The toothed-rotor shaft (3) has a front end with a radially larger-sized section (32), two knurled regions (150, 156) known as crimping regions, intended to be assembled with the toothed rotor by local deformation of the material of the toothed rotor, and a centring region (54) for centring the toothed rotor, the crimping regions (150, 156) being positioned on each side of the centring region (54) while the centring region (54) projects radially with respect to the crimping regions (150, 156 - 250, 256) of the shaft (3), these themselves projecting radially with respect to the section of larger radial size at the front end of the shaft. The toothed rotor is characterized in that it is equipped with such a shaft (3) while the rotary electrical machine is characterized in that it is equipped with such a rotor. |
