Abstract (en)
[origin: EP0350855A2] In a commutator (1) for electrical machines, the segments (2) of which form at least one seat for a prestressed reinforcing ring (7) concentric to the longitudinal axis of the commutator, the material section (6) of the segments (2) delimiting the seat with respect to the longitudinal axis of the commutator is plastically deformed outwards in radial direction. During the plastic deformation, the segments (2) are supported from the outside. The widening of the seat leads to a widening of the reinforcing ring (7), from which the tensioning thereof results. <IMAGE>
