Abstract
Изобретение относитс к электромашиностроению и может найти применение в электродвигател х посто нного тока с торцовым коллектором. Целью изобретени вл етс повышение надежности электрической машины посто нного тока. Во врем работы электрической машины из-за разных линейных скоростей в зоне скольз щего контакта между коллектором 4 и прижатыми щетками 7 пружинами 8 происходит неравномерныйй износ последних,что приводит к повороту щеткодержателей 2 вокруг осей 3, установленных на траверсе 1 под воздействием пружин 5, закрепленных на ос х 6. Поворот щеткодержателей обеспечивает равномерное распределение давлени по всей площади скольз щего контакта по мере износа щеток. Это позвол ет сохранить неизменным переходное сопротивление и плотность тока в зоне скольз щего контакта, что улучшает коммутацию электрической машины и повышает ее надежность. 2 ил.This invention relates to electrical engineering and can be used in direct current electric motors with an end collector. The aim of the invention is to increase the reliability of a DC electric machine. During the operation of the electric machine, due to different linear velocities in the zone of sliding contact between the collector 4 and the brushes 7 pressed by the springs 8, the latter wear unevenly, which causes the brush holders 2 to rotate around the axes 3 mounted on the yoke 1 under the influence of the springs 5 fixed on axis x 6. The rotation of the brush holders ensures that the pressure is evenly distributed over the entire area of the sliding contact as the brushes wear. This allows the transient resistance and current density in the area of the sliding contact to remain unchanged, which improves the switching of the electrical machine and increases its reliability. 2 Il.
