Creating of gearboxes range models on the basis of technical characteristics and its verification through practical application tomining mechanization

Abstract

Gearboxes used on mining machinery work under conditions of exceptional changes in working loads. Given the not negligible investment in purchasing the gearboxes and maintenance costs due to the failure of his elements, it is very important that they have a satisfactory service life. Based on their technical characteristics, a model will be created using the PROMETHEE method with the aim of ranking each of the offered alternatives. Model verification will be performed on the basis of hours worked in the practical application of the reducers analyzed.
