<p>The system has a hub that rotates around a rotation axis. The hub has an outer cylindrical surface (109) of curved direction for defining a hub section. The section has apexes that separate hub lobes (123) whose concavity is turned towards the axis. Spring pins (126) are arranged at the apexes in a projecting manner with respect to the section, in contact with a cylindrical inner surface (111) of an annular unit (103). The annular unit is a homothetic image of the hub section, in a relative position of the unit and the hub.</p> |
