![]() due to the so-called "manufacturing-in defect". It was established that the fracture of the tooth occurred due to an initial crack existing in its base, which originated during the gear’s manufacturing, i.e. The paper presents calculations of the stress variations cycles’ number for one tooth, as well as of the fracture mechanics parameters – the critical stress intensity factor and critical crack length. The gear was, according to the manufacturer’s certificate, made of the cast steel GS 40 MnCrSi3 V. The bucket-wheel excavator, TAKRAF SRs 2000 × 32/5.0 was employed on the excavation of barren soil for 5.000 h (a few weeks more than a year after the assembly) when the fracture of the tooth of the girth gear, which enables the circular motion of the upper structure of the bucket-wheel excavator, occurred. Skupina.Premature damages and fractures of components and structures of bucket-wheel excavators at open-pit mine often occur in exploitation, caused either by inadequate design or insufficient knowledge of the material properties, welded joints and flaws in component production technology. ![]() ![]() Slušatelji bodo dobili tudi nekaj napotkov v zvezi s prevzemanjem odgovornosti za bolj ali manj zahtevna popravila, kdaj je to vsakodnevna rutina in.
