    摘要： A slip ring arrangement comprises a brush with a first contact material on the surface, which rests on a slideway with a second contact material on the surface. The slideway further comprises a layer with a third contact material beneath the second contact material. In this case, the abrasion of the brush is lower than that of the second contact material in the case of a sliding contact between the brush and the second contact material. In the case of a sliding contact between the brush and third contact material, the abrasion of the brush is higher than that of third contact material. As a result, the second contact material of the slideway is degraded first, which corresponds to the normal service life of a slideway. Subsequently, the brush is worn off relative to the third contact material, by means of which a further considerable extension in the service life is achieved.

    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 present invention is aimed at providing a sliding contact material that has an alloy composition containing no harmful substance like Cd, especially excellent contact resistance properties, electrical functions that are good and is not subject to secular change, and abrasion resistance practically bearing comparison with conventional sliding contact materials, and is aimed at lengthening the life of a motor by the use of a sliding contact material having excellent durability as a commutator for a small direct-current motor. The present invention is a sliding contact material of an AgnullNi-based alloy that is used in sliding part electrically switching on and off by mechanical sliding action, and the material is a sliding contact material of Ni metal particle-dispersed-type AgnullNi-based alloy that is produced in such a method that 0.7 to 3.0 wt. % Ni powder, an additive of Li2CO3 powder corresponding to 0.01 to 0.50 wt. % Li after being converted to metal and the balance of Ag powder are mixed and stirred to form a uniformly dispersed mixture, then the mixture is treated with forming and sintering processes.
