Embodiment Construction

[0021] figure 1 shows a perspective view of a rolling bearing arrangement 01 according to the invention, while figure 2 An exploded representation of a rolling bearing arrangement is shown. The rolling bearing device 01 comprises a rolling bearing 02 and a sensor device 03 fixed on the rolling bearing. The rolling bearing 02 has at least one outer ring 04 , an inner ring 05 and rolling bodies (not shown) arranged in a rolling body space between the outer ring 04 and the inner ring 05 . One of the two bearing rings 04, 05 is rotatable relative to the other bearing ring. A sealing ring 07 is respectively connected to the outer ring 04 on both sides, and the sealing ring extends in the radial direction between the inner ring 05 and the outer ring 04 . The sealing ring 07 protects the inside of the rolling bearing from impurities.

[0022] The sensor device 03 has an outer ring 08 and an inner ring 09 . The diameter of the outer ring 08 corresponds to the diameter of the out...

Abstract

The present invention relates to a sensor device (03) for a rolling bearing (02) having an outer ring (04) and an inner ring (05) which is rotatable relative to the outer ring. The sensor device comprises at least one sensor which is connectable in a rotationally fixed manner to one of the two bearing rings (04, 05) and a signal transmitter (20) which is connectable in a rotationally fixed manner to the other of the two bearing rings (04, 05). The sensor device comprises an outer ring (08) that can be fastened on an end face of the outer ring (04) of the rolling bearing (02) as well as an inner ring (09) that can be fastened on a front face of the inner ring (05) of the rolling bearing (02), wherein sensor and signal transmitter (20) are arranged on mutually opposite lateral surfaces of the outer and inner rings (08, 09). The fastening of the rings on the end faces can be carried out with the aid of an adhesive film. The invention further relates to a rolling bearing arrangement (01) comprising such a sensor device (03).

Description

technical field [0001] The invention relates to a sensor device for a rolling bearing having an outer ring and an inner ring, one of the two bearing rings being rotatable relative to the other of the two bearing rings. The sensor device comprises at least one sensor connected in a rotationally fixed manner to one of the two bearing rings and a signal generator connected in a rotationally fixed manner to the other of the two bearing rings. The invention also relates to a rolling bearing arrangement having a rolling bearing and a sensor device connected to the rolling bearing. Background technique [0002] Rolling bearing arrangements with integrated sensor units (also referred to as sensor bearings) are used to detect various bearing state variables, such as rotational speed, temperature and angle of rotation. A disadvantage of the known solutions is that such rolling bearing arrangements are generally custom-made and are therefore only available within a certain range of va...
