Problems solved by technology

The disadvantage of both embodiments is that the metal carrier element interfering antenna or the loop design is hardly suitable as an antenna for an IC tag, since a dipole with two ends spaced apart from one another cannot be constructed
A segmented metal carrier element, although suitable as a dipole for the antenna, does not overall give the sealing element the required mechanical stability
Furthermore, the disadvantage is that additional installation space is required to accommodate the IC identifier, antenna or suitable insulation
Furthermore, it is regarded as disadvantageous that the insulation of the antenna from the metal carrier element is wasteful and since it is implemented by a sealing element formed from a soft elastomer—essentially unreliable especially with regard to mechanical stress

Embodiment Construction

[0022] figure 1 An annular sealing element 1 for a rolling bearing not shown further is shown. The sealing element 1 includes an IC identification element 2 and an antenna 3 , wherein the antenna is designed as a segmented annular element and has a slot 4 . The antenna 3 and the main body 5 of the sealing element 1 are correspondingly designed concentrically. The antenna 3 is arranged inside the main body 5 of the sealing element 1 and thus in figure 1 are only shown in dashed lines. The IC-identification element 2 includes a chip (not shown in detail) which can receive and store data.

[0023] figure 2 Shown is the main body 5 of the sealing element 1 , which has the IC identifier 2 . The IC tag 2 is arranged inside a carrier element 6 , wherein the carrier element 6 is made of a rigid material, in this case a polyamide-based thermoplastic material. The outer surface of carrier element 6 is surrounded, except for section 7 , by a sealing element 8 made of a soft elasto...

Abstract

The invention relates to a sealing element for a bearing, especially a rolling bearing, and a bearing, especially a rolling bearing, wherein the sealing element comprises: a sealing element (8) made of an elastic material, at least one load-bearing element made of a rigid material , an IC-identifier (2) and an antenna (3) for the IC-identifier. The object of improving the sealing element or the bearing in one way, namely keeping the sealing element mechanically sufficiently stable and substantially not interfering with the function of the antenna is achieved for the sealing element or the bearing according to the invention by at least A carrier element (6) consists of a non-metallic material.

Description

technical field [0001] The invention relates to a sealing element for a bearing, in particular for a rolling bearing, according to the preamble of claim 1 and to a bearing according to claim 9 . Background technique [0002] For bearings, in particular rolling bearings, it is known to attach an IC identification to the bearing, which stores data relating to the bearing, for example the model number. An antenna is also provided for the IC identification, by means of which the information contained in the IC identification can be read out or the information can be transmitted to the IC identification. Furthermore, it is known to require that the IC identification element or its antenna have electromagnetic radiation in the microwave range, so that it is emitted by RFID (Radio Frequency Identification) technology for bearings, in particular rolling bearings. [0003] US 2002 / 0186134 A1 describes a rolling bearing with an IC identification, in which an RFID element is inserted ...
