FIELD: mechanical engineering. ^ SUBSTANCE: device comprises braking belt with friction linings and braking pulley provided with cooling units inside it. The cooling units are made of thermopiles which are composed of thermocouples with electronic and hole conductivity. The thermocouples are made of rods set in the openings in the braking pulley. The heat insulating elements are arranged over the pulley width. The thermopiles are arranged uniformly over the periphery of the pulley from the side of its nonoperating surface. The method comprises making cooling units as thermopiles which comprise thermocouples with electronic and hole conductivity. Two thermocouples-thermoelectric generators are interposed between the thermal electric coolers. The end thermocouples, i.e. cold junctions of thermopiles-thermoelectric generators are interconnected in parallel, and end thermocouples, i.e. hot junctions of thermopiles-thermal electric coolers are connected with a DC power source. ^ EFFECT: simplified structure and prolonged service life. ^ 4 cl, 5 dwg |
