Patent number: 8689643Abstract: A shaft arrangement, with a rotatable shaft supported in a rolling bearing, which has rolling elements and an outer race, a torsion sensor having a permanently magnetic ring and at least one magnetic field sensor fastened to a fixed sensor bracket attached to the outer race being provided. A torsion sensor can hereby be integrated in a rotating bearing in a simple design.Type: GrantFiled: September 14, 2011Date of Patent: April 8, 2014Assignee: Schaeffler Technologies AG & Co. KGInventors: Harald Grab, Michael Pausch

Patent number: 8330455Abstract: A sensor arrangement for a shaft that is mounted in a magnetic bearing. The arrangement has magnetic shielding which shields the magnetic bearing by forming a magnetically shielded area, magnetic encoding that is situated on the shaft in the magnetically shielded area and at least one receiver that detects at least one alteration of the magnetic field of the magnetic encoding. The aforementioned sensor arrangement for a shaft that is mounted in a magnetic bearing permits the an arrangement of this type that uses magnetic encoding of the shaft to detect the position of the shaft in the closest proximity possible to the magnetic bearing.Type: GrantFiled: September 3, 2008Date of Patent: December 11, 2012Assignee: Schaeffler Technologies AG & Co. KGInventors: Carsten Duppe, Harald Grab

Patent number: 8316709Abstract: A method and device for measuring force, torque and output on an ergometer or bicycle. When the ergometer or bicycle is used as intended, a torque is transmitted via a shaft onto a flexible drive and further onto the flywheel of an ergometer or the rear wheel of the bicycle by two pedal cranks. The flexible drive has a pulley or a sprocket wheel which is non-rotatably connected to the shaft in at least one direction of rotation. Elastic torsions of the shaft that result independently from the torque transmission are detected at both sides of the pulley or of the sprocket wheel as a measure of the forces applied to the shaft to determine the torque and output both of the left and right leg of the user of the ergometer or bicycle. Corresponding electrical sensor signals are generated and supplied to a memory and/or evaluation unit for further processing.Type: GrantFiled: July 24, 2008Date of Patent: November 27, 2012Assignee: Schaeffler Technologies AG & Co. KGInventor: Harald Grab

Patent number: 8170811Abstract: A drive device, which has a drive shaft mounted in such a way as to rotate about an axis, two driving cranks which are connected to the drive shaft in an angularly rigid manner in relation to the axis in the peripheral direction, and an output element which is connected to the drive shaft and transmits torque between the drive shaft and a load element. To enable the measurement of the torque transmitted by the shaft as easily and economically as possible, the drive device has at least one magnetostrictive sensor which is connected to the drive shaft in a fixed manner and axially arranged between a driving crank and the output element.Type: GrantFiled: May 8, 2008Date of Patent: May 1, 2012Assignee: Schaeffler KGInventors: Harald Grab, Michael Pausch
