| 摘要 |
<p>The invention relates to a prop disc bearing, in particular for the shank of an open-end spinning rotor, where the shank (1) is mounted in a wedge-shaped nip formed by prop discs (4, 5) and the prop discs (4, 5) have a running surface (40, 50) made of a resilient coating which is pressed against the shank (1). The running surface (40, 50) has at least one discontinuity, which is formed by a recess and bridged by the contact line of the shank (1). The discontinuity can take various forms, but is preferably flute-shaped. This discontinuity reduces the wear on the running surface. <IMAGE></p> |
