Embodiment Construction

[0029] figure 1A perspective sectional view of a sealed rolling bearing 1 according to the invention is shown. Rolling bearing 1 is a spherical roller bearing, which has a first bearing ring 2 (ie, outer ring), a second bearing ring 3 (ie, inner ring), and a large number of rolling elements 4, which Roll on the raceway 5,6 of two bearing rings 2,3. The rolling elements 4 are guided by a cage 13 .

[0030] The rolling body space 7 formed between the raceways 5 , 6 is partially filled with a lubricant, not shown. Lubricant can be refilled via the relubrication hole 8 and is prevented from escaping into the surroundings by the two seals 11 , 12 arranged on the axial ends 9 , 10 .

[0031] The seals 11 , 12 are each anchored to the first bearing ring 2 by means of fastening sections 14 . This means that the seals 11 , 12 are connected to the bearing ring 2 in a rotationally fixed manner.

[0032] The gaskets 11 , 12 at the two axial ends 9 , 10 are identical.

Abstract

The invention relates to a sealed rolling bearing (1) having an annular sealing gasket (11, 12) which seals a rolling body space (7) in the axial direction, wherein the sealing gasket (11, 12) have a fastening section (14) for the rotationally fixed connection to the bearing ring (2) of the rolling bearing (1), and wherein the sealing gasket (11, 12) has its fastening section ( 14) Anchored in the surrounding groove (22) of the bearing ring. According to the invention, it is provided that the fastening section (14) has a first clamping element in the form of a barb (19) and a second clamping element in the form of an annular flange (20), and the barbs (19) A non-positive connection is formed with the opposing surfaces of the flange (20) and the groove (22).

Description

technical field [0001] The invention relates to a sealed rolling bearing with an annular seal, which seals the rolling body space in the axial direction, wherein the seal has a fastening section for a rotationally fixed connection to a bearing ring of the rolling bearing, In addition, the sealing washer is anchored with its fastening section in the circumferential groove of the bearing ring. Such sealed rolling bearings, such as sealed spherical roller bearings, are particularly suitable for bearing locations in which, for reasons of space and / or costs, it is not possible to provide a seal separate from the rolling bearing. Background technique [0002] On the one hand, a sealed rolling bearing should be able to protect the rolling element space, that is to say the region in which the rolling bearing is arranged radially between the raceways in radial bearings, from the surrounding environment. In this case, the penetration of dirt, fluids or other foreign objects into the ...
