Shaft for an open-end spinning rotor and method of making same

摘要

In the case of a shaft for an open-end spinning rotor a supporting element is fixed in a concentric recess of the shaft. The supporting element is disposed with a radially extending supporting surface against a vibrating ball of a step bearing. A ball is used as a supporting element, a section of which ball projects out of the recess. The projecting section is radially flattened in relation to the shaft and thus forms the radially extending supporting surface. Because of its ball shape, the supporting element can be easily placed in the recess. In the case of a misaligned arrangement of the vibrating ball, the radial flattening prevents the axial position of the open-end spinning rotor from being displaced and undesirable radial forces being exerted on the shaft.
