The invention relates to a coupling (1) with a bellows-protected interlocking driving connection (2), at least comprising a hub (3) and a sleeve (4), wherein the driving connection (2) is arranged between hub (3) and sleeve (4), wherein the driving connection (2) is protected by a bellows (5), wherein the bellows (5) is located in a recess (6) of the hub (3) and is fastened at one end to the sleeve end region (8) and at the other end opposite the sleeve end region (8) to the hub (3), wherein the annular recess (6) is bounded at least by an annular hub inner surface (16) directed towards the driving connection (2) and by an opposite hub outer surface (9) formed with respect to the end side (11) of the hub (3), wherein there is an annular gap (10) between the sleeve end region (8) and the hub outer surface (9) of the recess (6). The intention is to avoid dust and dirt penetrating the bellows clearance which faces away from the driving connection, in particular the bellows-element clearances, which are designed in cross section as wave troughs and face the hub outer surface, in the recess present within the hub in the region between bellows and hub outer surface. For this purpose, at least one elastic annular sealing element (12; 121, 122, 123, 124) is arranged in the region between the annular bellows (5), which is of wavy design, with bellows elements (25) and the hub outer surface (9), wherein the sealing element (12) seals at least one bellows-element clearance (21), which is adjacent to the annular gap (10) and is designed in cross section as a wave trough, in a bellows element (25). |
