ABSTRACT:
A current-conducting bearing or contact bearing includes contact-making surfaces of a bearing bolt and a shaft fashioned as an axial cone and a hollow cone, respectively. With a suitable choice of materials of the current conducting parts, such as special bronzes, an allowable current load of up to 200 amperes per square cm is possible, compared to 4 amperes per square cm in the case of hard carbon and 25-30 amperes per square cm in the case of bronze carbon of traditional brushes in slip rings of electric machines.
