Abstract
The invention relates to a sealing arrangement (2) that seals at least one radial intermediate space (21) between at least one inner bearing ring (3) and at least one outer bearing ring (5). Said sealing arrangement (2) comprises at least one first support (17) that supports at least one elastic seal (18) and a second support (19) which supports at least one encoder (10) located outside the intermediate space (21). The encoder (10) is radially oriented towards at least one sensor (14) that is disposed above the encoder (10) in a radially outward direction.
Claims17
A sealing arrangement (2, 28, 40, 47) which seals at least one radial interspace (21) between at least one inner bearing ring (3, 41, 52) and at least one outer bearing ring (5, 33, 42, 49), it being the case that the sealing arrangement (2, 28, 40, 47)
- is provided with at least a first support (17, 30, 43, 48a), the first support (17, 30, 43, 48a) bearing at least one elastic seal (18, 34, 39, 44, 51),
- has a second support (19, 32, 37, 45, 48b), the second support (19, 32, 37, 45, 48b) bearing at least one encoder (10) arranged outside the interspace (21), and the encoder (10) being oriented radially toward at least one sensor (14) arranged above the encoder (10) in the radially outward direction,
- has a dirt deflector (23, 31, 53) on the inner bearing ring (3, 41, 52), the dirt deflector (23, 31, 53) and the first support (17, 30, 43, 48a) being arranged such that they can be rotated relative to one another, and the seal (18, 34, 39, 44, 51) butting at least against the dirt deflector (23, 31, 53), characterized in that the encoder engages around the inner bearing ring, and in that the encoder (10) is covered fully at least in the radial direction and at least partially in the axial direction by means of a covering element (20, 29, 48), the covering element (20, 29, 48) being rotationally fixed on one of the bearing rings (3, 5, 33, 41, 42, 49, 52).
