摘要： A rolling bearing cage includes at least one cage side ring and a plurality of cage bars extending from the cage side ring so as to form a plurality of pockets, each pocket being defined between a separate pair of adjacent bars, for receiving rolling bodies of the rolling bearing. A cage breakage detection unit includes at least one conductive track and a module for wireless cage breakage monitoring. The cage has at least one recess, in which at least a prefabricated part of the cage breakage detection unit is inserted and fixed.

摘要： The present invention resides in a sensorized roller of a roller bearing. The sensorized roller includes a roller bore that accommodates a measuring device for measuring deformation of the roller bore and electronics for processing a deformation signal from the measuring device and wirelessly transmitting the processed deformation signal to an external receiver. According to the invention, the measuring device and electronics are mounted in a rigid housing that is shaped to fit within the roller bore. A radially outer surface of the housing includes at least one aperture associated with the measuring device. Furthermore, the rigid housing is resiliently mounted to the roller bore via first and second sealing elements that enclose a radial gap between a radially inner surface of the roller bore and a radially outer surface of the housing.

摘要： A roller of a roller bearing providing a hollow bore in which a load cell is arranged, for measuring a radial load acting on the roller. The load cell is mounted to the roller bore in a non-fixed manner and includes one or more cantilever beams that extend in an axial direction of the roller. A contact element is provided on each cantilever beam. Each element further bears against a surface of the roller bore. At least one sensor is provided on each cantilever beam for measuring bending thereof, due to deflection of the beam in a radial direction perpendicular to the axial direction.
