Abstract

Patente de Invenção: <B>"MOTOR ELéTRICO COM UM COLETOR"<D>. Motor elétricos exibem, por exemplo, um induzido, um coletor e um eixo para o apoio do induzido e do coletor. Em ambos os lados da combinação do induzido e coletor o eixo exibe segmentos de eixo, que são peças constituintes de mancais de deslizamento, aos quais pertencem buchas de mancais de deslizamento sinterizados, as quais são embebidas em material lubrificante oleoso. De acordo com a invenção, entre o coletor (8) e o mancal de deslizamento (10) em conjunto com o eixo (9), próximo ao coletor, é conjugado um elemento construtivo (25) rotativamente simétrico, o qual, por exemplo, é desenvolvido em forma de um disco anelar e exibe um revestimento (26), na direção da bucha de mancal de deslizamento sinterizado (12) com uma tensão superficial baixa em relação ao material do eixo (9). Material lubrificante oleoso se arrastando a partir da bucha de mancal de deslizamento sinterizado (12) é impedido de continuar arrastando-se, por este revestimento (26), o qual por exemplo constitui-se de politetraflúoretileno, e com isso mantido afastado do coletor. Isso evita danos de operação ao motor elétrico (2).Invention Patent: <B> "ELECTRIC MOTOR WITH A COLLECTOR" <D>. Electric motors display, for example, a armature, a collector and an axle for supporting the armature and the collector. On both sides of the armature and collector combination, the shaft displays shaft segments, which are constituent parts of plain bearings, to which sintered plain bearing bushings belong, which are embedded in oily lubricating material. According to the invention, between the collector (8) and the slide bearing (10) together with the shaft (9), close to the collector, a rotatingly symmetrical construction element (25) is conjugated, which, for example, it is developed in the form of an annular disc and exhibits a coating (26), in the direction of the sintered sliding bearing bushing (12) with a low surface tension in relation to the shaft material (9). Oily lubricating material dragging from the sintered sliding bearing bushing (12) is prevented from continuing to drag, by this coating (26), which for example consists of polytetrafluoroethylene, and thus kept away from the collector. This avoids operating damage to the electric motor (2).
