摘要： A carbonaceous material is fabricated by kneading of carbon powder and a binder. A particle diameter of the carbonaceous material is adjusted after the fabricated carbonaceous material is granulated. A brush material is fabricated by mixing of the carbonaceous material of which the particle diameter is adjusted and metal powder. A brush is completed by forming and thermal processing of the fabricated brush material. In this case, the particle diameter of the carbonaceous material is adjusted in a constant range before the carbonaceous material and the metal powder are mixed such that an average particle diameter of the carbonaceous material in the brush is not less than 300 µm and not more than 2000 µm. Alternatively, a ratio of the volume of the carbonaceous material having the particle diameter of not less than 300 µm to the volume of the brush is adjusted to not less than 50%.

摘要： The purpose of the present invention is to ensure reduction performance of radio noise while improving a workability and preventing a brush protective jig for protecting a brush contact from being forgotten to be removed, when assembling a sliding contact brush. A power transmission device for an electrically driven vehicle includes: a reduction gear mechanism (3); a sliding contact brush assembly (25); a brush case cover (16); and a protective cover (20). The reduction gear mechanism (3) is interposed between a motor (1) driven by an inverter (2) and drive wheels (9,9). The sliding contact brush assembly (25) is provided at the position of a shaft end (3c') of a countershaft (3c). The brush case cover (16) is mounted to a cover mounting portion (19). The protective cover (20) is mounted so as to cover brush contacts (5a, 5a) when the sliding contact brush assembly (25) is assembled to the shaft end (3c'). The protective cover (20) is set to have the axial length (L) interfering with the brush case cover (16), when the brush case cover (16) is mounted to the cover mounting portion (19) in a state where the protective cover (20) is installed.

摘要： Die Erfindung bezieht sich auf eine Vorrichtung und ein Verfahren zum Schließen von einer köcherförmigen eine Schließfläche (11) aufweisenden Kohlebürstenaufnahme (13) umfassend einen eine vorgebogene Kohlebürstenaufnahme aufnehmenden Passdom (52) mit einer Planierfläche (54), entlang der sich die Schließfläche bildende Abschnitte (13, 15) der Kohlebürstenaufnahme erstrecken, auf Randbereiche der Planierfläche absenkbare Biegebacken (22, 24), einen zwischen den Biegebacken entlang deren Innenflächen verlaufenden zum Schließen der Schließfläche auf die Abschnitte absenkbaren Kernbiegestempel (30) sowie entlang jeweiliger Außenfläche der Biegebacken verlaufende und mit diesen wechselwirkende Anpressschieber (56, 58), wobei die Biegebacken verschwenkbar von einem ersten Element wie Führungsplatte (27) und der Kernbiegestempel von einem zweiten Element wie Druckplatte (42, 32) ausgehen, die in Wirkverbindung miteinander verstellbar sind. Um sicherzustellen, dass bei Materialdifferenzen die fertige dem Passdom zu entnehmende Kohlebürstenaufnahme stets die gewünschten Innenmaße innerhalb eines Toleranzbereichs aufweist, wird vorgeschlagen, dass die Anpressschieber (56, 58) unabhängig von einer Bewegung des ersten und zweiten Elements (27, 32, 42) relativ zu den Biegebacken (22, 24) verstellbar sind.

摘要： The invention relates to a method and a device for manufacturing a multi-layer compression moulded element and to a compression moulded element which is embodied as a multi-layer carbon brush and has at least a first and a second moulding layer, in which, in order to carry out the method, a multi-component mould which comprises a moulding element and a mould slide arrangement interacts with a moulding die, and in which a mould which is defined by the selected configuration of the moulding slide arrangement in the moulding element is filled by filling moulding segments which are formed one next to the other with moulding material in chronological succession in a transverse direction with respect to the axis of the moulding die, and by the compression moulded element being subsequently formed by moving the moulding die and moulding slide arrangement relative to one another in the mould.

摘要： A conductive fiber brush including a brush stock (1) composed of plural conductive fibers or strands of fibers at least some of which may have plural bends along the length of the fibers or strands. The fibers may have a diameter less than 0.2 mm and are arranged in contacting engagement with each other with the touching points among the fibers or strands maintaining elastic tension between the fibers or strands and thereby maintaining voids between the fibers or strands to produce a packing fraction between 1 and 50 % and in extreme cases up to 70 % but generally between 10-20 % depending on the various factors, including the materials used, the current densities to be conducted, and the sliding speeds under operation. The plural bands are implemented by producing fibers or strands having a regular or irregular spiral, wavy, saw-tooth, triangular, and/or rectangular pattern; or other undulating pattern. Optionally, the voids in the brush stock (1) may be partially wrapped in an outer sheath (10), slid into a casing, or provided with an other covering of all or part of the area of the brush stock (1), be infiltrated or sprayed at the surface with some material, have an increased packing fraction at the surface and/or have some or all of the touching points between the fibers or strands soldered, welded or otherwise thermally joined. Optionally also, the friction among the fibers may be reduced through light lubrication applied by rinsing the brush or brush stock (1) in a lubricant. In one embodiment, the fiber brush (1) is employed in a brush loading device having a hydrostatically controlled brush holder wherein the force exerted on the brush (1) is controlled by a metallic or other conductive hydrostatic fluid which at the same time conducts the current to the brush (1).

摘要： The invention relates to a method for production of a multi-layer carbon brush (10), comprising at least two electrically-conducting functional layers (12, 14, 16) made from carbon material and at least one insulation layer made from an electrically-insulating material, running between consecutive functional layers. According to the invention, the corresponding multi-layer carbon brushes and the layers with desired thickness can be produced, whereby the carbon material and the electrically-insulating material are applied in a mould in a sequence corresponding to the layer sequence of the multi-layer carbon brush for production (10), in powder form, then pressed and finally heat-treated.
