Abstract
The present invention defines 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.
Claims13
A roller for a roller bearing comprising:
- a hollow bore in which a load cell is arranged, wherein
- the load cell is mounted to the roller bore in a non-fixed manner and provides one or more cantilever beams that extend in an axial direction (z) of the roller,
- a contact element is provided on each cantilever beam, the contact element bears against a surface of the roller bore;
- and
- at least one sensor is provided on each cantilever beam for measuring bending thereof, due to deflection of the beam in a radial direction (r) perpendicular to the axial direction (z).
A bearing comprising:
- a roller having a hollow bore into which a load cell is arranged, wherein
- the load cell is mounted to the roller bore in a non-fixed manner and provides one or more cantilever beams that extend in an axial direction (z) of the roller,
- a contact element is provided on each cantilever beam, the contact element bears against a surface of the roller bore;
- and
- at least one sensor is provided on each cantilever beam for measuring bending thereof, due to deflection of the beam in a radial direction (r) perpendicular to the axial direction (z).
