Abstract
A sealing arrangement comprising first and second machine elements which can turn relative to one another and delimit an installation space to be sealed for a sealing ring. The sealing ring has at least one static sealing area, which is connected, in a form-locking manner, by an anchoring bead, with a congruently shaped first indentation in the first machine element. The sealing ring has at least one dynamic sealing area with at least one first sealing lip that touches a first undercut of the second machine element with a sealing effect. The dynamic sealing area has at least one second sealing lip, which is connected with the first sealing lip by a connecting piece.
Claims7
A sealing arrangement comprising:
- first and second machine elements which can turn relative to one another and delimit an installation space to be sealed for a sealing ring;
- the sealing ring being placed with a sealing effect within the installation space;
- the sealing ring having at least one static sealing area that is connected in a form-locking manner by a first anchoring bead with a congruently shaped first indentation in the first machine element;
- the sealing ring having at least one dynamic sealing area, the dynamic sealing area having at least one first sealing lip that touches with a sealing effect a first undercut of the second machine element that extends in a radial direction and the dynamic sealing area having at least one second sealing lip that is connected by a connecting piece with the first sealing lip, the second sealing lip touching with a sealing effect a sealing surface of the first machine element, the first and second sealing lips and the connecting piece being substantially in the shape of an anchor;
- wherein the static sealing area has a second anchoring bead that is connected in a form-locking manner with a congruently shaped second indentation in the first machine element and that the sealing surface has a second undercut that extends in a radial direction and on which the second sealing lip can be placed with a sealing effect.
