| Popis: | U radu se predstavlja dio istraživanja koja se odnose na tribološke aspekte kočnica rudarskog stroja za podizanje tereta. Istraživanje se sastoji od eksperimentalnog određivanja jačine trošenja za tarni materijal u dodiru s rubovima kočnicama. Oslanjajući se na uobičajena teoretska razmatranja i eksperimentalne modele, najprije je izmjeren intenzitet trenja tarnog materijala u skladu s početnom brzinom ruba kočnica, površinskom hrapavosti ruba i kontaktnim pritiskom između kočničke papuče i ruba. Zatim je primjenom metode najmanjih kvadrata statistički određeno djelovanje težine parametara na intenzitet trošenja. The paper represents a part from the researches referring to the tribological aspects of the brakes of the mining hoisting machines. The study consists in experimental determination of the wear intensity for the friction material in contact with rim brakes. Relying on usual theoretical considerations and experimental models, first was measured the wear intensity of the friction material in accordance with the initial speed of the brake rim, the surface roughness of the rim, and the contact pressure between the brake shoe and the rim. Secondly, the least-squares method was applied for the statistical weight determination of the parameters on the wear intensity. |
