Brush holder for commutating machines

Abstract

A brush holder for commutator machines is disclosed, which has a plurality of commutator brushes (15), embodied for nonpositive assembly on a commutator (18) of the commutator machine, each of which brushes is guided axially displaceably with play in a brush quiver (12) and is urged in the expulsion direction from the brush quiver (12) by a brush compression spring (16) that is braced between the brush quiver (12) and the commutator brush (15). In each brush quiver (12), a restraining member (21) is provided as an assembly aid, which restrains the spring-loaded commutator brush (16) in the assembly by positive engagement on the brush quiver (12) and releases it after the assembly. To achieve an assembly aid that is very simple to produce and saves assembly time, the restraining member (20) is an integral part of the brush quiver (12) and is embodied such that the positive engagement can be generated by slightly tilting the commutator brush (15) in the brush quiver (12) and can be undone again by straightening it (FIG. 4).
