Abstract
A bearing which includes a bearing ring and rolling elements. The bearing ring includes an outer surface, having a groove around a circumference of the outer surface, wherein the groove is adapted to accommodate a fiber sensor. The bearing further comprises a clamping element, wherein the clamping element retains the fiber sensor with a clamping force acting in a radial direction of the bearing ring such that the fiber sensor intimately engages the bearing ring. Due to the clamping force, relative movement of the fiber sensor can be reduced.
Claims15
A bearing comprising:
- a bearing ring supporting a plurality of rolling elements, the bearing ring comprising an outer surface;
- a groove around a circumference of the outer surface, wherein the groove accommodates a fiber sensor;
- and
- a clamping element, wherein the clamping element engages the fiber sensor with a clamping force acting in a radial direction of the bearing ring such that the fiber sensor intimately engages the bearing ring.
A method for connecting a fiber sensor to a bearing, the bearing comprising a bearing ring and rolling elements, whereby the bearing ring comprises an outer surface, the method comprising steps of:
- providing a groove along at least part of a circumference of the outer surface of the bearing ring, the groove having a width dimension parallel to an axial direction of the bearing ring and a depth dimension parallel to a radial direction of the bearing ring,
- inserting a fiber sensor into at least part of the groove,
- mechanically clamping the fiber sensor within the groove, such that the fiber sensor intimately engages the bearing ring with a clamping force over that part of the groove in which it is inserted.
