Abstract

A gear is provided that includes a gear surface with a vibration sensor. The vibration sensor further includes an accelerometer coupled to a data transmitter and the vibration sensor is provided within a cavity in the gear surface.

Claims

1. A gear comprising:

a gear surface with a vibration sensor (12), the vibration sensor having an accelerometer coupled to a data transmitter, wherein

the vibration sensor is provided within a cavity in the gear surface.

2. The gear as claimed in claim 1, wherein a surface of the cavity functions as a sensor well for comprising the accelerometer and the data transmitter.

3. The gear as claimed in claim 1, wherein the cavity is at least partly filled with potting material for sealing the vibration sensor.

4. The gear as claimed in claim 1, wherein the accelerometer and the data transmitter are mounted on a printed circuit board.

5. The gear as claimed in claim 4, wherein the printed circuit board is attached to a surface of the cavity.

6. The gear as claimed in claim 5, wherein the printed circuit board is attached to the surface of the cavity via metal or plastic spacers.

7. The gear as claimed in claim 1, wherein the vibration sensor further comprises an electric power source for providing electrical power.

8. The gear as claimed in claim 1, wherein the electric power source is arranged for deriving power from electrical signals coming from the accelerometer.

9. The gear as claimed in claim 1, wherein the gear surface further comprises at least one additional cavity for providing an additional vibration sensor.
