Abstract

A system includes a gear unit, the gear unit including at least one housing cover, a sensor unit, on which sensors are provided, being provided on the housing cover, the sensors being connected at least electrically to an evaluation unit.

Claims

1-15. -15. (canceled)

16. A system, comprising:

a gear unit including at least one housing cover; and

a sensor unit provided on the housing cover, the sensor unit including sensors connected at least electrically to an evaluation unit.

17. The system according to claim 16, wherein the gear unit includes at least one of (a) a housing and (b) a housing part, the housing cover covering a cutout in at least one of (a) the housing and (b) the housing part.

18. The system according to claim 16, wherein the sensor unit includes accommodations for the sensors.

19. The system according to claim 16, wherein the sensor unit is joined to the housing cover on a side of the housing cover facing surroundings.

20. The system according to claim 16, wherein the sensor unit is formed in one piece with the housing cover.

21. The system according to claim 16, wherein the housing cover is made of metal.

22. The system according to claim 21, wherein the sensor unit is made of at least one of (a) a metal different than the metal of the housing cover and (b) plastic.

23. The system according to claim 16, wherein the sensor unit is made of a metal for shielding.

24. The system according to claim 16, the evaluation unit is at least one of (a) connected to the sensor unit, (b) connected to the sensor unit on a side of the sensor unit facing surroundings, and (c) formed in one piece with the sensor unit.

25. The system according to claim 16, wherein at least one sensor is arranged as at least one of (a) a vibration sensor and (b) a vibration sensor adapted to detect structure-borne noise generated by at least one of (i) bearings and (ii) toothing parts.

26. The system according to claim 16, wherein at least one sensor is arranged as at least one of (a) an inductive proximity sensor and (b) an inductive proximity sensor adapted to determine rotation of a toothing part.

27. The system according to claim 16, wherein at least one sensor is arranged as at least one of (a) an oil-condition sensor and (b) an infrared oil-condition sensor adapted to determine at least one of (a) a condition and (b) an age of lubricating oil of the gear unit.

28. The system according to claim 16, wherein at least one sensor is arranged as at least one of (a) a torque sensor, (b) an OFW torque sensor, (c) a DMS torque sensor, and (d) a sensor adapted to determine torque transmitted with the aid of a shaft of the gear unit.

29. The system according to claim 16, wherein at least one sensor is arranged as an oil-level sensor.

30. The system according to claim 16, wherein at least one sensor is adapted to determine a displacement of a component of the gear unit.

31. The system according to claim 16, wherein the evaluation unit includes at least one of (a) a timing element and (b) a quartz-crystal oscillator.

32. The system according to claim 16, wherein the evaluation unit is formed in one piece with the sensor unit.

33. The system according to claim 16, wherein the evaluation unit at least one of (a) includes a display device, (b) includes at least one interface, and (c) is arranged as a node of a bus system.

34. The system according to claim 16, wherein the housing cover includes a cutout for a sensor.
