Abstract
An arrangement including two components with differential speed and an elastic oil transmission ring. One of the two components forms a groove for accommodating the oil transfer ring. The oil transfer ring has a U-shaped cross-section with a first lip and a second lip, wherein the first and second lips are spaced apart and run parallel to each other. The first and second lips each form a contact surface on their outer sides. The contact surfaces lie against two opposing wall surfaces of the groove when the oil transfer ring is mounted between the two components. The contact surfaces are spaced further apart than from each other than the two wall surfaces of the groove when the oil transfer ring is not mounted between the two components.
