Patent ID: 7771123

Claim:
Connection device for connecting a contact rolling bearing to an external body, the bearing having a rotation axis, and comprising two races which are co-axial in relation to each other and in relation to the rotation axis, the connection device comprising a peripheral connecting outline, which is circumferentially obtained along an inner first race of said two races, and a complementary connecting outline, which is circumferentially obtained along the external body, and which has a shape complementary to the peripheral connecting outline in order to render angularly integral in relation to each other the external body and the first race; wherein the peripheral connecting outline and the complementary connecting outline both have a continuous radius of angularly variable dimensions on a plane which is transverse to the rotation axis, wherein the peripheral connecting outline and the complementary connecting outline taper in relation to the rotation axis, and both comprise, in relation to the rotation axis, at least one respective convex portion wherein the external body is defined by a brake disk including an internal housing; wherein said complementary connecting outline radially delimits towards the internal housing; axial blocking means arranged axially outside the first race, the axial blocking means being associated with the first race to force the external body onto the first race.
