ABSTRACT:
An axially acting undulating washer or wave-shaped spring consisting of a closed annular member which comprises a central X-axis and which is periodically wave-shaped across the circumference, wherein a wave line extends so as to monotonically rise or fall between a plurality of identical minima and identical maxima and wherein in the minima and maximum of the wave line there are formed contact points of the annular member relative to axis-normal contact faces, wherein, starting from each minimum and maximum, the annular member, on both sides, i.e. in each circumferential direction, comprises at least two wave line portions which directly adjoin one another and which, with an increasing axial load, are individually flattened and made to contact and contact faces one after the other.
