A support disc for a bearing for a shaft of an open nend - spinning rotor and bearing arrangement for a shaft of an open nend - spinning rotor

摘要

A supporting disk (4) for a bearing (1) for a shaft (3) of an open nend - spinning rotor (2) has a disk-shaped base body (8) and a on an outer circumference of the base body (8) applied coating (9), having a radial outer surface of a running surface (10) for the shaft (3) of the open nend - spinning rotor (2) provides. The running surface (10) is formed by two in the axial direction of the supporting disc (4) spaced apart from one another, bearing surfaces (11) and formed between the contact surfaces (11) is a groove-like recess (12) is formed. The groove-like recess (12) has a width (b), the at least equal to wide or wider than a total support width (ab) of the two supporting surfaces (11). A bearing (1) for a shaft (3) of an open nend - spinning rotor (2), which with its shaft (3) in a wedge-shaped gap (7) of pairs of support disks (4) is mounted, the support disks (4) is designed accordingly.
