Abstract

a. L'invention concerne une machine électrique, notamment alternateur triphasé pour véhicules automobiles, comportant un carter de machine, un stator, un rotor et un arbre de rotor et des paliers pour servir de paliers à l'arbre de rotor dans le carter de la machine, un premier palier étant bloqué rigidement en direction axiale et le deuxieme palier pouvant coulisser axialement b. Cette machine est caractérisée en ce que le deuxième palier 17 est agencé sous forme de palier à billes et comporte une bague intérieure cylindrique 32. c. L'invention est applicable notamment aux alternateurs triphasés pour véhicules automobiles.at. The invention relates to an electric machine, in particular a three-phase alternator for motor vehicles, comprising a machine housing, a stator, a rotor and a rotor shaft and bearings for acting as bearings for the rotor shaft in the machine housing. , a first bearing being rigidly blocked in the axial direction and the second bearing being able to slide axially b. This machine is characterized in that the second bearing 17 is arranged in the form of a ball bearing and comprises a cylindrical inner ring 32. c. The invention is particularly applicable to three-phase alternators for motor vehicles.
