Publication number: 20230158598Abstract: The disclosed technology relates generally to welding technologies and more particularly to electrode assemblies for arc welding, e.g., submerged arc welding. In one aspect, an electrode assembly for submerged arc welding (SAW) comprises a head portion and an extension portion that are arranged serially to feed a consumable electrode therethrough such that, during SAW, the head portion is disposed to be distal to an arcing tip of the consumable electrode and the extension portion is disposed to be proximal to the arcing tip of the consumable electrode. The head portion includes a contact tip configured to electrically contact the consumable electrode to deliver power thereto. The extension portion is formed of a single piece insulating article configured for the consumable electrode to finally pass through before the arcing tip is exposed.Type: ApplicationFiled: November 18, 2022Publication date: May 25, 2023Inventors: Romain Ravet, Yann Levillain, Yann Rivet, Laurent Longinotti, Loic Verwaerde, Telmo Agostinho, Dirk Haupt, Christoph Vollet, Jerome Cantet, Michel Jany, Christopher Thume, Frank Bolte, Roland Pollmann, Bryan M.

Publication number: 20220018396Abstract: The present disclosure relates to a sliding bearing comprising a first bearing element and a second bearing element. The first bearing element is coated in multiple layers. An inner layer is deposited on a base material of the first bearing element by means of a vapor deposition method. The inner layer has a structure, and an outer layer designed as a PTFE impregnation layer leveling the structure of the inner layer. The second bearing element is formed of PTFE fiber-reinforced plastic or has a PTFE-containing sliding lining.Type: ApplicationFiled: June 3, 2021Publication date: January 20, 2022Applicant: Schaeffler Technologies AG & Co.

Publication number: 20180149193Abstract: A spherical bearing an inner ring that can rotate and pivot with respect to an outer ring. A sliding body is placed about the inner ring and inside of the outer ring. The sliding body reduces the friction associated with the relative movement of the inner ring and outer ring. The sliding body has a concave inner surface that contacts the convex outer surface of the inner ring. The sliding body may be made of a polymer composite material to reduce the friction during movement. During assembly, the sliding body is placed about the inner ring, and then the outer ring is placed over the sliding body. To contain the sliding body, the outer ring may be bent or caulked.Type: ApplicationFiled: May 17, 2016Publication date: May 31, 2018Applicant: SCHAEFFLER TECHNOLOGIES AG & CO.
