Embodiment Construction

[0024] figure 1 A sealing structure 1 is shown which comprises a carrier body 2 made of metallic material and a sealing element 6 made of a PTFE compound reinforced with glass fibers. The L-shaped support has an annular element 15 and a disk-shaped flange 16 which has an end face 5 on the side facing away from said element 15 . The sealing element 6 is fastened materially to the end face 5 of the carrier 2 by gluing. Here, an adhesive layer 11 is provided on the carrier 2 . The sealing element 6 is arranged on the carrier body 2 in such a way that the first section 7 of the sealing element 6 forms a dynamic sealing lip and the second section 8 of the sealing element 6 forms a static seal. In order to improve the static sealing effect, the sealing element 6 has a coating 9 in the form of a sealant in the region of the second section 8 . In the region of the first section 7 the sealing element 6 has an oil return geometry 12 in the form of an oil return groove.

Abstract

The invention relates to a seal (1) comprising a sealing element (6) and an L-shaped support body (2) that has an annular element (15) and a disc-shaped flange (16), wherein the flange (16) has an end face (5) on the side facing away from the element (15), and wherein the sealing element (6) is located on the end face (5).

Description

technical field [0001] The invention relates to a sealing arrangement comprising a sealing element and an L-shaped support body having an annular element and a disk-shaped flange, which has an end face on a side facing away from the element. Background technique [0002] Sealing structures of this type are generally known in the prior art. Prior art seals include a support body made of metal and a disk-shaped sealing element made of PTFE. The sealing element is fastened to the carrier body via an intermediate layer of polymer material. Sealing structures of this type therefore comprise at least three materials. Furthermore, the sealing element is designed in such a way that the carrier body and the contact surfaces of the sealing element connected to the intermediate layer lead to excessively high production costs. In certain configurations, the media being sealed may be in contact with the support or interface. This becomes a problem if the medium being sealed is chemic...
