METHOD FOR ASSEMBLING A COMMUTATOR ONTO THE SHAFT OF A ROTOR AND COMMUTATOR, SHAFT, ROTOR ELECTRIC MACHINE FOR IMPLEMENTING THIS METHOD

A method of force-fitting a commutator (3) onto the shaft (2) of a rotor. This force-fitting is over an externally knurled part (6) of one end (4) of the shaft. The force-fitting is performed in such a way that the externally knurled part remains located on the outside of a first portion (A) of the...

Zusammenfassung:	A method of force-fitting a commutator (3) onto the shaft (2) of a rotor. This force-fitting is over an externally knurled part (6) of one end (4) of the shaft. The force-fitting is performed in such a way that the externally knurled part remains located on the outside of a first portion (A) of the commutator supporting the slip rings (8). According to another feature, an internally knurled part (9) of the commutator, situated essentially on the outside of the first portion (A), is force-fitted over an externally plain part (7) of the end of the shaft. The method has the notable advantage of allowing longer brush life. The method is particularly well suited to applications to a motor vehicle alternator or alternator-starter.
