Abstract
Disclosed is a bearing assembly, in particular a large bearing assembly, including at least one inner ring and at least one outer ring, between which at least one circumferential seal is disposed that slips on a circumferential slip surface of the inner ring or of the outer ring, wherein guide channels are formed on the slip surface or the circumferential seal.
Claims6
A large bearing assembly comprising:
- at least one first bearing ring,
- at least one second bearing ring having a first slip surface, and
- a first seal having a seal lip, the first seal being mounted to the at least one first bearing ring with the seal lip in contact with the first slip surface,
- wherein the first slip surface includes guide channels,
- wherein the guide channels have a pitch of greater than or equal to 4 mm per rotation,
- wherein a circumferential distance between the guide channels is smaller than the pitch,
- wherein the at least one second bearing ring includes a second slip surface configured to be contacted by a seal lip of a second seal,
- wherein the second slip surface includes guide channels, and
- wherein the guide channels in the first slip surface are oriented oppositely to the guide channels in the second slip surface.
