Abstract
One or more sensors are mounted on the inside surface of a stationary race/sensor mount assembly in the bearing housing. A parameter sensed by the sensor is electronically fed to the outside surface of the stationary race/sensor mount assembly and detected by a transmitter mounted in the housing. The detected information is electrically fed from the transmitter to an electronic system located outside the housing.
Claims10
In combination:
- a housing;
- a rotatable member within said housing serving as a race;
- a stationary race/sensor mount assembly mounted in the housing having a greater inside diameter than the outside diameter of the rotatable member and serving as a raceway and having at least one sensor mount;
- a plurality of rollers located in the annular space between the rotatable member and the stationary race/sensor mount assembly;
- a sensor located on the inside surface of the sensor mount;
- electrical contacts located on the outside surface of the sensor mount, the sensor mount having a hole interconnecting the sensor and the electrical contacts;
- electric wires extending through said hole for sending electric signals from the sensor to the electrical contacts;
- a transmitter mounted in said housing, said transmitter having members therein which contact the electrical contacts located on the outside surface of the sensor mount;
- said housing having holes extending from the transmitter through the housing for receiving wires for transmitting signals from the transmitter to electronic systems located outside the housing.
