(54) ЩЕТОЧНЫЙ УЗЕЛ ЭЛЕКТРИЧЕСКОЙ МАЩИНЫ(54) ELECTRICAL MASK BRUSH KNOT
1one
Изобретение относитс к элв стрическим машинам с электромагнитным возбуждением , а именно к конструкции щеточно-контактного узла.The invention relates to electric machines with electromagnetic excitation, namely, the design of the brush-contact unit.
Известны конструкции щеточно-контактных узлов, ресурс щеток которых определ етс величиной рабочего хода щеточной пружины от первоначального сжатого состо ни до конечного рабочего положени , обеспечивающего необходимое давление на кольцо UjDesigns of brush-contact assemblies are known, the brush life of which is determined by the magnitude of the working stroke of the brush spring from the initial compressed state to the final operating position providing the necessary pressure on the ring Uj
Наиболее близким к предлагаемому техническому решению вл етс щет) . точный узел, содержапщй угольную щетку с упорным буртом и цилиндрической поджимной дружиной, щеткодержатель с упором и крышкой |;2.j..The closest to the proposed technical solution is the brush). exact knot, containing a carbon brush with a thrust collar and a cylindrical pressing gang, a brush holder with an emphasis and a lid;; 2.j ..
Однако конструкци щетки также имеет ограниченньй ресурс и не ис ключаёт ее замену в процессе экспдуатации электрической машины.However, the design of the brush also has a limited resource and does not exclude its replacement in the process of electric machine production.
Цель изобретени - увеличение ре сурса работы щеточного узла без увелй«йни его габаритной.The purpose of the invention is to increase the resource life of the brush assembly without increasing its overall size.
Поставленна цель достигаетс тем, что щеточный узел снабжен дополнительной щеткой, установленной внутри подзкимной пружины и выполненной за одно целое с упорным буртом.The goal is achieved by the fact that the brush unit is provided with an additional brush mounted inside the podzkim spring and made in one piece with the stop collar.
Кроме того, щеткодержатель снабжен щупом, установленным в отверстии, выполненном в крышке щеткодержател .In addition, the brush holder is equipped with a probe installed in the hole made in the cover of the brush holder.
На фиг. 1 представлен один из вариднтов конструкции щетки и щвточto . ного узла в целом; на фиг. 2 - разрез А-А на фиг. 1 (возможные варианты )..FIG. Figure 1 shows one of the various designs of the brush and of the brush. node as a whole; in fig. 2 shows section A-A in FIG. 1 (possible options) ..
Электроконтактна щетка 1 снабжаетс упорным буртиком 2 с канатиком The electrocontact brush 1 is supplied with a stop collar 2 with a cord
«5 3. Упор 4 щеткодержател 5 ограничивает ход щетки в процессе ее износа, а продольный паз 6 позвол ет перемещатьс и токосъемному канатику 3, Крьш1ка щеткодержател 7 может иметь "5 3. The stop 4 of the brush holder 5 restricts the stroke of the brush during its wear, and the longitudinal groove 6 allows movement of the current collecting cord 3, Kirsch of the brush holder 7 may have
20 отверстие 8 дл контрол степени износа щетки. Резервна половина щетки размещаетс внутри поджимной пружины 9 и, опира сь на буртик 2 и крышку20 aperture 8 to control the degree of wear of the brush. The reserve half of the brush is placed inside the gland spring 9 and, resting on the shoulder 2 and the cover
