Description
Przedmiotem wynalazku jest sposób umacniania warstwy wierzchniej elementów ciegien lancuchowych zwlaszcza ciegien roboczych maszyn górniczych.W celu poprawienia trwalosci zmeczeniowej i odpornosci sciernokorozyjnej elementy ciegien lancucho¬ wych takie jak lancuchy ogniwowe i ich elementy zlaczne poddaje sie zabiegowi kuleczkowania lub srutowania.Zabiegi te prowadza do utwardzenia powierzchniowego i wywolania w warstwie wierzchniej korzystnych napre¬ zen sciskajacych. Zabiegi umacniania zgniotem powierzchniowym wykonywane sa obecnie dla elementów ciegien w stanie nienapietym. Powoduje to, ze korzystny efekt umocnienia warstwy wierzchniej wykorzystywany jest tylko czesciowo.Sposób umacniania elementów ciegien wedlug wynalazku polega na tym, ze elementy ciegna napina sie sila rozciagajaca a nastepnie poddaje sie ubijaniu strumieniowemu. Uzyskuje sie dzieki temu wywolanie w war¬ stwie wierzchniej wyzszycli wstepnych naprezen sciskajacych, niz to ma miejsce w przypadku elementów uma¬ cnianych w stanie nienaprezonym.Zwiekszenie wartosci naprezen sciskajacych w warstwie wierzchniej znacznie podnosi trwalosc zmeczenio¬ wa elementów ciegien lancuchowych. Uzyskuje sie dzieki temu zwiekszenie zywotnosci elementów ciegien i podniesienie niezawodnosci dzialania ukladów ciegnowych maszyn górniczych. PL
