Abstract
The invention relates to a disk blank (18) for producing commutator bars of a disk commutator as well as to a commutator bar and a disk commutator realized as having such commutator bars, said disk blank (18) being realized as a multi-layered body and having a carbon mold body having a continuous first layer and having a contact arrangement which forms a second layer disrupted by transition areas in such a manner that the transition areas do not comprise any contact material.
Claims13
A disk blank (18, 26) for producing commutator bars (12, 37) of a disk commutator (10), comprising a carbon mold body (22, 27) made of carbon material for forming tread segments (13, 38) of the commutator bars and comprising a contact arrangement (24, 28) made of a carbon and arranged on the carbon mold body (22, 27) and comprising a contact material having contact metal for forming connecting segments of the commutator bars,
- characterized in that
- the contact arrangement comprises contact bodies (16, 31) spaced apart from each other via transition areas (21), said contact bodies (16, 31) being realized as contact-material mold bodies and being connected to the carbon mold body (22, 27) in a compression molding method in such a manner that the disk blank (18, 26) is realized as a multi-layered body, said carbon mold body (22, 27) forming a continuous first layer and said contact arrangement forming a second layer disrupted by the transition areas in such a manner that the transition areas do not comprise any contact material.
