Abstract
Official abstract text for this publication.
A connection element providing a first ring and a second ring, the two rings rotating relative to one another about a central axis, the first ring having a contact portion with a contact surface interacting with the second ring for the relative rotation, and a fastening portion configured to be rigidly secured to a support. The contact portion is made of a first material and the fastening portion is made of a second material, different to the first material, the first material having a hardness strictly greater than that of the second material, and the second material having a structural fatigue strength strictly greater than that of the first material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A connection element comprising: a first ring comprising a contact portion and a squirrel cage, the contact portion having a contact surface, the squirrel cage having a fastening portion intended to be rigidly secured to a support, a second ring, the two rings rotating relative to one another about a central axis, the contact surface and the second ring being configured for placement of a plurality of roller elements therebetween wherein the contact portion is made of a first material and the squirrel cage is made of a second material, different to the first material, the first material having a hardness strictly greater than that of the second material, and the second material having a structural fatigue strength strictly greater than that of the first material, and the squirrel cage and the fastening portion of the first ring do not axially overlap the second ring. 2. The connection element according to claim 1 , further comprises the plurality of roller elements disposed between the contact surface of the contact portion of the first ring and a second contact surface of the second ring. 3. The connection element according to claim 2 , wherein the first material is one out of the following list: 100C6, high speed steel M50, ASP 2060 or M62. 4. The connection element according to claim 2 , wherein the second material is one out of the following list: low carbon steel, medium carbon steel, titanium alloy, aluminium alloy, M50NiL, 32CVD13, INCONEL718. 5. The connection element according to claim 1 , wherein the squirrel cage comprises a radial fastening rim and an essentially axial portion with a plurality of windows distributed circumferentially.
