<p>A bearing arrangement comprising a first part (1) having a bearing surface (1a), a second part (2) having a surface being made of an electrically conductive material and being arranged in sliding contact with the bearing surface (1a),and means for detecting wear of the bearing surface. The wear detecting means comprise a sensor (3), which is arranged in the first part (1), made at least partly of an electrically conductive material and comprises a first area (3d) and a second area (3e). The first area (3d) is electrically connected to the surface of the second part (2) so that an open electrical circuit is formed when the bearing surface (1a) is intact, and when the bearing surface (1a) wears down to a certain predefined thickness, the second area (3e) comes into electrical con- tact with the surface of the second part (2) closing the electrical circuit. The wear detecting means further comprise means for detecting closing of the electrical circuit. The invention also concerns a method for detecting wear of a bearing surface and use of a bearing arrangement in a turbocharger for an internal combustion engine.</p> |
