Embodiment Construction

[0070] In the figures, identical structural elements have the same reference numerals.

[0071] figure 1 A longitudinal section of the bearing assembly is shown without an end-side cover.

[0072]The bearing assembly 10 inter alia comprises a (bearing) housing 12 comprising a flange 14 (here exemplarily in the shape of a ring) and a substantially hollow cylindrical attachment axially connected to the flange 14. Attachment section 16. As an option, the flange 14 can also be oval, elliptical or at least triangular. In the region of the attachment portion 16 , a rolling bearing 20 , comprising an inner ring 22 and an outer ring 24 between which a plurality of rolling bodies 26 roll, is received in the seat 12 . On both sides of the rolling elements 26, a first sealing disc (seal disc) 28 and a second sealing disc 30 are arranged between the inner ring 22 and the outer ring 24 for optimizing the rolling bearing 20 against (protection against) damage environmental influences, e...

Abstract

The invention relates to a bearing assembly (10) comprising a rolling bearing (20) sealed on both sides by first and second sealing discs (28, 30), the rolling bearing comprising an inner ring (22) and an outer ring (24) A plurality of rolling elements (26) rolling between, wherein the outer ring is received in the attachment portion (16) of the seat (12) in a manner capable of slightly pivoting relative to the longitudinal central axis (40) of the bearing assembly, and the inner ring is arranged on the shaft (34) to be supported. The flange (14) of the seat is sealed relative to the shaft by means of a seal assembly (50), an end cover (70) comprising a sealing element (80), in particular an O-ring, can be attached in a tight-tight manner to the seat's The free end (60) of the attachment portion facing away from the flange, the interior (100) of the seat comprises at least one sealing stop (102, 104). Due to the triple seal provided in this way, the bearing assembly is reliably protected against penetrating or spray water and dirt particles which may be carried therein.

Description

technical field [0001] The invention relates to a bearing assembly comprising a rolling bearing sealed on both sides by first and second sealing discs, the rolling bearing comprising a plurality of rolling elements rolling between an inner ring and an outer ring, wherein the outer ring of the bearing assembly is Received in the attachment portion of the seat in a slightly pivotable manner relative to the longitudinal center axis of the bearing assembly, the inner ring is arranged on the shaft to be supported. Background technique [0002] A wide variety of sealed rolling bearings or bearing assemblies are known from the prior art. Such rolling bearings are preferred for bearing applications under particularly severe conditions, such as are widely used in agriculture. [0003] It is particularly disadvantageous that conventional sealed rolling bearings have only a short service life, since water and dirt particles entering them can lead to increased corrosion and / or washing-...
