Patent number: 10110088Abstract: In a method for monitoring a state of a safety bearing of a rotor shaft of a machine, with the rotor shaft being supported by a magnetic bearing and the safety bearing having an outer ring and an inner ring arranged for rotation with respect to the outer ring, the rotor shaft of the machine is caught with the safety bearing when the magnetic bearing of the machine fails. The magnetic bearing is witched off for monitoring the state of the safety bearing. The rotor shaft is rotated with the machine under control of a higher-ranking controller by using a defined motion sequence, and a physical variable of the safety bearing is measured with a sensor.Type: GrantFiled: February 2, 2016Date of Patent: October 23, 2018Assignee: Siemens AktiengesellschaftInventors: Hartmut Walter, Jan Georgi

Patent number: 8376615Abstract: A pivot bearing having a first bearing surface of hollow cylindrical design, at least in sections. Guided in the first bearing surface is a second bearing surface of hollow cylindrical design, at least in sections. Rolling bodies are arranged between the bearing surfaces. The pivot bearing also has a cage for guiding the rolling bodies, and a slide block to prevent the cage from slipping. A first grove is formed in the first bearing surface and a second grove is formed in the second bearing surface. The groves are inclined transversely with respect to the running direction of the rolling bodies. The opposite inclination of the groves has the result that, if the spacing between the bearing surfaces is neglected, the grooves intersect. The sliding block is guided between the grooves. The cage has a recess that holds the sliding block permitting cage control.Type: GrantFiled: December 12, 2008Date of Patent: February 19, 2013Assignee: Schaeffler Technologies AG & Co.

Patent number: 8342754Abstract: A rolling bearing, which has a shoulder loose or separately mounted shoulder ring aiding assembly capacity in defined structural forms of rolling bearings or which adjusts axial play of rolling bodies in a targeted manner by adapting the separate shoulder rings. A rolling bearing, which has a first and second bearing ring and a plurality of rolling bodies. The bearing rings being are arranged in relation to each other by the rolling bodies such that they can rotate about a common axis. A shoulder body forms an edge for axial arrangement of the rolling body and lies on a front ring supporting surface of one of the bearing rings by a front shoulder supporting surface. The shoulder supporting surface and the ring supporting surface are designed such that the axial position of the edge is modified in the event of a mutual rotation of the shoulder body and bearing ring.Type: GrantFiled: April 16, 2008Date of Patent: January 1, 2013Assignee: Schaeffler Technologies AG & Co.

Publication number: 20120126648Abstract: The invention relates to a method for monitoring the state of a safety bearing (14) of a machine (12), wherein the safety bearing (14) catches a rotor shaft (1) of the machine (12) in case of failure of a magnetic bearing (6) of the machine (12), wherein the safety bearing (14) has an outer ring (3) and an inner ring (2) that is arranged rotatably in relation to the outer ring (3), wherein the magnetic bearing (6) is switched off, wherein the rotor shaft (1) is rotationally moved with a defined course of movement, wherein a physical variable (G) of the safety bearing (14) is measured by means of a sensor (5). The invention further relates to a corresponding machine. The invention allows for monitoring the state of a safety bearing (14) installed in a machine (12).Type: ApplicationFiled: April 16, 2010Publication date: May 24, 2012Applicants: SCHAEFFLER TECHNOLOGIES GMBH & CO.

Publication number: 20080285906Abstract: The invention relates to a bearing set for a shaft to be guided in an axially restricted and exact manner, a running wheel or the like for machine units. The aim of the invention is to devise less expensive bearings for receiving comparatively low axial back pressure forces. The bearing set consists of an angular ball baring receiving axial pressure forces due to operation, and a cylinder roller bearing configured as a support bearing and receiving axial back pressure forces.Type: ApplicationFiled: November 14, 2006Publication date: November 20, 2008Applicant: SCHAEFFLER KGInventors: Jan Georgi, Rainer Moller
