Abstract
A bearing ring having a main part ring provided with at least one groove formed a surface of the main part ring. The bearing ring further provides at least one fiber sensor mounted inside the groove. The bearing ring also include at least one counterpart ring mounted into the groove of the main part ring and coming into contact with the fiber sensor to maintain the fiber sensor against a groove bottom, the counterpart ring being secured to the main part ring.
Claims20
A bearing ring comprising:
- a main part ring provided with at least one groove formed on a surface of the main part ring,
- at least one fiber sensor mounted inside the groove, and
- at least one counterpart ring mounted into the groove of the main part ring and, when viewed in cross section, tangentially contacting the fiber sensor in order to maintain the fiber sensor against a bottom portion of the groove, the counterpart ring being secured to the main part ring.
A bearing ring comprising:
- a main part ring provided with at least one groove formed on a surface of the main part ring,
- at least one fiber sensor mounted inside the groove, and
- at least one counterpart ring mounted into the groove of the main part ring and coming into contact with the fiber sensor in order to maintain the fiber sensor against a bottom portion of the groove, the counterpart ring being secured to the main part ring, wherein
- the groove of the main part ring has a V-shaped cross-section, the counterpart ring being provided with two opposed frustoconical frontal faces each coming into contact with one of the sidewalls of the groove.
