Patent number: 8500336Abstract: Guide roller rotating bearing for a metal melt bath includes pivot arms and a roller bearing device arranged on each of the pivot arms. The roller bearing device includes an outer ring, cylindrical rollers and an inner ring. The outer ring includes first and second outer ring flange members. The outer ring is fixed to a pivot arm. The cylindrical rollers are configured as rolling elements. The inner ring has first and second inner ring flange members. The first and second outer ring flange members and the first and second inner ring flange members are configured to fix the cylindrical rollers in an axial direction. A shaft end includes a protective covering disposed in the roller bearing device. The protective covering includes a protective covering material that exhibits a wear-resistance which is higher than a wear resistance of the shaft end.Type: GrantFiled: August 27, 2009Date of Patent: August 6, 2013Assignee: Band Zink GmbHInventors: Alireza Kouscheschi, Roman Lieutenant, Wilfried Plaetzer, Daniel Plaetzer

Patent number: 7175711Abstract: A coating device (10) for coating a metal strip (12) in a metal melt (14) includes a shaft (16,18) that is rotatable in the metal melt (14) for guiding the metal strip (12), and a slide bearing (261, 262) for supporting the shaft (16,18). The slide bearing (261, 262) is formed by a bearing housing (32) and a bearing bushing (34) that has several pairs (361–364) of bearing surfaces and is configured so as to be circumferentially closed. The bearing bushing (34) is adapted to be set in selected rotational positions in circumferential direction in the bearing housing (32). A releasable bearing bushing fixing element (40) locks the bushing in each of the selected rotational positions with respect to the bearing housing (32). Thereby, a worn pair (361–364) of bearing surfaces can be simply replaced by a non-worn pair (361–364) of bearing surfaces by a rotation of the bearing bushing.Type: GrantFiled: June 14, 2003Date of Patent: February 13, 2007Assignee: Band-Zink GmbHInventor: Wilfried Plätzer

Patent number: 7156920Abstract: The coating device (10) for coating a metal band or strip (12, 12?) in a melted metal mass (14 ) comprises a shaft (16, 18) rotatably supported in the melted metal mass (14) by a slide bearing (261, 262) is formed by a bearing housing (32) and an open bearing shell (34) held therein, with two bearing surfaces (36) . Between the two bearing surfaces (36), the bearing shell (34) comprises a deformation zone (40) with a deformation element (44) . With high radial forces of the shaft occurring, the two bearing shell halves (381, 382) are slightly spread. The flexible deformation zone ensures that the two bearing shell halves remain interconnected and resist breaking in this area.Type: GrantFiled: June 14, 2002Date of Patent: January 2, 2007Assignee: Band-Zink GmbHInventors: Daniel Plaetzer, Wilfried Plaetzer, Ernst-Werner Schmidt, Roman Lieutenant

Publication number: 20050208226Abstract: A coating device (10) coats a metal strip (12) in a melting (14) of a coating metal. For guiding and deviating the metal strip (12), a guiding device (16) is arranged in the melting (14). The guiding device (16) is configured as a magnetic guide with at least one electric guide magnet for the contactless guidance of the metal strip in the melting (14). Thereby, the use of rolls, shafts etc. for guiding the metal strip is avoided so that the coating of the metal strip (12) with the coating metal is of a better quality and has the same quality on both sides of the metal strip (12).Type: ApplicationFiled: May 8, 2003Publication date: September 22, 2005Applicant: BAND-ZINK GmbHInventors: Wilfried Platzer, Ernst-Werner Schmidt, Alireza Kouscheschi, P.

Patent number: 6926773Abstract: The coating device for coating a metal band (12) in a melt (14) of a non-magnetic metal comprises a shaft (16) rotatable in the melt (14) for guiding the metal band (12). The shaft (16) is supported in a shaft bearing (261) that is a magnetic bearing whose stationary portion (281) is encapsulated. Thus, a contactless shaft support in a metal melt is obtained, whereby the bearing wear is largely reduced and the service life of the bearing is prolonged.Type: GrantFiled: March 28, 2001Date of Patent: August 9, 2005Assignee: Band-Zink GmbHInventor: Wilfried Plaetzer
