Sažetak

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.
