ABSTRACT:
A device for angularly centering a member having an annular toothed formation, for example an electric motor commutator prior to mounting the commutator on a rotor shaft, comprises a centering bracket located in the path of movement of the member. The bracket has, at its upstream end, a ramp, followed by two laterally spaced centering profiles. If a tooth of the member engages the ramp, the bracket is resiliently deflected and the tooth thereafter engages one of the centering profiles. Alternatively, the tooth will directly engage the other of the centering profiles. When the member has been centered by either one of the two profiles, it is held in its centered position within a grooved seat to enable further operations to take place.
