Abstract
A sensorized bearing ring includes a metallic ring member having a core, the core having a radially outer surface and a radial inner surface, and a layer of metal on the radially inner surface or on the radially outer surface. The layer of metal is a laser metal deposition layer that has a hardness greater than a hardness of the core. At least one groove extends into the core, a sensor member is mounted in the groove and the groove is sealed. Also an associated method.
Claims17
A sensorized bearing ring comprising:
- a metallic ring member having a core, the core having a radially outer surface and a radial inner surface,
- a layer of metal on the radially inner surface or on the radially outer surface, the layer of metal comprising a laser metal deposition layer,
- wherein a hardness of the core is less than a hardness of the laser metal deposition layer, wherein at least one groove extends into the core,
- wherein a sensor member is mounted in the groove, and
- wherein the groove is sealed.
A method for manufacturing a sensorized bearing ring comprising:
- providing a metallic ring member having a core, the core having a radially outer surface and a radial inner surface and a layer of metal on the radially inner surface or on the radially outer surface, the layer of metal comprising a laser metal deposition layer, and a hardness of the core being less than a hardness of the laser metal deposition layer,
- forming a groove through the layer of metal and into the core,
- mounting at least one sensor member in the groove;
- and
- sealing the groove.
A method for manufacturing a sensorized bearing ring comprising:
- providing a metallic ring member comprising a core;
- forming a groove in a first radially facing surface of the ring member;
- mounting at least one sensor member in the groove;
- and
- depositing by laser metal deposition a laser metal deposition layer on the first radially facing surface of the ring member,
- wherein a hardness of the metal of the laser metal deposition layer is harder than a hardness of the core.
