the steel for cementation, by varying the filler metals (FM) and the hard-facing regimes. The samples tested were hard-faced by five “hard” and three “soft” filler metals. Experimental investigations included measuring the hard-faced layers’ hardness and determination of their microstructure, as well as the wear resistance in the laboratory conditions, on tribometer and on a specially designed device for tests in the real operating conditions of gears. The wear intensity was monitored by the wear trace’s width in the laboratory conditions and by the share of the teeth surfaces affected by the destructive pitting in the operating conditions. The results obtained were compared to results of the base metal (BM) tests, which provided the certain conclusions on which filler metal and which welding procedure are the optimal ones for regeneration of the worn teeth surfaces.

“…Reducing the friction of 100Cr6 bearing steel resulted in reduced wear and increased lifetime. (Feng et al, 2020) considered a cause of failure of a secondary driving helical gear steel in a transmission system of an electric vehicle. The gear was made of the 20CrMnTi steel.…”

During the process of regeneration of machine parts, certain phenomena occur that have a significant impact on the loss of their working ability. Hereditary properties are expressed by the interdependence of geometric and physical-mechanical-metallurgical parameters of gear teeth created during the technological operations of regeneration of worn teeth by hard-facing. The influence of the type of additional material (electrodes and their combinations) on the tribological characteristics of welded gear teeth was considered, whereby the so-called hard additional materials were applied. Those are the additional materials that give the required surface hardness of the teeth without subsequent thermal or thermochemical treatment. This research did not involve the regeneration of specific worn gears removed from machine systems, but the new gears were made, which were then damaged and then regenerated by hard-facing using the shielded metal arc welding (SMAW) procedure. Thus, all the tested gears were made of the same material, belonged to one batch and were machined on the same machines with the same machining regimes. The tests were performed on samples made of 20MnCr5 steel for cementation, on a tribometer by the “block on disc” method, which was designed to simulate the operating conditions of coupled teeth of concrete gears in the exploitation conditions. Based on the conducted tribological tests, the average coefficients of friction and topography of the surfaces were determined by measuring the wear trace and it was defined which additional materials give the best tribological characteristics of the surfaces of gears regenerated by hard-facing.

Hałas emitowany przez przekładnie jest jednym z ich negatywnych parametrów/charakterystyk. Najważniejszym czynnikiem wpływającym na emitowany hałas jest błąd przełożenia, który ma związek z ogólną sztywnością zazębienia. Sztywność zazębienia nie może być precyzyjnie zaprojektowana, ale można ją analizować -na przykład: stosując metodę elementów skończonych. Stosując system/pakiet MES, aby określić precyzyjnie rzeczywiste wartości sztywności oraz naprężeń, jest bardzo ważnym aby opierać się na jak najbardziej poprawnym modelu 3D -jak to tylko jest możliwe. Stosowano wiele metod modelowania kół zębatych, jednakże tylko nieliczne z nich pozwalają na utworzenie modelu o wysokiej dokładności. Jedną z metod modelowania jest modelowanie parametryczne, które nie tylko pozwala na stworzenie poprawnego zarysu ewolwentowego powierzchni zębów zazębionych kół, ale także umożliwia parametryzację całego modelu przekładni. Oznacza to, w konsekwencji, że można go zmieniać w zależności od zaledwie kilku parametrów. Inną metodą używaną do stworzenia modelu koła zębatego jest wygenerowanie go na podstawie chmury punktów. Użyta chmura punktów umożliwia wygenerowanie modelu zazębienia jako zakrzywionych powierzchni.
