ROLLING BEARING DEVICE COMPRISING AN INTEGRATED SENSOR SYSTEM

摘要

The invention relates to a rolling bearing device comprising a first bearing ring, a second bearing ring, rolling bodies received in a pathway region defined between said two bearing rings, 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 aim of the invention is to create a rolling bearing device comprising an integrated sensor system, that can be economically produced in terms of production engineering and can be integrated into a corresponding mechanism with a high level of constructive freedom. To this end, the inventive rolling bearing device is provided with a first bearing ring, a second bearing ring, rolling bodies which are received in a pathway region defined between said 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. Said rolling bearing device is characterised in that 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. In this way, it is advantageously possible to create rolling bearing devices having an integrated sensor system and outer dimensions which correspond essentially to the standard outer dimensions for such rolling bearing devices. Especially advantageously, standard rolling bearings can be modified to fom inventive rolling bearings by the simple replacement of the bearing sealing ring.
