Patent number: 9228615Abstract: An articulated spindle (3) which is arranged in particular in a drive of a rolling mill, comprises a coupling sleeve for establishing a connection to an articulated head, or an articulated head (4) for establishing a connection to a coupling sleeve (2), wherein the tongue (1) of the coupling sleeve (2) engages with a cylindrical opening (5) of the articulated head (4) that is located transverse to the rotational axis. A sliding block (19) is arranged between the articulated head and the tongue (1), said block being formed by two sliding bodies (21, 22), which have rotational body contours (23, 24) in two portions, said sliding bodies being arranged rotatably in a rotational body-shaped recess (25, 31) adjusted to the shape of the sliding bodies (21, 22) such that they can perform a pivoting motion in the articulated head (4).Type: GrantFiled: November 12, 2010Date of Patent: January 5, 2016Assignee: SMS GROUP GMBHInventors: Rüdiger Grimmel, Christoph Sundermann, Ralf Gehle

Patent number: 8820699Abstract: A torque support for a converter tilting drive mounted on a shaft journal. The supports are provided on the gear housing that accommodates the shaft journal to be driven. The supports support the gear housing on the structure carrying the converter. To this end, the supports are embodied in each case as dual action hydraulic piston-cylinder units that are independently anchored on the structure in an articulated manner.Type: GrantFiled: May 8, 2009Date of Patent: September 2, 2014Assignee: SMS Siemag AGInventors: Jörg Hertel, Benjamin Wallmeroth, Lutz Rose, Christoph Sundermann, Stephan Schulze, Christian Imiela, Wolfgang Igelhorst, Uwe Thiedemann

Patent number: 8109168Abstract: The invention relates to a converter gearing, comprising a gear rim (7), which is connected to the pivoting axis (6) of a converter box, said gear rim being engaged with at least one drive pinion (8) of the converter gearing (9) and at least one locking device, which can be pivoted to engage with and be disengaged from the toothed gearing of the gear rim, (7) in the form of a locking arm (12) that is positioned on a horizontal shaft (10) and configured with toothed gearing (11). The aim of the invention is to improve said locking device. To achieve this, the shaft (10) of the locking arm (12) is mounted in at least one terminal bearing (13, 13?) and the locking arm (12) can be engaged with and disengaged from the toothed gearing of the gear rim (7) in a non-positive manner, preferably by means of active force elements (14, 14?) in its end regions.Type: GrantFiled: August 28, 2002Date of Patent: February 7, 2012Assignee: SMS Siemag AktiengesellschaftInventors: Gerhard Wurm, Christoph Sundermann, Rüdiger Grimmel

Publication number: 20110289995Abstract: The invention relates to a car (100) for transporting at least one drive spindle for a roller of a roll stand (300) and to a method for operating the car. The car comprises a running unit (105) for displacing the car from the operating side of the roll stand, through the roll stand, to the drive side, or vice versa, and the car is built flat enough that it fits under the drive spindles. The car according to the invention is an alternative to the prior art. Said car is designed as a lift car having a first carrier device (110) and a first drive unit (120), wherein the first drive unit (120) serves for raising or lowering the first carrier device (110), optionally having the drive spindle (200), relative to a neutral position.Type: ApplicationFiled: August 17, 2009Publication date: December 1, 2011Applicant: SMS SIEMAG AKTIENGESELLSCHAFTInventors: Eckehard Jung, Rüdiger Grimmel, Nikolas Münchow, Christoph Sundermann

Publication number: 20110227334Abstract: The invention relates to a rotary union for supplying and/or discharging a medium under pressure into or out of an axial cavity of a rotating machine part, comprising a union part (12), which does not rotate and is fixed relative to the device, a rotary union part (15) and with bearing means as well as sealing components, which act in a radial sealing plane between the rotary union part (15) and the union part (12) fixed relative to the device. The rotary union is characterized in that the bearing means comprise individual step bearings (13, 14), which fix the radial distance between the union part (12) fixed relative to the device and the rotary union part (15).Type: ApplicationFiled: November 12, 2009Publication date: September 22, 2011Applicant: SMS SIEMAG AKTIENGESELLSCHAFTInventors: Rudiger Grimmel, Christoph Sundermann, Uwe Berkholz
