摘要:
The present invention relates to a rolling bearing arrangement comprising a rolling bearing (02) having an outer ring (03) and an inner ring (04) and a strain sensor device (09), which is integrated in the outer ring (03) or fastened to the outer ring (03), for measuring axial loads acting on the rolling bearing (02). The strain sensor device (09) has an annular main body. The invention is characterized in that the strain sensor device (09) has, on its inner end face, at least one force introduction element (12) extending in the circumferential direction in the shape of a circle segment. The force introduction element (12) is connected to the annular main body (10) via at least one web-shaped coupling element (13). The strain sensor element (09) has, on its outer end face facing away from the rolling bearing (02), at least one recess (14) for accommodating a strain sensor (15). The recess (14) extends over the force introduction element (12) at least in the circumferential direction, the coupling element (13) having a smaller extent in the radial direction than the recess (14). The annular main body (10) is secured to the frame.

A method is specified for producing a strain gauge arrangement (14) on the surface of a machine element (2), particularly a bearing ring (3) or a shaft (17), wherein a deformation-sensitive measurement layer (6) and a protective layer (8) situated thereabove are applied to the surface. The protective layer (8) is locally removed by means of laser processing and the exposed measurement layer (6) is contacted electrically. A machine element (2), particularly a bearing ring (3) or a shaft (17), with a strain gauge arrangement (14) produced according to the method is also specified.
