摘要:
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.

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.

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.

A bearing arrangement for mounting a shaft on a connection structure, the arrangement including a housing (1), a bearing which supports the shaft, and a backup bearing which includes a bearing ring that makes contact with the housing (1). According to the invention, the problem of providing a bearing arrangement which includes a backup bearing and allows the forces which arise in a loaded state to be better absorbed in the backup bearing, is solved by a slit (9) being provided in the housing (1), this slit being designed as an opening and extending substantially in a circumferential direction.
摘要:
A sealing element for a bearing, in particular a rolling contact bearing, and to a bearing, in particular a rolling contact bearing. The sealing element has a sealing composed of an elastic material, at least one support element composed of a rigid material, an IC identification, and an antenna for the IC identification. The at least one support element is formed from a non-metallic material such that the sealing element remains sufficiently stable mechanically and the operation of the antenna suffers little interference.

A bearing device having a bearing which rotatably supports a shaft, and a safety bearing (1) which receives the shaft in the event of a failure of the bearing. The aim of extending the service life of the safety bearing in the bearing device described above is achieved according to the invention in that a bearing race (2) of the safety bearing (1) facing the shaft comprises a lateral surface (3) having a convex contour (4) facing toward the shaft.
摘要:
A bearing arrangement for the rotatable mounting of a shaft (7) in relation to a housing (8), including a back-up bearing (9) which is designed as a rolling bearing, wherein the rolling bearing can absorb forces in the axial and radial direction and is designed in particular as an angular rolling bearing, especially as a two-row angular ball bearing, wherein the rolling bearing (9) is substantially free in the radial direction. The problem addressed by the invention is that of providing a bearing arrangement with a back-up bearing for a shaft, which bearing arrangement can better absorb in particular the forces occurring in the mounting of rapidly rotating, solid shafts.
