20100043570 | SHAFT ARRANGEMENT HAVING A ROLLING BEARING - 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. | 02-25-2010 |
20100172605 | ROLLING BEARING DEVICE COMPRISING AN INTEGRATED SENSOR SYSTEM - A rolling bearing device, which has a first bearing ring, a second bearing ring, rolling bodies in a pathway region that is defined between the two bearing rings, a cage device for separating the rolling bodies, and a sensor system for generating a sensor signal relating to the relative rotation of the inner ring in relation to the outer ring. The sensor system is embodied in such a way that the sensor signal is collected on the basis of an interaction effect between a signal tapping element and a structure rotating with the cage device. Thus, it is advantageously possible to create rolling bearing devices which have an integrated sensor system and outer dimensions which correspond essentially to the standard outer dimensions for such rolling bearing devices. Moreover, standard rolling bearings can be modified to form inventive rolling bearings by replacement of the bearing sealing ring. | 07-08-2010 |
20100283208 | SEALING ELEMENT FOR A BEARING, IN PARTICULAR A ROLLING CONTACT BEARING - The invention relates to a sealing element for a bearing, in particular a rolling contact bearing, and to a bearing, in particular a rolling contact bearing, wherein the sealing element comprises a sealing means ( | 11-11-2010 |
20100305879 | DRIVE DEVICE COMPRISING A DRIVE SHAFT AND A DEVICE FOR DETECTING TORQUE - 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. | 12-02-2010 |
20110006760 | BOTTOM BRACKET WITH A TORQUE SENSOR - A bottom bracket with a torque sensor unit. The bottom bracket has at least one pedal crank, a shaft that is non-rotatably connected to the at least one pedal crank, and a torque detection device for detecting a torque in the region of the shaft. The torque detection device has a first magnetization and a sensor which detects a change of the first magnetized due to a torque passed into the shaft. The bottom bracket allows a reliable and fast detection of torques, especially of the different torques of both pedal cranks. Utilizing the shaft, which is designed as a hollow shaft and the first magnetization, which is arranged on at least one section of the shaft. | 01-13-2011 |
20110007994 | Segment rolling bearing, and axial hydraulic pump having the segment rolling bearing - A segment rolling bearing for an axial hydraulic pump, which can be integrated in a simple way. The segment rolling bearing has an outer raceway carrier, an inner raceway carrier, a plurality of rolling bodies, and a cage. The rolling bodies are arranged in the cage such that they roll between the outer raceway carrier and the inner raceway carrier in such a way that the outer raceway carrier can be pivoted about a common pivot axis with respect to the inner raceway carrier. The cage is connected to the inner and/or to the outer raceway carrier directly and captively in at least one connecting region, at least in the radial direction with respect to the common pivot axis. | 01-13-2011 |
20110239815 | DRIVE DEVICE COMPRISING A DRIVE SHAFT AND DRIVING CRANKS - A drive device for a machine, which has a drive shaft that can be rotated about an axis, and two driving cranks which are connected to the shaft in an angularly rigid manner in relation to the axis thereof. In order to determine the torque applied to the drive shaft in a simple and economical manner, the drive device has at least one magnetostrictive body connected to the driving cranks in a fixed manner, and a magnetic field sensor for measuring the magnetic stray field of the magnetostrictive body. | 10-06-2011 |
20120006128 | SHAFT ARRANGEMENT HAVING A ROLLING BEARING - 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. | 01-12-2012 |
