Abstract

A hydraulic component includes a camera integrated such that the camera observes at least one surface that is prone to wear and/or at least one edge that is prone to wear to make a statement about wear relating to the at least one surface and/or the at least one edge.

First claim

The invention claimed is:

1. A hydraulic component comprising:
at least one camera integrated in the hydraulic component, the at least one camera configured such that al at least one surface that is prone to wear and is located within a housing of the hydraulic component is observable using the camera and/or (ii) at least one edge that is prone to wear and is located within the housing is observable using the camera.

2. The hydraulic component according to claim 1 , further comprising:
an evaluation unit configured to evaluate an image of the camera and to make a first statement about wear relating to the at least one surface and/or the at least one edge.

3. The hydraulic component according to claim 2 , wherein the evaluation unit includes and/or is connected to a screen so as to enable data from the evaluation unit to be evaluated by a person.

4. The hydraulic component according to claim 2 , wherein the evaluation unit includes an automated image evaluation unit.

5. The hydraulic component according to claim 2 , further comprising:
at least one sensor configured to determine operating data of the hydraulic component,
wherein the evaluation unit is configured to effect a second statement about wear relating to the hydraulic component based on the operating data.

6. The hydraulic component according to claim 5 , wherein the evaluation unit is configured to compare the second statement about wear that is based on the operating data to the first statement about wear that is based on the image.

7. The hydraulic component according to claim 1 , wherein at least one of the hydraulic component and the camera includes at least one light source that illuminates the at least one edge and/or the at least one surface within the housing.

8. The hydraulic component according to claim 7 , further comprising:
at least one cutout formed in the housing, the at least one cutout configured to accommodate at least one of the camera and the light source.

9. A hydraulic component, comprising:
at least one camera integrated in the hydraulic component, the at least one camera arranged such that at least one surface that is prone to wear and/or at least one edge that is prone to wear is observable using the camera; and
a computation element configured to control a light source and/or the camera in dependence on operating data of the hydraulic component determined by a sensor.

10. The hydraulic component according to claim 7 , wherein the light source is a stroboscope.

11. The hydraulic component according to claim 1 , wherein at least one of the hydraulic component and the camera includes a transparent/transmissive element configured to protect at least one of the camera and a light source from dirt.

12. The hydraulic component according to claim 1 , wherein the hydraulic component is one of an axial piston machine, a directional valve, a control valve, a servo hydraulic axis, a hydraulic cylinder, a piston accumulator, and an assembly.

13. A hydraulic component, comprising:
at least one camera integrated in the hydraulic component, the at least one camera arranged such that at least one surface that is prone to wear and/or at least one edge that is prone to wear is observable using the camera,
wherein the hydraulic component is a directional valve, and
wherein the camera is arranged in a valve body, such that a control edge is observable using the camera.

14. The hydraulic component according to claim 12 , wherein the hydraulic component is an axial piston machine, and the camera is arranged in a connection cover such that a sliding surface is observable.

15. The hydraulic component according to claim 14 , wherein the hydraulic component is an axial piston machine, and the camera is arranged in at least one of an inlet channel and an outlet channel in the connection cover.

16. The hydraulic component according to claim 13 , further comprising:
an evaluation unit configured to evaluate an image of the camera and to make a first statement about wear relating to the at least one surface and/or the at least one edge.

17. The hydraulic component according to claim 16 , wherein the evaluation unit includes and/or is connected to a screen so as to enable data to be evaluated by a person.

18. The hydraulic component according to claim 16 , wherein the evaluation unit includes an automated image evaluation unit.

19. The hydraulic component according to claim 16 , further comprising:
at least one sensor configured to determine operating data of the hydraulic component,
wherein the evaluation unit is configured to effect a second statement about wear relating to the hydraulic component based on the operating data.

20. The hydraulic component according to claim 19 , wherein the evaluation unit is configured to compare the second statement about wear that is based on the operating data to the first statement about wear that is based on the image.
